Pregnant mothers are advised to take folic acid supplements to reduce risk of iniencephaly by up to 70%. Pregnant mothers are also advised not to take antiepileptic drugs, diuretics, antihistamines, and sulfa drugs, all of which have been associated with increased risk for neural tube defects.

Since newborns with iniencephaly so rarely survive past childbirth, a standard treatment does not exist.

Treatments of NTDs depends on the severity of the complication. No treatment is available for anencephaly and infants usually do not survive more than a few hours. Aggressive surgical management has improved survival and the functions of infants with spina bifida, meningoceles and mild myelomeningoceles. The success of surgery often depends on the amount of brain tissue involved in the encephalocele. The goal of treatment for NTDs is to allow the individual to achieve the highest level of function and independence. Fetal surgery in utero before 26 weeks gestation has been performed with some hope that there is benefit to the final outcome including a reduction in Arnold–Chiari malformation and thereby decreases the need for a ventriculoperitoneal shunt but the procedure is very high risk for both mother and baby and is considered extremely invasive with questions that the positive outcomes may be due to ascertainment bias and not true benefit. Further, this surgery is not a cure for all problems associated with a neural tube defect. Other areas of research include tissue engineering and stem cell therapy but this research has not been used in humans.

In 1996, the United States Food and Drug Administration published regulations requiring the addition of folic acid to enriched breads, cereals, flour and other grain products. It is important to note that during the first four weeks of pregnancy (when most women do not even realize that they are pregnant), adequate folate intake is essential for proper operation of the neurulation process. Therefore, women who could become pregnant are advised to eat foods fortified with folic acid or take supplements in addition to eating folate-rich foods to reduce the risks of serious birth defects.

In Canada, mandatory fortification of selected foods with folic acid has been shown to reduce the incidence of neural tube defects by 46%.

Women who may become pregnant are advised to get 400 micrograms of folic acid daily. Women who have previously given birth to a child with a neural tube defect may benefit from a supplement containing 4.0 mg/5.0 mg in the UK mg daily, following advice provided by their doctor.

Since this condition is usually coupled with other neurological disorders or deficits, there is no known cure for cerebral polyopia. However, measures can be taken to reduce the effects of associated disorders, which have proven to reduce the effects of polyopia. In a case of occipital lobe epilepsy, the patient experienced polyopia. Following administration of valproate sodium to reduce headaches, the patient’s polyopia was reduced to palinopsia. Further, after administering the anticonvulsant drug Gabapentin in addition to valproate sodium, the effects of palinopsia were decreased, as visual perseveration is suppressed by this anticonvulsant drug. Thus, in cases of epilepsy, anticonvulsant drugs may prove to reduce the effects of polyopia and palinopsia, a topic of which should be further studied.

In other cases of polyopia, it is necessary to determine all other present visual disturbances before attempting treatment. Neurological imaging can be performed to determine if there are present occipital or temporal lobe infarctions that may be causing the polyopia. CT scans are relatively insensitive to the presence of cerebral lesions, so other neurological imaging such as PET and MRI may be performed. The presence of seizures and epilepsy may also be assessed through EEG. In addition, motor visual function should be assessed through examination of pupillary reactions, ocular motility, optokinetic nystagmus, slit-lamp examination, visual field examination, visual acuity, stereo vision, bimicroscopic examination, and funduscopic examination. Once the performance of such functions have been assessed, a plan for treatment can follow accordingly. Further research should be conducted to determine if the treatment of associated neurological disturbances can reduce the effects of polyopia.

Historically, to temporarily alleviate symptoms, patients have tried positional maneuvers, such as tilting their head to one side or upside down, lie down on their backs, or sit in a chair with their head between their knees. Similarly, a routine of lying down four times per day with legs elevated to around 20 inches for at least two weeks has been attempted as well. Depending on the underlying cause of the disorder, the individual may need to remove caffeine from their diet, reduce exercise, or gain weight. It may be the case that the symptoms are induced by anxiety; anxiolytic drugs or supplements (e.g., GABA) combined with the removal of caffeine from the diet could offer a simple strategy to determine if anxiety is the root cause.

Estrogen (Premarin) nasal drops or saturated potassium iodide have been used to induce edema of the eustachian tube opening. Nasal medications containing diluted hydrochloric acid, chlorobutanol, and benzyl alcohol have been reported to be effective in some patients, with few side effects. Food and Drug Administration approval is still pending, however.

