Abstract
The hearing impairment associated with congenital external auditory canal atresia has been managed with early bone conduction hearing aid placement and surgical reconstruction in selected patients. However, many patients do not wear a bone conduction hearing aid because of physical or social considerations and surgical reconstruction of the external auditory canal and middle ear may be difficult or contraindicated. This report details the use of implantable bone conducting hearing devices in five children with bilateral external auditory canal atresia. Each patient had bilateral conductive hearing impairment with normal bone conduction thresholds. Four of the five patients had associated craniofacial anomalies including three cases of microtia. The average preoperative sound field speech reception threshold improved from 63 dB to 13 dB with the implant. Patients experienced a definite preference for the implanted hearing device over the bone conduction hearing aid.
