There is no causative / curative therapy. Symptomatic medical treatments are focussing on symptoms caused by orthopaedic, dental or cardiac problems. Regarding perioperative / anesthesiological management, recommendations for medical professionals are published at OrphanAnesthesia.

Similar to all genetic diseases Aarskog–Scott syndrome cannot be cured, although numerous treatments exist to increase the quality of life.

Surgery may be required to correct some of the anomalies, and orthodontic treatment may be used to correct some of the facial abnormalities. Trials of growth hormone have been effective to treat short stature in this disorder.

Some people may have some mental slowness, but children with this condition often have good social skills. Some males may have problems with fertility.

Like treatment options, the prognosis is dependent on the severity of the symptoms. Despite the various symptoms and limitations, most individuals have normal intelligence and can lead a normal life.

Because kniest dysplasia can affect various body systems, treatments can vary between non-surgical and surgical treatment. Patients will be monitored over time, and treatments will be provided based on the complications that arise.

Due to its mild presentation, MAIS often goes unnoticed and untreated. Management of MAIS is currently limited to symptomatic management; methods to correct a malfunctioning androgen receptor protein that result from an AR gene mutation are not currently available. Treatment includes surgical correction of mild gynecomastia, minor hypospadias repair, and testosterone supplementation. Supraphysiological doses of testosterone have been shown to correct diminished secondary sexual characteristics in men with MAIS, as well as to reverse infertility due to low sperm count. As is the case with PAIS, men with MAIS will experience side effects from androgen therapy (such as the suppression of the hypothalamic-pituitary-gonadal axis) at a higher dosage than unaffected men. Careful monitoring is required to ensure the safety and efficacy of treatment. Regular breast and prostate examinations may be necessary due to comorbid association with breast and prostate cancers.

Congenital anomalies like cryptorchidism, renal agenesis/dysplasia, musculoskeletal and cardiopulmonary anomalies are also common (>50% cases), hence evaluation of the patient for internal anomalies is mandatory.

Although aphallia can occur in any body type, it is considered a substantially more troublesome problem with those who have testes present, and has in the past sometimes been considered justification for assigning and rearing a genetically male infant as a girl. After the theory in the 1950s that gender as a social construct was purely nurture and so an individual child could be raised early on and into one gender or the other regardless of their genetics or brain chemistry. Intersex people generally advocate harshly against coercive genital reassignment however, and encourage infants to be raised choosing their own gender identity. The nurture theory has been largely abandoned and cases of trying to rear children this way have not proven to be successful transitions.

In newborn period or infancy, feminizing operations are recommended for treatment of penile agenesis, but after 2 years, as sexual identification of the patients has appeared, it is advised to perform masculinizing operations in order not to disturb the child psychologically.

Recent advances in surgical phalloplasty techniques have provided additional options for those still interested in pursuing surgery.

MRI will help with the diagnosis of structural abnormality of the brain. Genetic testing may also be pursued.

Endodontic intervention can help conserve the existing health of affected permanent teeth. It is difficult to perform an endodontic therapy on teeth that develop abscesses as a resultant of obliteration of the pulp chambers and root canals. An alternative to conventional therapy would be retrograde filling and periapical curettage. However, these therapies are not recommended for teeth with roots that are too short.

Teeth with short thin roots and marked cervical constrictions are less favourable for indirect restorations such as crown placements. If endodontics treatment fails, and abscess develops around the root apex, extraction of the affected teeth would be the best treatment option. Dentures or over dentures can be considered, as rehabilitation until growth is completed. Cast partial dentures could also be an alternative treatment option and it only works if there are a few teeth that has enough root length to serve as retentive purpose.

Colobomas of the iris may be treated in a number of ways. A simple cosmetic solution is a specialized cosmetic contact lens with an artificial pupil aperture. Surgical repair of the iris defect is also possible. Surgeons can close the defect by stitching in some cases. More recently artificial iris prosthetic devices such as the Human Optics artificial iris have been used successfully by specialist surgeons. This device cannot be used if the natural lens is in place and is not suitable for children. Suture repair is a better option where the lens is still present.

Vision can be improved with glasses, contact lenses or even laser eye surgery but may be limited if the retina is affected or there is amblyopia.