In extreme cases surgical intervention may attempt to restore the Eustachian tube tissues with fat, gel foam, or cartilage or scar it closed with cautery. These methods are not always successful.

Cephalic disorders (from the Greek word "κεφάλι", meaning "head") are congenital conditions that stem from damage to, or abnormal development of, the budding nervous system. Cephalic means "head" or "head end of the body."

Cephalic disorders are not necessarily caused by a single factor, but may be influenced by hereditary or genetic conditions, nutritional deficiencies, or by environmental exposures during pregnancy, such as medication taken by the mother, maternal infection, or exposure to radiation. Some cephalic disorders occur when the cranial sutures (the fibrous joints that connect the bones of the skull) join prematurely. Most cephalic disorders are caused by a disturbance that occurs very early in the development of the fetal nervous system.

The human nervous system develops from a small, specialized plate of cells on the surface of the embryo. Early in development, this plate of cells forms the neural tube, a narrow sheath that closes between the third and fourth weeks of pregnancy to form the brain and spinal cord of the embryo. Four main processes are responsible for the development of the nervous system: cell proliferation, the process in which nerve cells divide to form new generations of cells; cell migration, the process in which nerve cells move from their place of origin to the place where they will remain for life; cell differentiation, the process during which cells acquire individual characteristics; and cell death, a natural process in which cells die.

Damage to the developing nervous system is a major cause of chronic, disabling disorders and, sometimes, death in infants, children, and even adults. The degree to which damage to the developing nervous system harms the mind and body varies enormously. Many disabilities are mild enough to allow those afflicted to eventually function independently in society. Others are not. Some infants, children, and adults die, others remain totally disabled, and an even larger population is partially disabled, functioning well below normal capacity throughout life.

The National Institute of Neurological Disorders and Stroke (NINDS) is currently "conducting and supporting research on normal and abnormal brain and nervous system development."

Surgical treatment should be considered when the patient has a trigger thumb bilaterally and when the patient has a severe trigger thumb. Severe is defined as when the thumb is locked so that the thumb cannot be flexed or extended either passively or actively. Surgical treatment should also be considered when observation and/or splint therapy hasn’t achieved sufficient results after 49 months. Unlike the surgical treatment given for adults, which is unambiguously a surgical release of the A1 pulley of the thumb, the optimum surgical treatment for infants has not yet been discerned. In case of infants, research has shown that only in 15% of the cases A1 pulley release alone is sufficient. In most of the cases there was an additional annular pulley structure distal to the A1 to be released resolving the triggering: the so-called Av pulley or variable pulley. Therefore infants and adults need to be treated differently as the main problem is different.

Also called myofunctional therapy, the basic treatment aims of orofacial myofunctional therapist is to reeducate the movement of muscles, restore correct swallowing patterns, and establish adequate labial-lingual postures. An interdisciplinary nature of treatment is always desirable to reach functional goals in terms of swallowing, speech, and other esthetic factors. A team approach has been shown to be effective in correcting orofacial myofunctional disorders. The teams include an orthodontist, dental hygienist, certified orofacial myologist, general dentist, otorhinolaryngologist, and a speech-language pathologist.

The conservative treatment consists of observation in time. Studies show that the trigger thumb spontaneously resolves in 49 months. According to Leung et al., trigger thumbs in infants resolve spontaneously in 63% of the cases. No residual deformities were found and there is no recurrence once resolved. Residual deformity is defined as persistent flexion deformities of the thumb and radial deviation at the IPJ. Extension exercises and splinting can be added to the observation. These two elements have favourable results in improvement in flexion impairment of the thumb. However, compared to observation, the benefit of merely extension exercises and splinting are still unclear.

It has been recommended to attempt conservative treatment first, before attempting surgical treatment.

Some clinicians believe that partial stenosis of the NLD with symptomatic epiphora sometimes responds to surgical intubation of the entire lacrimal drainage system. This procedure should be performed only if the tubes can be passed easily. In complete NLD obstruction, intubation alone is not effective, and a DCR should be considered.

Where known, the ICD-10 code is listed below.

