Abstract
OBJECTIVE: A new large family with the BOR syndrome is reported with special reference to the presence of a widened vestibular aqueduct and a progressive sensorineural component in the mixed hearing loss. A review of the BOR literature of 184 patients is given. Setting: University Hospitals. RESULTS: A BOR family with 17 affected members was studied. Fourteen of those 17 were still alive and 12 of those cooperated in this clinical study. Detailed radiological studies showed in three out of 12 affected family members a widened vestibular aqueduct and progressive sensorineural hearing loss. This raises the question whether there is a true correlation or whether those are coincidental. CONCLUSION: In our family with the Branchio-Oto-Renal syndrome, a widened vestibular aqueduct and progressive hearing loss is found in a few affected family members. Imaging of the temporal bones and long-term audiometric follow-up could help to reveal whether the widened vestibular aqueduct is the cause for the progressive hearing loss.