There is no treatment, but because this is a benign condition with no serious clinical complications, prognosis is excellent.

Treatment in fibrous dysplasia is mainly palliative, and is focused on managing fractures and preventing deformity. There are no medications capable of altering the disease course. Intravenous bisphosphonates may be helpful for treatment of bone pain, but there is no clear evidence that they strengthen bone lesions or prevent fractures. Surgical techniques that are effective in other disorders, such as bone grafting, curettage, and plates and screws, are frequently ineffective in fibrous dysplasia and should be avoided. Intramedullary rods are generally preferred for management of fractures and deformity in the lower extremities. Progressive scoliosis can generally be managed with standard instrumentation and fusion techniques. Surgical management in the craniofacial skeleton is complicated by frequent post-operative FD regrowth, and should focus on correction of functional deformities. Prophylactic optic nerve decompression increases the risk of vision loss and is contraindicated.

Managing endocrinopathies is a critical component of management in FD. All patients with fibrous dysplasia should be evaluated and treated for endocrine diseases associated with McCune–Albright syndrome. In particular untreated growth hormone excess may worsen craniofacial fibrous dysplasia and increase the risk of blindness. Untreated hypophosphatemia increases bone pain and risk of fractures.

Osteofibrous dysplasia is treated with marginal resection with or without bone grafting, depending on the size of the lesion and the extent of bony involvement. However, due to the high rate of recurrence in skeletally immature individuals, this procedure is usually postponed until skeletal maturity.

In utero exposure to cocaine and other street drugs can lead to septo-optic dysplasia.

Early hip dysplasia can often be treated using a Pavlik harness (see photograph) or the Frejka pillow/splint in the first year of life with usually normal results. Complications can occur when using the Pavlik Harness. Cases of Femoral Nerve Palsy and Avascular Necrosis of the femoral head have been reported with the use of the Pavlik harness, but whether these cases were due to improper application of the device or a complication encountered in the course of the disorder remains unresolved. Complications arise mainly because the sheet of the iliopsoas muscle pushes circumflex artery against the neck of the femur and decreases blood flow to the femoral head, so the Frejka pillow is not indicated in all the forms of the developmental dysplasia of the hip.

Other devices employed include the spica cast, particularly following surgical closed reduction, open reduction, or osteotomy in babies and young children. Traction is sometimes used in the weeks leading up to a surgery to help stretch ligaments in the hip joint, although its use is controversial and varies amongst physicians.

In older children the adductor and iliopsoas muscles may have to be treated surgically because they adapt to the dislocated joint position (contracture).

Braces and splints are often used following either of these methods to continue treatment.

Although some children "outgrow" untreated mild hip dysplasia and some forms of untreated dysplasia cause little or no impairment of quality of life, studies have as yet been unable to find a method of predicting outcomes. On the other hand, it has often been documented that starting treatment late leads to complications and ends in poor results.

Robinow syndrome is an extremely rare genetic disorder characterized by short-limbed dwarfism, abnormalities in the head, face, and external genitalia, as well as vertebral segmentation. The disorder was first described in 1969 by human geneticist Meinhard Robinow, along with physicians Frederic N. Silverman and Hugo D. Smith, in the "American Journal of Diseases of Children". By 2002, over 100 cases had been documented and introduced into medical literature.

Two forms of the disorder exist, dominant and recessive, of which the former is more common. Patients with the dominant version often suffer moderately from the aforementioned symptoms. Recessive cases, on the other hand, are usually more physically marked, and individuals may exhibit more skeletal abnormalities. The recessive form is particularly frequent in Turkey. However, this can likely be explained by a common ancestor, as these patients' families can be traced to a single town in Eastern Turkey. Clusters of the autosomal recessive form have also been documented in Oman and Czechoslovakia.

The syndrome is also known as Robinow-Silverman-Smith syndrome, Robinow dwarfism, fetal face, fetal face syndrome, fetal facies syndrome, acral dysostosis with facial and genital abnormalities, or mesomelic dwarfism-small genitalia syndrome. The recessive form was previously known as Covesdem syndrome.

Pacman dysplasia (alternatively known as epiphyseal stippling with osteoclastic hyperplasia) is a lethal autosomal recessive skeletal dysplasia. The dysplasia is present during fetal development.