- Anencephaly (Q00.0)

- Colpocephaly (ICD10 unknown)

- Holoprosencephaly (Q04.2)

- Ethmocephaly (ICD10 unknown)

- Hydranencephaly (Q04.3)

- Iniencephaly (Q00.2)

- Lissencephaly (Q04.3)

- Megalencephaly (Q04.5)

- Microcephaly (Q02)

- Porencephaly (Q04.6)

- Schizencephaly (Q04.6)

A DCR is the treatment of choice for most patients with acquired NLD obstruction. Surgical indications include recurrent dacryocystitis, chronic mucoid reflux, painful distension of the lacrimal sac, and bothersome epiphora. For patients with dacryocystitis, active infection should be cleared, if possible, before DCR is performed.

The definitive treatment of pyloric stenosis is with surgical pyloromyotomy known as Ramstedt's procedure (dividing the muscle of the pylorus to open up the gastric outlet). This surgery can be done through a single incision (usually 3–4 cm long) or laparoscopically (through several tiny incisions), depending on the surgeon's experience and preference.

Today, the laparoscopic technique has largely supplanted the traditional open repairs which involved either a tiny circular incision around the navel or the Ramstedt procedure. Compared to the older open techniques, the complication rate is equivalent, except for a markedly lower risk of wound infection. This is now considered the standard of care at the majority of children's hospitals across the US, although some surgeons still perform the open technique. Following repair, the small 3mm incisions are hard to see.

The vertical incision, pictured and listed above, is no longer usually required, though many incisions have been horizontal in the past years.

Once the stomach can empty into the duodenum, feeding can begin again. Some vomiting may be expected during the first days after surgery as the gastrointestinal tract settles. Rarely, the myotomy procedure performed is incomplete and projectile vomiting continues, requiring repeat surgery. Pyloric stenosis generally has no long term side-effects or impact on the child's future.

Septal perforations are managed with a multitude of options. The treatment often depends on the severity of symptoms and the size of the perforations. Generally speaking anterior septal perforations are more bothersome and symptomatic. Posterior septal perforations, which mainly occur iatrogenically, are often managed with simple observation and are at times intended portions of skull base surgery. Septal perforations that are not bothersome can be managed with simple observation. While no septal perforation will spontaneously close, for the majority of septal perforations that are unlikely to get larger observation is an appropriate form of management. For perforations that bleed or are painful, initial management should include humidification and application of salves to the perforation edges to promote healing. Mucosalization of the perforation edges will help prevent pain and recurrent epistaxis and majority of septal perforations can be managed without surgery.

For perforations in which anosmia, or the loss of smell, and a persistent whistling are a concern the use of a sillicone septal button is a treatment option. These can be placed while the patient is awake and usually in the clinic setting. While complications of button insertion are minimal, the presence of the button can be bothersome to most patients.

For patients who desire definitive close, surgery is the only option. Prior to determining candidacy for surgical closure, the etiology of the perforation must be determined. Often this requires a biopsy of the perforation to rule out autoimmune causes. If a known cause such as cocaine is the offending agent, it must be ensured that the patient is not still using the irritant.

For those that are determined to be medically cleared for surgery, the anatomical location and size of the perforation must be determined. This is often done with a combination of a CT scan of the sinuses without contrast and an endoscopic evaluation by an Ear Nose and Throat doctor. Once dimensions are obtained the surgeon will decide if it is possible to close the perforation. Multiple approaches to access the septum have been described in the literature. While sublabial and midfacial degloving approaches have been described, the most popular today is the rhinoplasty approach. This can include both open and closed methods. The open method results in a scar on the columella, however, it allows for more visibility to the surgeon. The closed method utilizes an incision all on the inside of the nose. The concept behind closure includes bringing together the edges of mucosa on each side of the perforation with minimal tension. An interposition graft is also often used. The interposition graft provides extended stability and also structure to the area of the perforation. Classically, a graft from the scalp utilizing temporalis fascia was used. Kridel, et al., first described the usage of acellular dermis so that no further incisions are required; they reported an excellent closure rate of over 90%. Overall perforation closure rates are variable and often determined by the skill of the surgeon and technique used. Often surgeons who claim a high rate of closure choose perforations that are easier to close. An open rhinoplasty approach also allows for better access to the nose to repair any concurrent nasal deformities, such as saddle nose deformity, that occur with a septal perforation.

Some evidence suggests that indomethacin administration on the first day of life to all preterm infants reduces the risk of developing a PDA and the complications associated with PDA. Indomethacin treatment in premature infants also may reduce the need for surgical intervention.

