The main treatment is symptomatic, since the underlying genetic defect cannot be corrected as of 2015. Symptomatic treatment is surgical.

Treatment of a laryngeal cleft depends on the length and resulting severity of symptoms. A shallow cleft (Type I) may not require surgical intervention. Symptoms may be able to be managed by thickening the infant's feeds. If symptomatic, Type I clefts can be sutured closed or injected with filler as a temporary fix to determine if obliterating the cleft is beneficial and whether or not a more formal closure is required at a later date. Slightly longer clefts (Type II and short Type III) can be repaired endoscopically. Short type IV clefts extending to within 5 mm below the innominate artery can be repaired through the neck by splitting the trachea vertically in the midline and suturing the back layers of the esophagus and trachea closed. A long, tapered piece of rib graft can be placed between the esophageal and tracheal layers to make them rigid so the patient will not require a tracheotomy after the surgery and to decrease chances of fistula postoperatively. Long Type IV clefts extending further than 5 mm below the innominate artery cannot be reached with a vertical incision in the trachea, and therefore are best repaired through cricotracheal resection. This involves separating the trachea from the cricoid cartilage, leaving the patient intubated through the trachea, suturing each of the esophagus and the back wall of the trachea closed independently, and then reattaching the trachea to the cricoid cartilage. This prevents the need for pulmonary bypass or extracorporeal membrane oxygenation.

ECG leads must be placed in reversed positions on a person with dextrocardia. In addition, when defibrillating someone with dextrocardia, the pads should be placed in reverse positions. That is, instead of upper right and lower left, pads should be placed upper left and lower right.

When heart transplantation is required in a person with situs inversus, reconstruction of the venous pathways to accommodate a normal donor heart is a major, but not insurmountable, challenge.

There no standardized effective treatment strategies for the condition. Severe fatal respiratory failure can develop; long-term treatment with macrolides such as clarithromycin, erythromycin and azithromycin has been empirically applied for the treatment of primary ciliary dyskinesia in Japan, though controversial due to the effects of the medications.

Most (>95%) infants with biliary atresia will undergo an operation designed to retain and salvage the native liver, restore bile flow and reduce the level of jaundice. This is known as the Kasai procedure (after Morio Kasai, the Japanese surgeon who first developed the technique) or hepatoportoenterostomy. Although the procedure is not thought of as curative, it may relieve jaundice, and stop liver fibrosis allowing normal growth and development. Published series from Japan, North America and the UK show that bilirubin levels will fall to normal values in about 50-55% of infants allowing 40-50% to retain their own liver to reach the age of 5 and 10 years (and beyond). Liver transplantation is an option for those children whose liver function and symptoms fail to respond to a Kasai operation.

Recent large-scale studies by Davenport et al. ("Annals of Surgery", 2008) show that the age of the patient is not an absolute clinical factor affecting prognosis. The influence of age differs according to the disease etiology—i.e., whether biliary atresia is isolated, cystic (CBA), or accompanied by splenic malformation (BASM).

It is widely accepted that corticosteroid treatment after a Kasai operation, with or without choleretics and antibiotics, has a beneficial effect on postoperative bile flow and can clear jaundice, but the dosing and duration of the ideal steroid protocol are controversial. Furthermore, it has been observed in many retrospective longitudinal studies that corticosteroid treatment does not prolong survival of the native liver or transplant-free survival. Davenport et al. also showed ("Hepatology" 2007) that short-term, low-dose steroid therapy following a Kasai operation had no effect on the mid- or long-term prognosis of biliary atresia patients.

Situs inversus (also called situs transversus or oppositus) is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement of internal organs is known as situs solitus while situs inversus is generally the mirror image of situs solitus. Although cardiac problems are more common than in the general population, most people with situs inversus have no medical symptoms or complications resulting from the condition, and until the advent of modern medicine it was usually undiagnosed.

Situs inversus is found in about 0.01% of the population, or about 1 person in 10,000. In the most common situation, situs inversus totalis, it involves complete transposition (right to left reversal) of all of the abdominal organs. The heart is not in its usual position in the left chest, but is on the right, a condition known as dextrocardia (literally, right-hearted). Because the relationship between the organs is not changed, most people with situs inversus have no medical symptoms or complications, although they should wear a medical identification tag to warn emergency medical staff that the patient's internal organs are reversed from normal so they can act accordingly, e.g. by listening for a heartbeat on the right rather than left side of the chest.

In rarer cases such as situs ambiguus or heterotaxy, situs cannot be determined. In these patients, the liver may be midline, the spleen absent or multiple, and the bowel malrotated. Often, structures are duplicated or absent altogether. This is more likely to cause medical problems than situs inversus totalis.

