The major treatment is surgery for most babies. The type of surgery which they would undergo differs from age and strength they have. The main reason of doing the surgery is to alleviate pressure on the brain, and create a space for brain developing and growing. It would improve infant’s appearance.

The first one is Traditional surgery. During surgery, they make an incision in the baby's scalp and cranial bones, and reshape the portion of the skull. Sometimes plates and screws, often made of material that is absorbed over time, are used to hold the bones in place. Surgery, which is performed during general anesthesia, usually takes hours.

After surgery, your baby remains in the hospital for at least three days. Some children may require a second surgery later because, the craniosynostosis recurs. Also, children with facial deformities often require future surgeries to reshape their faces.

Another one is Endoscopic surgery. This less invasive form of surgery isn't an option for everyone. But in certain cases, the surgeon may use a lighted tube (endoscope) inserted through one or two small scalp incisions over the affected suture. The surgeon then opens the suture to enable your baby's brain to grow normally. Endoscopic surgery usually takes about an hour, causes less swelling and blood loss, and shortens the hospital stay, often to one day after surgery.

High quality evidence is lacking for cranial remolding orthosis (baby helmet) for the positional condition and use for this purpose is controversial. If conservative treatment is unsuccessful helmets may help to correct abnormal head shapes. These helmets are used to treat deformational plagiocephaly, brachycephaly, scaphocephaly and other head shape deformities in infants 3–18 months of age by gently allowing the head shape to grow back into a normal shape. This type of treatment has been used for severe deformations.

The condition may improve to some extent as the baby grows, but in some cases, treatment can improve the shape of a baby’s head.

The primary goal in surgical intervention is to allow normal cranial vault development to occur. This can be achieved by excision of the prematurely fused suture and correction of the associated skull deformities. If the synostosis goes uncorrected, the deformity will progressively worsen not only threatening the aesthetic aspect, but also the functional aspect. This is especially the case in the asymmetric conditions, such as unilateral coronal synostosis, with compromised function of the eyes and the jaw.

In addition signs of compromised neurodevelopment have been seen amongst all the synostoses, although this may also be caused by primary maldevelopment of the brain and can thus not be prevented by surgical intervention.

There are a few basic elements involved in the surgical intervention aimed at normalization of the cranial vault.

- One is minimization of blood loss, which is attempted by injection of vasoconstrictive agents (i.e. epinephrine) seven to ten minutes before scalp incision. In addition is the initiation of surgery delayed until blood products are physically present in the operating room.

- Another general agreement is the avoidance of the use of titanium plates in the fixation of the skull. The complication following this procedure is gradual movement of the titanium plates towards the brain, induced by resorption of the innermost bone layer of the skull and deposition of new bone on the outermost layer, thereby integrating the titanium plates. In some cases, the plates were even seen coming in direct contact with the brain. Absorbable plates are now used instead.

This condition can be corrected by surgery if the child is young enough. The use of a cranial remolding orthosis can also benefit the child if the child begins wearing it at an early age.

The prevention of the complications mentioned above plays an important role in the discussion about the timing of the surgery. The general consensus is now to perform surgery in late infancy, i.e. between six and twelve months. In this time frame the efficacy of surgery is enhanced due to several reasons:

- The bone is still more malleable and can be remodelled relatively 'simply' by greenstick fractures of the bone. At approximately one year of age the bone has become more mineralized and brittle and needs to be fastened to the surrounding bone with sutures or an absorbable plate.

- Reshaping of the cranial vault most commonly means excision of the bones and adjustment of the shape. Replacement of the bones can leave 'gaps' which are readily re-ossified before the age of one year, but need bony filling thereafter.

The reason why most surgeons will not intervene until after the age of six months is the greater risk that blood loss poses before this age. If possible it is preferred to wait until after three months of age when the anaesthetic risks are decreased.

Surgery is not performed in early childhood in every country. In some countries surgical intervention can take place in the late teens.

It is important that families seek out a Pediatric Craniofacial Physician who has experience with craniosynostosis for proper diagnosis, surgical care, and followup.