So far, there is no certain treatment that can completely stop snoring. Almost all treatments for snoring revolve around lessening the breathing discomfort by clearing the blockage in the air passage. Medications are usually not helpful in treating snoring symptoms, though they can help control some of the underlying causes such as nasal congestion and allergic reactions. Doctors, therefore, often recommend lifestyle changes as a first line treatment to stop snoring. This is the reason snorers are advised to lose weight (to stop fat from pressing on the throat), stop smoking (smoking weakens and clogs the throat), avoid alcohol and sedative medications before bedtime (they relax the throat and tongue muscles, which in turn narrow the airways) and sleep on their side (to prevent the tongue from blocking the throat).

A number of other treatment options are also used to stop snoring. These range from over-the-counter aids such as nasal sprays, nasal strips or nose clips, lubricating sprays, oral appliances and "anti-snore" clothing and pillows, to unusual activities such as playing the didgeridoo. However, one needs to be wary of over-the-counter snore treatments that have no scientific evidence to support their claims, such as stop-snore rings or wrist worn electrical stimulation bands.

Infantile pyloric stenosis is typically managed with surgery; very few cases are mild enough to be treated medically.

The danger of pyloric stenosis comes from the dehydration and electrolyte disturbance rather than the underlying problem itself. Therefore, the baby must be initially stabilized by correcting the dehydration and the abnormally high blood pH seen in combination with low chloride levels with IV fluids. This can usually be accomplished in about 24–48 hours.

Intravenous and oral atropine may be used to treat pyloric stenosis. It has a success rate of 85-89% compared to nearly 100% for pyloromyotomy, however it requires prolonged hospitalization, skilled nursing and careful follow up during treatment. It might be an alternative to surgery in children who have contraindications for anesthesia or surgery, or in children whose parents do not want surgery.

Orthopedic pillows are the least intrusive option for reducing snoring. These pillows are designed to support the head and neck in a way that ensures the jaw stays open and slightly forward. This helps keep the airways unrestricted as possible and in turn leads to a small reduction in snoring.

Neonates without adverse symptoms may simply be monitored as outpatients, while symptomatic PDA can be treated with both surgical and non-surgical methods. Surgically, the DA may be closed by ligation (though support in premature infants is mixed), either manually tied shut, or with intravascular coils or plugs that leads to formation of a thrombus in the DA.

Devices developed by Franz Freudenthal block the blood vessel with woven structures of nitinol wire.

Because prostaglandin E2 is responsible for keeping the DA open, NSAIDS (which can inhibit prostaglandin synthesis) such as indomethacin or a special form of ibuprofen have been used to initiate PDA closure. Recent findings from a systematic review concluded that, for closure of a PDA in preterm and/or low birth weight infants, ibuprofen is as effective as Indomethacin. It also causes fewer side effects (such as transient renal insufficiency) and reduces the risk of necrotising enterocolitis. Another recent review showed that paracetamol may be effective for closure of a PDA in preterm infants.

More recently, PDAs can be closed by percutaneous interventional method (avoiding open heart surgery). A platinum coil can be deployed via a catheter through the femoral vein or femoral artery, which induces thrombosis (coil embolization). Alternatively, a PDA occluder device , composed of nitinol mesh, is deployed from the pulmonary artery through the PDA.

One dental textbook defines it as: “Dollicofacial, there is excess of lower facial height usually associated with lower occlusal and mandibular plane angles.” This is often associated “with vertical maxillary excess and mandibular hypoplasia.” Luc P. M. Tourne, a Fellow in the Department of TMJ and Craniofacial Pain at the University of Minnesota School of Dentistry, noted: "There is a clinically recognizable facial morphology, the long face syndrome, which has been incompletely described in the literature," However, her study of 31 adults with this syndrome, which included "analysis of esthetics, skeletal morphology, and occlusion" confirmed "this basic dentofacial deformity" has associations " with excessive vertical growth of the maxilla." She reported that closed bite and dental open are two pf the syndrome's variants.

The treatment for young patients troubled by long face syndrome is to halt and control descent of the lower jaw and to prevent the eruption of posterior teeth. In severe cases of deformity, a mixture of orthodontics and orthognathic surgery may be the only effective solution. The long term (more than 6 years) effectiveness of surgical treatments for long face syndrome has been subject to study.

