Middle and inner ear malformations in mutation‐proven branchio‐oculo‐facial (BOF) syndrome: Case series and review of the literature

Hearing impairment is common in individuals with branchio‐oculo‐facial (BOF) syndrome. The majority of described individuals have conductive hearing impairment due to malformed ossicles and/or external canal stenosis or atresia, although a sensorineural component to the hearing impairment in BOF syndrome is increasingly being reported. Sophisticated computed tomography (CT) of the temporal bone has revealed middle and inner ear malformations in three previous reports. We present middle and inner ear abnormalities in three additional individuals with mutation‐proven BOF syndrome. We suggest that temporal bone CT imaging be included in the medical workup of a child with BOF syndrome, in order to guide management. © 2012 Wiley Periodicals, Inc.