Aglossia (aglossia congenita) is a congenital defect resulting in a partial development or complete absence of a tongue.

Aglossiais commonly associated with craniofacial and limb defects (Adactylia syndrome) and is thought to belong to a family of oromandibular limb hypogenesis syndrome or OLHS. It is believed to be caused by heat-induced vascular disruption near the fourth week of embryonic development.

The first known case was reported in the early 18th century by a member of the prominent De Jussieu family in France and cases to this day remain rare.

Impossible Syndrome, or Chondrodysplasia situs inversus imperforate anus polydactyly, is a complex combination of human congenital malformations (birth defects).

The malformations include chondrodysplasia (improper growth of bone and cartilage), situs inversus totalis (chest and abdominal organs all a mirror image of normal), cleft larynx and epiglottis, hexadactyly (six digits) on hands and feet, diaphragmatic hernia, pancreatic abnormalities, kidney abnormal on one side and absent on the other side, micropenis and ambiguous genitalia, and imperforate anus.

Only one case of Impossible Syndrome has been reported; the infant was premature and stillborn.

Each of the symptoms of situs ambiguous must be managed with appropriate treatment dependent upon the organ system involved. Intestinal malrotation is treated surgically using the Ladd procedure. This procedure widens a fold in the peritoneum so that the intestines can be placed in non-rotated formation. Unfortunately, it is not possible to return the bowel to a normal morphology However, 89% of patients that undergo the Ladd surgery experience a complete resolution of symptoms.

Following cholangiogram, a Kasai Procedure is usually performed in cases of biliary atresia. In this surgery, a Y-shaped shunt is used to passage bile from the liver directly to the intestine. If this is unsuccessful, liver transplantation can be considered based on the overall health of the patient. Fortunately, the Kasai Procedure is successful in approximately 80% of patients. Following the operation, patients are advised to take fat-soluble vitamins, choleretics, and anti-inflammatory medications.

Functionally asplenic patients have an elevated lifetime risk of septicemia, as they have no functional spleen for fighting infection. For this reason, asplenic patients are under constant observation for any signs of fever or infection. In the case of infection, patients are placed on controlled empiric antibiotic therapy to avoid development of antibiotic resistance. This therapy battles infection by both gram-positive and gram-negative bacteria.

Right-atrial and left-atrial isomerism and associated pulmonary issues are treated in a series of steps based on the severity of symptoms. Isomeric patients are first treated by inserting a shunt that will move incoming blood through the pulmonary circuit. The Fontan procedure routes blood through the patient's single ventricle, to the lungs, and into systemic circulation. This process is favorable in patients aged 2 – 5 years old. Unfortunately, 20-30% of patients will require a heart transplant. Left-atrial isomeric patients have less severe complications, as they typically have 2 functional ventricles. In this case, they can undergo biventricular repair to form 2 separate ventricles and functional associated valves.

Prognosis for patients with situs ambiguous is quite varied, considering the spectrum of clinical complications. Infants who experience severe cyanosis at birth die within hours of delivery if medical intervention is not immediate. Alternatively, longevity of neonates with mild cardiac lesions is unaffected. Ten percent of patients born with right atrial isomerism die by the age of 5 without intervention. Fortunately, improvements in therapies has increased the 5-year survival to 30-74% for right atrial isomeric patients and 65-84% for left atrial isomeric patients based on the cause of their disease.

In the absence of congenital heart defects, individuals with situs inversus are phenotypically normal, and can live normal healthy lives, without any complications related to their medical condition. There is a 5–10% prevalence of congenital heart disease in individuals with situs inversus totalis, most commonly transposition of the great vessels. The incidence of congenital heart disease is 95% in situs inversus with levocardia.

Many people with situs inversus totalis are unaware of their unusual anatomy until they seek medical attention for an unrelated condition, such as a rib fracture or a bout of appendicitis. The condition may also be discovered during the administration of certain medicines or during tests such as a Barium meal or enema. The reversal of the organs may then lead to some confusion, as many signs and symptoms will be on the atypical side. For example, if an individual with situs inversus develops appendicitis, they will present to the physician with lower left abdominal pain, since that is where their appendix lies. Thus, in the event of a medical problem, the knowledge that the individual has situs inversus can expedite diagnosis. People with this rare condition should inform their doctors before an examination, so the doctor can redirect their search for heart sounds and other signs. Wearing a medical identification tag can help inform health care providers in the event the person is unable to communicate.