"In the American literature, the terms long-face syndrome and short-face syndrome are often used." To be sure, there are reported "long and the short face anomalies" and open bite cases. However, in the opinion of Hugo Obwegeser, there is no medical justification for naming theme as a "syndrome" the signs and symptoms do not meet the definitional threshold.

There is controversy concerning the use of the descriptor "long-face syndrome." While increased anterior "total and lower face height" in many ages, combined with vertical maxillary excess in adults has been observed, the causes are controversial. Specifically, there is disagreement about possible potential environmental influences on genetic components.

Anecdotally, it was said to be a genetic condition, which could only be corrected with “massive amounts” of debilitating, frequent and long dental and facial reconstructive surgery.

For children, there is a concern that mouth breathing can contribute to the development of long face syndrome. A recent study finds that it is a growing problem which should be treated as "It won't just go away." In addition to mouth breathing, it may be associated with sleep apnea.

Because of Long face syndrome's sometime association with pediatric obstructive sleep apnea (OSA) and allergic reactions, it is essential that treating physicians differentiate the conditions and the treatments; treating one may not cure the other. Multilevel coblation surgery is sometimes used to correct moderate to severe OSA, and Long Face Syndrome can be a rare factor in considering surgery.

Tongue crib is a removable applianced placed in the maxillary arch for the purpose of stopping the tongue thrusting habit. This appliance maybe used in patients with mixed dentition or permanent dentition. Tongue crib is attached through a bar to two bands placed on the upper 1st molars. The crib is shaped like a horseshoe with metal bars that prevent the thrusting habit. Tongue crib is known to eliminate habits in about 90% of the patients. (citation needed). Huang et al. published a study in 1990 which stated that patients who achieved a positive overbite during their tongue crib therapy had a good chance of maintaining that overbite after their orthodontic treatment. They credited this change to a change in the posterior positioning of the tongue due to the crib therapy.

Some of the side-effects of using a tongue-crib therapy is that this appliance may trap a lot of food which may cause inflammation around the appliance. In addition, repeated contact of tongue with the appliance may also lead to an imprint on the tongue which will self-resolve once the appliance is removed. It is important to note that this type of therapy will only work in patients who do not have a skeletal open bite tendency. Skeletal open bite tendency may be addressed via surgery or other treatments depending on the severity.

Rachischisis (Greek: "rhachis - ῥάχις" - spine, and "schisis - σχίσις" - split) is a developmental birth defect involving the neural tube. This anomaly occurs in utero, when the posterior neuropore of the neural tube fails to close by the 27th intrauterine day. As a consequence the vertebrae overlying the open portion of the spinal cord do not fully form and remain unfused and open, leaving the spinal cord exposed. Patients with rachischisis have motor and sensory deficits, chronic infections, and disturbances in bladder function. This defect often occurs with anencephaly.

Craniorachischisis is a variant of rachischisis that occurs when the entire spinal cord and brain are exposed - simultaneous complete rachischisis and anencephaly. It is incompatible with life; affected pregnancies often end in miscarriage or stillbirth. Infants born alive with craniorachischisis die soon after birth.

There are not systematic reviews or randomized clinical control trials related to correction of open bite with partial tongue glossectomy but several case reports have been published indicating successful treatment of open bite with this surgical approach. Macroglossia has been reported to cause open bite and bimaxillary protrusion and is also known to be make orthodontic treatment unstable after its completion.

There are several stages to treating an anal fistula:

Definitive treatment of a fistula aims to stop it recurring. Treatment depends on where the fistula lies, and which parts of the internal and external anal sphincters it crosses.

There are several options:

- Doing nothing — a drainage seton can be left in place long-term to prevent problems. This is the safest option although it does not definitively cure the fistula.

- Lay-open of fistula-in-ano — this option involves an operation to cut the fistula open. Once the fistula has been laid open it will be packed on a daily basis for a short period of time to ensure that the wound heals from the inside out. This option leaves behind a scar, and depending on the position of the fistula in relation to the sphincter muscle, can cause problems with incontinence. This option is not suitable for fistulae that cross the entire internal and external anal sphincter.

- Cutting seton — if the fistula is in a high position and it passes through a significant portion of the sphincter muscle, a cutting seton (from the Latin "seta", "bristle") may be used. This involves inserting a thin tube through the fistula tract and tying the ends together outside of the body. The seton is tightened over time, gradually cutting through the sphincter muscle and healing as it goes. This option minimizes scarring but can cause incontinence in a small number of cases, mainly of flatus. Once the fistula tract is in a low enough position it may be laid open to speed up the process, or the seton can remain in place until the fistula is completely cured. This was the traditional modality used by physicians in Ancient Egypt and formally codified by Hippocrates, who used horsehair and linen.

