Goldenhar's Syndrome: Congenital Hearing Deficit of Conductive or Sensorineural Origin? Temporal Bone Histopathologic Study

Abstract

These histopathologic findings appear to confirm the conductive component of the congenital hearing deficit, but a sensorineural component could not be omitted. The ear alterations favor early developmental field defects. The causes of this condition are controversial. Recent results in genetic research pertaining to the MSX class genes permit better understanding of the variety, variability, and different degrees of severity of the anomalies described here.