Situs inversus also complicates organ transplantation operations as donor organs will more likely come from situs solitus (normal) donors. As hearts and livers are chiral, geometric problems arise placing an organ into a cavity shaped in the mirror image. For example, a person with situs inversus who requires a heart transplant needs all the vessels to the transplant donor heart reattached to their existing ones. However, the orientation of these vessels in a person with situs inversus is reversed, necessitating steps so that the blood vessels join properly.

Hanhart syndrome (also known as Aglossia adactylia; Hypoglossia-hypodactylia syndrome; Peromelia with micrognathia) is a congenital disorder that causes an undeveloped tongue and malformed extremities and fingers.

There are frequent associated congenital anomalies all related to deviations in the development of anatomical asymmetries in early embryonic stages. These conditions considered together are called "polysplenia syndrome".

Associated conditions include heterotaxy syndrome, intestinal malrotation, situs inversus, biliary atresia, and several cardiac malformations. Associated cardiac conditions include dextrocardia, atrial situs ambiguus, ventricular inversion, and VA concordance with left posterior aorta.

Although present, the multiple small spleens are often ineffective; this is termed functional asplenia.

The inheritance of Impossible syndrome is suspected to be autosomal recessive, which means the affected gene is located on an autosome, and two copies of the gene - one from each parent - are required to have an infant with the disorder.

There is no standard approach to the treatment of lymphangiomatosis and treatment often is aimed at reducing symptoms. Surgical intervention may be indicated when complications arise and a number of reports of response to surgical interventions, medications, and dietary approaches can be found in the medical literature.

Unfortunately, there is no standardized treatment for lymphangiomatosis and no cure.

Treatment modalities that have been reported in the medical literature, by system, include:

Polysplenia or Chaudhrey's disease is a congenital disease manifested by multiple small accessory spleens, rather than a single, full-sized, normal spleen. Polysplenia sometimes occurs alone, but it is often accompanied by other developmental abnormalities. Conditions associated with polysplenia include gastrointestinal abnormalities, such as intestinal malrotation or biliary atresia, as well as cardiac abnormalities, such as dextrocardia.

interferon alpha 2b, bisphosphonates (i.e. pamidronate), surgical resection, radiation therapy, sclerotherapy, percutaneous bone cement, bone grafts, prosthesis, surgical stabilization.

Michels syndrome is a syndrome characterised by intellectual disability, craniosynostosis, blepharophimosis, ptosis, epicanthus inversus, highly arched eyebrows, and hypertelorism. And vary in other symptoms such as asymmetry of the skull, eyelid, and anterior chamber anomalies, cleft lip and palate, umbilical anomalies, and growth and cognitive development.

Currently there is no cure for these disorders. Medical care is directed at treating systemic conditions and improving the person's quality of life. Physical therapy and daily exercise may delay joint problems and improve the ability to move.

Changes to the diet will not prevent disease progression, but limiting milk, sugar, and dairy products has helped some individuals experiencing excessive mucus.

Surgery to remove tonsils and adenoids may improve breathing among affected individuals with obstructive airway disorders and sleep apnea. Sleep studies can assess airway status and the possible need for nighttime oxygen. Some patients may require surgical insertion of an endotrachial tube to aid breathing. Surgery can also correct hernias, help drain excessive cerebrospinal fluid from the brain, and free nerves and nerve roots compressed by skeletal and other abnormalities. Corneal transplants may improve vision among patients with significant corneal clouding.

Enzyme replacement therapy (ERT) are currently in use or are being tested. Enzyme replacement therapy has proven useful in reducing non-neurological symptoms and pain. Currently BioMarin Pharmaceutical produces enzyme replacement therapies for MPS type I and VI. Aldurazyme is an enzymatic replacement therapy for alpha-L-iduronidase produced by BioMarin for use in Type I MPS. In July 2006, the United States Food and Drug Administration approved a synthetic version of I2S produced by Shire Pharmaceuticals Group, called Elaprase, as a treatment for MPS type II (Hunter syndrome).

Bone marrow transplantation (BMT) and umbilical cord blood transplantation (UCBT) have had limited success in treating the mucopolysaccharidoses. Abnormal physical characteristics, except for those affecting the skeleton and eyes, may be improved, but neurologic outcomes have varied. BMT and UCBT are high-risk procedures and are usually performed only after family members receive extensive evaluation and counseling.

Twenty to 27% of individuals with a laryngeal cleft also have a tracheoesophageal fistula and approximately 6% of individuals with a fistula also have a cleft. Other congenital anomalies commonly associated with laryngeal cleft are gastro-oesophageal reflux, tracheobronchomalacia, congenital heart defect, dextrocardia and situs inversus. Laryngeal cleft can also be a component of other genetic syndromes, including Pallister-Hall syndrome and G syndrome (Opitz-Friaz syndrome).

