متن کاملAir-And Bone-Conduction Auditory Brainstem Response in Children with Congenital External Auditory Canal Atresia
Results: ABR threshold for air and bone conduction were 66.53 ± 7.12 and 12.55 ± 6.96 dBnHL, respectively, in children with congenital EACA, as well as 25.32 ± 2.66 and 10.71 ± 4.51 dBnHL, respectively, in children with normal hearing. The two groups showed statistical difference in air-conduction ABR thresholds. Meanwhile, air–bone ABR threshold gap was greater in children with EACA than in ch...

A 37-year-old female was admittedwith bilateral hearing loss since her childhood. On examination of the case with no other complaint, the EACs were short and closed conically. There was a conductive type of hearing loss at 50 dB in the right ear (air bone gap 40 dB) , and at 47 dB (air bone gap 37dB) in the left ear on the pure tone audiogram. On temporal bone CT, bilateral the EACs were observ...
