Sweep-frequency Bekesy tracings, both forward (low to high frequency) and reverse (high to low frequency), as well as fixed-frequency tracings, were obtained from 18 patients who had eighth-nerve tumors (subsequently confirmed surgically). In general, reverse-sweep frequency tracings revealed greater adaptation for continuous tone stimuli than did forward-sweep frequency tracings. However, if a search for excess adaptation (greater than 20 dB) is the sole purpose for administering Bekesy audiometry to a given patient, then fixed-frequency tracings yield adequate differential information.

Hearing loss, tinnitus, and vertigo have long been associated with Paget's disease of the bone. We reviewed the records of 463 patients with Paget's disease who were seen in the otolaryngology department. Hearing loss was common. It was our observation that mixed hearing losses were part of the disease process. Sensorineural hearing loss was the most frequent loss, but it usually was not part of the disease process. Tinnitus, vertigo, or both were seen in about 20% of these patients.