Patients must have early consultation with craniofacial and orthopaedic surgeons, when craniofacial, clubfoot, or hand correction is indicated to improve function or aesthetics. Operative measures should be pursued cautiously, with avoidance of radical measures and careful consideration of the abnormal muscle physiology in Freeman–Sheldon syndrome. Unfortunately, many surgical procedures have suboptimal outcomes, secondary to the myopathy of the syndrome.

When operative measures are to be undertaken, they should be planned for as early in life as is feasible, in consideration of the tendency for fragile health. Early interventions hold the possibility to minimise developmental delays and negate the necessity of relearning basic functions.

Due to the abnormal muscle physiology in Freeman–Sheldon syndrome, therapeutic measures may have unfavourable outcomes. Difficult endotracheal intubations and vein access complicate operative decisions in many DA2A patients, and malignant hyperthermia (MH) may affect individuals with FSS, as well. Cruickshanks et al. (1999) reports uneventful use of non-MH-triggering agents. Reports have been published about spina bifida occulta in anaesthesia management and cervical kyphoscoliosis in intubations.

There are two less common types of McGillivray syndromes are: Metopic synostosis (trigonocephaly). The metopic suture runs from your baby's nose to the sagittal suture. Premature fusion gives the scalp a triangular appearance. Another one is Lambdoid synostosis (posterior plagiocephaly). This rare form of craniosynostosis involves the lambdoid suture, which runs across the skull near the back of the head. It may cause flattening of your baby's head on the affected side. A misshapen head doesn't always indicate craniosynostosis. For example, if the back of your baby's head appears flattened, it could be the result of birth trauma or your baby's spending too much time on his or her back. This condition is sometimes treated with a custom-fit helmet that helps mold your baby's head back into a normal position.

Patients and their parents must receive psychotherapy, which should include marriage counselling. Mitigation of lasting psychological problems, including depression secondary to chronic illness and posttraumatic stress disorder (PTSD), can be very successfully addressed with early interventions. This care may come from the family physician, or other attending physician, whoever is more appropriate; specialist care is generally not required. Lewis and Vitulano (2003) note several studies suggesting predisposal for psychopathology in paediatric patients with chronic illness. Esch (2002) advocates preventive psychiatry supports to facilitate balance of positive and negative stressors associated with chronic physical pathology. Patients with FSS should have pre-emptive and ongoing mixed cognitive therapy-psychodynamic psychotherapy for patients with FSS and cognitive-behavioural therapy (CBT), if begun after onset of obvious pathology.

Adler (1995) cautioned the failure of modern medicine to implement the biopsychosocial model, which incorporates all aspects of a patient’s experience in a scientific approach into the clinical picture, often results in chronically-ill patients deferring to non-traditional and alternative forms of therapy, seeking to be understood as a whole, not a part, which may be problematic among patients with FSS.

Furthermore, neuropsychiatry, physiological, and imaging studies have shown PTSD and depression to be physical syndromes, in many respects, as they are psychiatric ones in demonstrating limbic system physiological and anatomy disturbances. Attendant PTSD hyperarousal symptoms, which additionally increase physiological stress, may play a part in leading to frequent MH-like hyperpyrexia and speculate on its influence on underlying myopathology of FSS in other ways. PTSD may also bring about developmental delays or developmental stagnation, especially in paediatric patients.

With psychodynamic psychotherapy, psychopharmacotherapy may need to be considered. Electroconvulsive therapy (ECT) is advised against, in light of abnormal myophysiology, with predisposal to MH.

Café au lait spots can be removed with lasers. Results are variable as the spots are often not completely removed or can come back after treatment. Often, a test spot is treated first to help predict the likelihood of treatment success.

Scaphocephaly is a type of cephalic disorder which occurs when there is a premature fusion of the sagittal suture. The sagittal suture joins together the two parietal bones of skull. Scaphocephaly is the most common of the craniosynostosis conditions and is characterized by a long, narrow head.

The term is from Greek "skaphe" meaning 'light boat or skiff' and "kephale" meaning 'head') describes a specific shape of a long narrow head that resembles an inverted boat.

The majority of patients remain symptom free and able to maintain binocularity with only a slight face turn. Amblyopia is uncommon and, where present, rarely dense. This can be treated with occlusion, and any refractive error can also be corrected.

