All patients had imaging evaluation by magnetic resonance imaging and molecular screening for the genes SHH, GLI2, and SIX3. Each patient underwent clinical (otological and vestibular antecedents, otoscopy) and instrumental (tympanometry, auditory brainstem response--ABR) evaluation to compare hearing and...