"In utero" sonographic diagnosis is possible when characteristic features such as bilateral bowed femurs and tibia, clubbed feet, prominent curvature of the neck, a bell-shaped chest, pelvic dilation, and/or an undersized jaw are apparent

Radiographic techniques are generally used only postnatally and also rely on prototypical physical characteristics.

Non-surgical interventions include three elements: weight control, exercise control, and medication. Canine massage may alleviate discomfort and help move lymph and nutrients through the system. Weight control is often "the single most important thing that we can do to help a dog with arthritis", and consequentially "reducing the dog's weight is enough to control all of the symptoms of arthritis in many dogs". Reasonable exercise stimulates cartilage growth and reduces degeneration (though excessive exercise can do harm too), and also regular long walks in early or mild dysplasia can help prevent loss of muscle mass to the hips. Medication can reduce pain and discomfort, and also reduce damaging inflammation.

Non-surgical intervention is usually via a suitable non-steroidal anti-inflammatory drug (NSAID) which doubles as an anti-inflammatory and painkiller. Typical NSAIDs used for hip dysplasia include carprofen and meloxicam (often sold as Rimadyl and Metacam respectively), both used to treat arthritis resulting from dysplasia, although other NSAIDs such as tepoxalin (Zubrin) and prednoleucotropin ("PLT", a combination of cinchophen and prednisolone) are sometimes tried. NSAIDs vary dramatically between species as to effect: a safe NSAID in one species may be unsafe in another. It is important to follow veterinary advice.

A glucosamine-based nutritional supplement may give the body additional raw materials used in joint repair. Glucosamine can take 3–4 weeks to start showing its effects, so the trial period for medication is usually at least 3–5 weeks. In vitro, glucosamine has been shown to have negative effects on cartilage cells.

It is also common to try multiple anti-inflammatories over a further 4–6 week period, if necessary, since an animal will often respond to one type but fail to respond to another. If one anti-inflammatory does not work, a vet will often try one or two other brands for 2–3 weeks each, also in conjunction with ongoing glucosamine, before concluding that the condition does not seem responsive to medication.

Carprofen, and other anti-inflammatories in general, whilst very safe for most animals, can sometimes cause problems for some animals, and (in a few rare cases) sudden death through liver toxicity. This is most commonly discussed with carprofen but may be equally relevant with other anti-inflammatories. As a result, it is often recommended to perform monthly (or at least, twice-annually) blood tests to confirm that the animal is not reacting adversely to the medications. Such side effects are rare but worth being aware of, especially if long-term use is anticipated.

This regimen can usually be maintained for the long term, as long as it is effective in keeping the symptoms of dysplasia at bay.

Some attempts have been made to treat the pain caused by arthritic changes through the use of "laser therapy", in particular "class IV laser therapy". Well-controlled clinical trials are unfortunately lacking, and much of the evidence for these procedures remains anecdotal.

Aphallia is a congenital malformation in which the phallus (penis or clitoris) is absent. It is the female counterpart of penile agenesis and testicular agenesis. The word is derived from the Greek "a-" for "not", and "phallos" for "penis". It is classified as an intersex condition.

People with ED often have certain cranial-facial features which can be distinctive: frontal bossing is common, longer or more pronounced chins are frequent, broader noses are also very common. In some types of ED, abnormal development of parts of the eye can result in dryness of the eye, cataracts, and vision defects. Professional eye care can help minimize the effects of ED on vision. Similarly, abnormalities in the development of the ear may cause hearing problems. Respiratory infections can be more common because the normal protective secretions of the mouth and nose are not present. Precautions must be taken to limit infections.

The development of tooth buds frequently results in congenitally absent teeth (in many cases a lack of a permanent set) and/or in the growth of teeth that are peg-shaped or pointed. The enamel may also be defective. Cosmetic dental treatment is almost always necessary and children may need dentures as early as two years of age. Multiple denture replacements are often needed as the child grows, and dental implants may be an option in adolescence, once the jaw is fully grown. Nowadays the option of extracting the teeth and substituting them with dental implants is quite common. In other cases, teeth can be crowned. Orthodontic treatment also may be necessary. Because dental treatment is complex, a multi-disciplinary approach is best.

Malformations can be congenital. They are classified by location of the malformation, such as uterine malformation.
