It has been suggested that there is a branchial arch development issue late in the first trimester.An increase in Goldenhar syndrome in the children of Gulf War veterans has been suggested, but the difference was shown to be statistically insignificant. Diagnosis
Diagnosis is based on clinical features. General features include unilateral facial asymmetry. Ocular abnormalities include limbal dermoids and strabismus. Otorhinolaryngological features include microtia, partial to complete atresia of external acoustic meatus, preauricular skin tags, deafness, and macrosomia. Skeletal abnormalities include mandibular deformities, scoliosis. Other organ abnormalities include cardiac defects and renal abnormalities. Treatment
Treatment is usually confined to such surgical intervention as may be necessary to help the child to develop e.g. jaw distraction/bone grafts, ocular dermoid debulking (see below), repairing cleft palate/lip, repairing heart malformations or spinal surgery. Some patients with Goldenhar syndrome will require assistance as they grow by means of hearing aids or glasses. Stem cell grafting (womb tissue grafting) has been successfully used to "reprogram" eye dermoids, effectively halting the regrowth of eye dermoids. These tissues that grow on the eye are "mis-programmed" cells (sometimes tooth or nail cells instead of eye cells). Epidemiology
Prevalence ranges from 1 in 3,500 to 5,600 live births. Male-female ratio is found to be 3:2. Eponym
The condition was documented in 1952 by Belgian–American ophthalmologist Maurice Goldenhar (1924–2001). References
