A 36-year-old man presented with a progressive hearing loss in his right ear. He denied drainage, pain, and tinnitus in the affected ear, and he had no history of ear infections. He believed that an uncle had previously undergone an ear operation.
On tuning-fork examination, the Weber test lateralized to the right. With both the 512- and 1,024-Hz tuning forks, bone conduction was greater than air conduction on the right. In the left ear, air conduction was greater than bone conduction.