Duane syndrome cannot be cured, as the "missing" cranial nerve cannot be replaced, and traditionally there has been no expectation that surgery will result in any increase in the range of eye movement. Surgical intervention, therefore, has only been recommended where the patient is unable to maintain binocularity, where they are experiencing symptoms, or where they are forced to adopt a cosmetically unsightly or uncomfortable head posture in order to maintain binocularity. The aims of surgery are to place the eye in a more central position and, thus, place the field of binocularity more centrally also, and to overcome or reduce the need for the adoption of an abnormal head posture. Occasionally, surgery is not needed during childhood, but becomes appropriate later in life, as head position changes (presumably due to progressive muscle contracture).

Surgical approaches include:

- Medial rectus recession in the involved eye or both eyes. By weakening the medial rectus muscles this procedure improves the crossed-eye appearance but does not improve outward eye movements (abductions).

- Morad et al. showed improved abduction after modest unilateral medial rectus recession and lateral rectus resection in a subgroup of patients with mild eye retraction and good adduction before surgery.

- Lateral transposition of the vertical muscles described by Rosenbaum has been shown to improve range of movement of the eye. The surgical procedure produces 40-65 degrees of binocular field. Orbital wall fixation of the lateral rectus muscle (muscle is disinserted and reattached to lateral orbital wall) is recommended an effective method to inactivate a lateral rectus muscle in cases of marked anomalous innervation and severe cocontraction.

Dolichocephaly (derived from the Ancient Greek δολιχός, meaning "long") is a condition where the head is longer than would be expected, relative to its width. In humans, scaphocephaly is a form of dolichocephaly.

Dolicocephalic dogs (such as German Shepherds) have elongated noses. This makes them vulnerable to fungal diseases of the nose such as aspergillosis. In humans the anterior–posterior diameter (length) of dolichocephaly head is more than the transverse diameter (width). It has an incidence of 1 in every 4,200 babies.

It can present be in cases of Sensenbrenner syndrome, Crouzon syndrome, Sotos syndrome as well as Marfan syndrome.

Although dolichocephaly may be associated with some other abnormalities, alone it is just a normal variation; unless symptomatic, it is not a cause for concern. Early diagnosis can be made by X-ray or ultrasonography. Treatment is not essential.

Macrocephaly is a condition in which the head is abnormally large; this includes the scalp, the cranial bone, and the contents of the cranium.

Macrocephaly may be pathological, but many people with abnormally large heads or large skulls are healthy. Pathologic macrocephaly may be due to megalencephaly (enlarged brain), hydrocephalus (water on the brain), cranial hyperostosis (bone overgrowth), and other conditions. Pathologic macrocephaly is called "syndromic" when it is associated with any other noteworthy condition, and "nonsyndromic" otherwise. Pathologic macrocephaly can be caused by congenital anatomic abnormalities, genetic conditions, or by environmental events.

Many genetic conditions are associated with macrocephaly, including familial macrocephaly related to the holgate gene, autism, "PTEN" mutations such as Cowden disease, neurofibromatosis type 1, and tuberous sclerosis; overgrowth syndromes such as Sotos syndrome (cerebral gigantism), Weaver syndrome, Simpson-Golabi-Behmel syndrome (bulldog syndrome), and macrocephaly-capillary malformation (M-CMTC) syndrome; neurocardiofacial-cutaneous syndromes such as Noonan syndrome, Costello syndrome, Gorlin Syndrome, (also known as Basal Cell Nevus Syndrome) and cardiofaciocutaneous syndrome; Fragile X syndrome; leukodystrophies (brain white matter degeneration) such as Alexander disease, Canavan disease, and megalencephalic leukoencephalopathy with subcortical cysts; and glutaric aciduria type 1 and D-2-hydroxyglutaric aciduria.

At one end of the genetic spectrum, duplications of chromosomes have been found to be related to autism and macrocephaly; at the other end, deletions of chromosomes have been found to be related to schizophrenia and microcephaly.

Environmental events associated with macrocephaly include infection, neonatal intraventricular hemorrhage (bleeding within the infant brain), subdural hematoma (bleeding beneath the outer lining of the brain), subdural effusion (collection of fluid beneath the outer lining of the brain), and arachnoid cysts (cysts on the brain surface).

