Discussion

The combination of several features such as micro- tia, hemifacial microsomia, lateral facial cleft, epibulbar dermoid and upper eye lid coloboma is described as oculo-auriculo-vertebral spectrum (OAV).[1] The pres- ence of otic hypoplasia, lateral facial cleft and vertebral Figure 1: Shows the left sided facial paralysis anomalies are the minimum criteria for the diagnosis of Goldenhar syndrome. The incidence of Goldenhar syn- drome is extremely rare.[3] The etiology is not known, but is thought to be due to exposure to viruses or chemi- cals during pregnancy, due to abnormal vascular sup- ply to the first arch and abnormality of mesoblastic de- velopment affecting the formation of vertebral and bran- chial systems.[4] Some researchers suggest that the dis- order may be due to interaction of many genes with environmental factors (multifactorial inheritance).[4-6] Approximately 5000 children are born every year in United States with significant hearing impairment.[1] Goldenhar syndrome associated with deafness is rare and in most cases it occurs randomly without any ap- parent cause. Most cases are sporadic, but family his- tory was also observed in certain cases. Individuals af- fected in successive generations have been observed.[7- Figure 2: Shows right Perilimbal dermoid cyst 8] The ear anomalies include external ear tags and aural fistulae.[9-14] In this case, the child showed malformation ricle in the left preauricular region. of the pinna associated with meatal atresia and auricu- X-ray of the chest showed revealed cardiomegaly, lar tags bilaterally.
