Sensorineural Loss

Tone decay was assessed by the Bekesy and modified Rosenberg procedures in audiological patients with sensorineural-type loss for whom there was no neurological evidence of retrocochlear pathology. Thirty-five subjects were tested at 500 Hz, 97 at 2000 Hz, and 92 at 4000 Hz. Tone decay tended to increase with increased hearing threshold level for both tests at all three frequencies, with low but significant correlations at two of the three frequencies for each test. There were no systematic differences between the Bekesy and modified Rosenberg procedures with regard to overall level, frequency effects, or hearing threshold effects. A low but significant correlation was obtained between the two procedures at all three frequencies.

AbstractMany acoustic neurinomas and CPA tumours present an audiometric picture of positive-recruitment hearing impairment although often the CMs are not significantly impaired (according to ECochG) and because, even in the case of a small acoustic neuroma, the interpeak latency between wave I and V (ERA) is increased in the majority of cases. Recruitment cannot be explained, in these cases, as an expression of an accompanying vascular inner ear lesion. Therefore, we attempt to interpret the differential audiometric picture to the various patterns of damage of the auditory nerve. The finding of tone decay is seen as an expression of myelin damage corresponding to the hearing loss in multiple sclerosis.The absence of any degree of tone decay excludes an isolated damage of the myelin sheaths; hearing loss then results from a disturbance also of the associated axons. At such a stage, where there is a functional loss to part of the neural fibres but with intact myelinated residual fibres, the result could be the phenomenon of recruitment for suprathreshold stimulation. This theory of selective compression is compared to an isolated efferent lesion theory as the cause for recruitment in AN and CPA tumours.

Details are presented of a case of acoustic neuroma in which there was a discrepancy between Bekesy sweep-frequency results and those of fixed frequency traces and a tone-decay test. A series of Bekesy fixed frequency traces produced the unexpected findings that frequencies at which adaptation does and does not occur can show bizarre patterns; that the difference between adapting and nonadapting frequencies can be quite small; and that adaptation at a given frequency can vary over a short time. It is suggested that more attention be given to Bekesy fixed frequency tracings when adaptation is not displayed in sweep-frequency tracings.