Synostosis (plural: synostoses) is fusion of two bones. It can be normal in puberty, fusion of the epiphysis, or abnormal. When synostosis is abnormal it is a type of dysostosis.

Examples of synostoses include:

- craniosynostosis – an abnormal fusion of two or more cranial bones;

- radioulnar synostosis – the abnormal fusion of the radius and ulna bones of the forearm;

- tarsal coalition – a failure to separately form all seven bones of the tarsus (the hind part of the foot) resulting in an amalgamation of two bones; and

- syndactyly – the abnormal fusion of neighboring digits.

Synostosis within joints can cause ankylosis.

Radioulnar synostosis is one of the more common failures of separation of parts of the upper limb. There are two general types: one is characterized by fusion of the radius and ulna at their proximal borders and the other is fused distal to the proximal radial epiphysis. Most cases are sporadic, congenital (due to a defect in longitudinal segmentation at the 7th week of development) and less often post-traumatic, bilateral in 60%, and more common in males. Familial cases in association with autosomal dominant transmission appear to be concentrated in certain geographic regions, such as Sicily.

The condition frequently is not noted until late childhood, as function may be normal, especially in unilateral cases. Increased wrist motion may compensate for the absent forearm motion. It has been suggested that individuals whose forearms are fixed in greater amounts of pronation (over 60 degrees) face more problems with function than those with around 20 degrees of fixation. Pain is generally not a problem, unless radial head dislocation should occur.

Most examples of radioulnar synostosis are isolated (non-syndromic). Syndromes that may be accompanied by radioulnar synostosis include X chromosome polyploidy (e.g., XXXY) and other chromosome disorders (e.g., 4p- syndrome, Williams syndrome), acrofacial dysostosis, Antley–Bixler syndrome, genitopatellar syndrome, Greig cephalopolysyndactyly syndrome, hereditary multiple osteochondromas (hereditary multiple exostoses), limb-body wall complex, and Nievergelt syndrome.

Craniosynostosis (from cranio, cranium; + syn, together; + ostosis relating to bone) is a condition in which one or more of the fibrous sutures in an infant skull prematurely fuses by turning into bone (ossification). Craniosynostosis has following kinds: scaphocephaly, trigonocephaly, plagiocephaly, anterior plagiocephaly, posterior plagiocephaly, brachycephaly, oxycephaly, pansynostosis.

There is currently no cure for FD and death occurs in 50% of the affected individuals by age 30. There are only two treatment centers, one at New York University Hospital and one at the Sheba Medical Center in Israel. One is being planned for the San Francisco area.

The survival rate and quality of life have increased since the mid-1980s mostly due to a greater understanding of the most dangerous symptoms. At present, FD patients can be expected to function independently if treatment is begun early and major disabilities avoided.

A major issue has been aspiration pneumonia, where food or regurgitated stomach content would be aspirated into the lungs causing infections. Fundoplications (by preventing regurgitation) and gastrostomy tubes (to provide nonoral nutrition) have reduced the frequency of hospitalization.

Other issues which can be treated include FD crises, scoliosis, and various eye conditions due to limited or no tears.

An FD crisis is the body's loss of control of various autonomic nervous system functions including blood pressure, heart rate, and body temperature. Both short-term and chronic periodic high or low blood pressure have consequences and medication is used to stabilize blood pressure.

Although the FD-causing gene has been identified and it seems to have tissue specific expression, there is no definitive treatment at present.

Treatment of FD remains preventative, symptomatic and supportive. FD does not express itself in a consistent manner. The type and severity of symptoms displayed vary among patients and even at different ages on the same patients. So patients should have specialized individual treatment plans. Medications are used to control vomiting, eye dryness, and blood pressure. There are some commonly needed treatments including:

1. Artificial tears: using eye drops containing artificial tear solutions (methylcellulose)

2. Feeding: Maintenance of adequate nutrition, avoidance of aspiration; thickened formula and different shaped nipples are used for baby.

3. Daily chest physiotherapy (nebulization, bronchodilators, and postural drainage): for Chronic lung disease from recurrent aspiration pneumonia

4. Special drug management of autonomic manifestations such as vomiting: intravenous or rectal diazepam (0.2 mg/kg q3h) and rectal chloral hydrate (30 mg/kg q6h)

5. Protecting the child from injury (coping with decreased taste, temperature and pain perception)

6. Combating orthostatic hypotension: hydration, leg exercise, frequent small meals, a high-salt diet, and drugs such as fludrocortisone.