The management of this condition can be done via-improvement of any electrolyte imbalance, as well as, hypertension and anemia treatment as the individuals condition warrants.

Patients will generally need to be followed by an endocrinologist. If hypogonadism is present, testosterone treatment should be considered in all individuals regardless of cognitive abilities due to positive effects on bone health, muscle strength, fatigue, and endurance, with possible mental health/behavioral benefits as well.

Most children with XXYY will have some developmental delays and learning disabilities. Therefore the following aspects should be checked and monitored: psychology (cognitive and social–emotional development), speech/language therapy, occupational therapy, and physical therapy. Consultation with a developmental pediatrician, psychiatrist, or neurologist to develop a treatment plan including therapies, behavioral interventions, educational supports, and psychotropic medications for behavioral and psychiatric symptoms should be arranged.

Common diagnoses such as learning disability/ID, ADHD, autism spectrum disorders, mood disorders, tic disorders, and other mental health problems should be considered, screened for, and treated. Good responses to standard medication treatments for inattention, impulsivity, anxiety, and mood instability are seen in this group and such treatment can positively impact academic progress, emotional wellbeing and long-term outcome.

Poor fine motor coordination and the development of intention tremor can make handwriting slow and laborious, and occupational therapy and keyboarding should be introduced at an early age to facilitate schoolwork and self-help skills. Educational difficulties should be evaluated with a full psychological evaluation to identify discrepancies between verbal and performance skills and to identify individual academic needs. Expressive language skills are often affected throughout the lifespan and speech therapy interventions targeting expressive language skills, dyspraxia, and language pragmatics may be needed into adulthood. Adaptive skills (life skills) are a significant area of weakness necessitating community-based supports for almost all individuals in adulthood.

Additional treatment recommendations based on the individual strengths and weaknesses in XXYY syndrome may be required.

Blepharophimosis is a congenital condition characterized by a horizontally narrow palpebral fissure. It is also part of a syndrome blepharophimosis, ptosis, and epicanthus inversus syndrome, also called blepharophimosis syndrome, which is a condition where the patient has bilateral ptosis with reduced lid size, vertically and horizontally. The nasal bridge is flat and there is hypoplastic orbital rim. Both the vertical and horizontal palpebral fissures (eyelid opening) are shortened; the eyes are also spaced more widely apart than usual, also known as telecanthus.

Vignes (1889) probably first described this entity, a dysplasia of the eyelids.

Blepharophimosis, ptosis, epicanthus inversus syndrome or BPES is a rare disease characterized by the conditions it is named after: blepharophimosis, ptosis, and epicanthus inversus.

Blepharophimosis syndrome is an autosomal dominant characterized by blepharophimosis (horizontal shortening of the palpebral fissures), ptosis (upper eyelid drooping, usually with the characteristics of congenital ptosis), epicanthus inversus (skin folds by the nasal bridge, more prominent lower than upper lid), and telecanthus (widening of the distance between the medial orbital walls). This syndrome is caused by mutations in the FOXL2 gene, either with premature ovarian failure (BPES type I) or without (BPES type II). It may also be associated with lop ears, ectropion, hypoplasia of superior orbital rims, and hypertelorism.

The goal of treatment in Panner disease is to relieve pain. Treatment for Panner Disease is very minimal because in most children the bones repair their blood supply and rebuild themselves and this leads to the rebuilding of the growth plate and the capitellum returns to its normal shape. The period of rebuilding and regrowth varies from child to child and can last anywhere between weeks to several months. To relieve the pain, the child is restricted from participating in sports and activities until the elbow is healed and to also rest the affected elbow. Rest will allow for the pain to be relieved and return of full elbow movement. It may also be recommended for children to apply an icepack or heat to the elbow to alleviate pain and swelling. If the child has great difficulty bending and straightening the arm then physical therapy may also be recommend. Occasionally, it is recommended for children to use nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen to also reduce pain and swelling. For treatment, Panner Disease heals well in children with rest and restriction of physical activity and sports using the affected arm. The prognosis is also good with treatment and the affected capitellum is remodeled. Irregularities of the capitellum and surrounding elbow area can both be seen by radiograph and MRI. When treatment is effective the flattened and fragmented capitellum is completely remodeled and returns to its normal circular shape, and also the high intensity signal on a MRI T2 series disappears. These results indicate that the capitellum is completely remodeled and the child is able to return to normal physical and sports activities.