- Seton stitch — a length of suture material looped through the fistula which keeps it open and allows pus to drain out. In this situation, the seton is referred to as a draining seton. The stitch is placed close to the ano-rectal ring – which encourages healing and makes further surgery easy.

- Fistulotomy — till anorectal ring

- Colostomy — to allow healing

- Fibrin glue injection is a method explored in recent years, with variable success. It involves injecting the fistula with a biodegradable glue which should, in theory, close the fistula from the inside out, and let it heal naturally. This method is perhaps best tried before all others since, if successful, it avoids the risk of incontinence, and creates minimal stress for the patient.

- Fistula plug involves plugging the fistula with a device made from small intestinal submucosa. The fistula plug is positioned from the inside of the anus with suture. According to some sources, the success rate with this method is as high as 80%. As opposed to the staged operations, which may require multiple hospitalizations, the fistula plug procedure requires hospitalization for only about 24 hours. Currently, there are two different anal fistula plugs cleared by the FDA for treating ano-rectal fistulae in the United States. This treatment option does not carry any risk of bowel incontinence. In the systematic review published by Dr Pankaj Garg, the success rate of the fistula plug is 65-75%.

- Endorectal advancement flap is a procedure in which the internal opening of the fistula is identified and a flap of mucosal tissue is cut around the opening. The flap is lifted to expose the fistula, which is then cleaned and the internal opening is sewn shut. After cutting the end of the flap on which the internal opening was, the flap is pulled down over the sewn internal opening and sutured in place. The external opening is cleaned and sutured. Success rates are variable and high recurrence rates are directly related to previous attempts to correct the fistula.

- LIFT Technique is a novel modified approach through the intersphincteric plane for the treatment of fistula-in-ano, known as LIFT (ligation of intersphincteric fistula tract) procedure. LIFT procedure is based on secure closure of the internal opening and removal of infected cryptoglandular tissue through the intersphincteric approach. Essential steps of the procedure include, incision at the intersphincteric groove, identification of the intersphincteric tract, ligation of intersphincteric tract close to the internal opening and removal of intersphincteric tract, scraping out all granulation tissue in the rest of the fistulous tract, and suturing of the defect at the external sphincter muscle. The procedure was developed by Thai colorectal surgeon, Arun Rojanasakul, The first reports of preliminary healing result from the procedure were 94% in 2007. Additional ligation of the intersphincteric fistula tract did not improve the outcome after endorectal advancement flap.

- Fistula clip closure (OTSC Proctology) is the latest surgical development, which involves the closure of the internal fistula opening with a superelastic clip made of nitinol (OTSC). During surgery, the fistula tract is debrided with a special fistula brush and the clip is transanally applied with the aid of a preloaded clip applicator. The surgical principle of this technique relies on the dynamic compression and permanent closure of the internal fistula opening by the superelastic clip. Consequently, the fistula tract dries out and heals instead of being kept open by continuous feeding with stool and fecal organisms. This minimally-invasive sphincter-preserving technique has been developed and clinically implemented by the German surgeon Ruediger Prosst. First clinical data of the clip closure technique demonstrate a success rate of 90% for previously untreated fistulae and a success rate of 70% for recurrent fistulae.

- PERFACT Procedure is another latest addition to the armamentarium to treat complex and highly complex fistula-in-ano. It is a minimally cutting procedure as both the anal sphincters (internal and external sphincters) are not cut/damaged at all. Therefore, the risk of incontinence is minimal. PERFACT procedure (proximal superficial cauterization, emptying regularly fistula tracts and curettage of tracts) entails two steps: superficial cauterization of mucosa at and around the internal opening and keeping all the tracts clean. The principle is to permanently close the internal opening by granulation tissue. This is achieved by superficial electrocauterization at and around the internal opening and subsequently allowing the wound to heal by secondary intention. Early results of this procedure are quite encouraging for complex fistula-in-ano (86.4% in highly complex anal fistulae). The procedure is effective even in fistula associated with abscess, supralevator fistula-in-ano and fistula where the internal opening is non-localizable.