7. Treatment of orthopedic problems (tibial torsion and spinal curvature)

8. Compensating for labile blood pressures

There is no cure for Familial Dysautonomia.

Acne treatment may require oral tetracycline antibiotics or isotretinoin. Treatments directed at tumor necrosis factor (TNF) (infliximab, etanercept) and interleukin-1 (anakinra) have shown a good response in resistant arthritis and pyoderma gangrenosum. Other traditional immunosuppressant treatments for arthritis or pyoderma gangrenosum may also be used.

Oligodactyly (from the Ancient Greek "oligos" meaning "few" and δάκτυλος "daktylos" meaning "finger") is the presence of fewer than five fingers or toes on a hand or foot.

It is quite often incorrectly called "hypodactyly", but the Greek prefixes and are used for scales (e.g. in hypoglycaemia and hypercholesterolemia). This as opposed to or scales, where and should be used (e.g. in oligarchy and polygamy). Oligodactyly is therefore the opposite of polydactyly. Very rare, this medical condition usually has a genetic or familial cause.

Oligodactyly is sometimes a sign or symptom of several syndromes including Poland syndrome and Weyer Ulnar Ray Syndrome. It is a type of Dysmelia.

Ectrodactyly is an extreme instance of oligodactyly, involving the absence of one or more central digits of the hand or foot and is also known as split hand/split foot malformation (SHFM). The hands and feet of people with ectrodactyly are often described as "claw-like" and may include only the thumb and one finger (usually either the little finger, ring finger, or a syndactyly of the two) with similar abnormalities of the feet.

People with oligodactyly often have full use of the remaining digits and adapt well to their condition. They are not greatly hindered in their daily activities, if at all. Even those with the most extreme forms are known to engage in tasks that require fine control, such as writing and bootmaking as well as working as a cab driver.

Vadoma people of Zimbabwe have a high frequency of oligodactyly.

Treatment:wide excision taking 8mm normal tissue as this is locally malignant. For recurrence radiotherapy is given

Bone marrow transplant may be possible for Severe Combined Immune Deficiency and other severe immunodeficiences.

Virus-specific T-Lymphocytes (VST) therapy is used for patients who have received hematopoietic stem cell transplantation that has proven to be unsuccessful. It is a treatment that has been effective in preventing and treating viral infections after HSCT. VST therapy uses active donor T-cells that are isolated from alloreactive T-cells which have proven immunity against one or more viruses. Such donor T-cells often cause acute graft-versus-host disease (GVHD), a subject of ongoing investigation. VSTs have been produced primarily by ex-vivo cultures and by the expansion of T-lymphocytes after stimulation with viral antigens. This is carried out by using donor-derived antigen-presenting cells. These new methods have reduced culture time to 10–12 days by using specific cytokines from adult donors or virus-naive cord blood. This treatment is far quicker and with a substantially higher success rate than the 3–6 months it takes to carry out HSCT on a patient diagnosed with a primary immunodeficiency. T-lymphocyte therapies are still in the experimental stage; few are even in clinical trials, none have been FDA approved, and availability in clinical practice may be years or even a decade or more away.

The treatment of primary immunodeficiencies depends foremost on the nature of the abnormality. Somatic treatment of primarily genetic defects is in its infancy. Most treatment is therefore passive and palliative, and falls into two modalities: managing infections and boosting the immune system.

Reduction of exposure to pathogens may be recommended, and in many situations prophylactic antibiotics or antivirals may be advised.

In the case of humoral immune deficiency, immunoglobulin replacement therapy in the form of intravenous immunoglobulin (IVIG) or subcutaneous immunoglobulin (SCIG) may be available.

In cases of autoimmune disorders, immunosuppression therapies like corticosteroids may be prescribed.

People with FHM are encouraged to avoid activities that may trigger their attacks. Minor head trauma is a common attack precipitant, so FHM sufferers should avoid contact sports. Acetazolamide or standard drugs are often used to treat attacks, though those leading to vasoconstriction should be avoided due to the risk of stroke.
