Acoustic Reflex Thresholds in Normal, Cochlear, and Retrocochlear lesions.
Navid Shahnaz
Abstract:   (11264 Views)
The cut off points of 90th percentile of acoustic reflex thresholds were determined in the normal and sensory hearing loss.All subjects had measurable hearing(ANSI-1969≤110 dBHL) in three frequencies of 500,1000 and 2000Hz.While hearing loss was more than 55dB, The cut off point was higher in studies that NR responses was included.In cases that hearing loss was less than 75dB  90th percentile can be used in diganosis of retrochochlear lesions.Since Acoustic reflexes are absent in both mentioned pathologies in greater amount of hearing loss,It would be less efficient in diffrential diganisis of cochlear and retrochochlear lesions to use acoustic reflex thresholds under the mentioned circumstances.

Keywords: Acoustic reflex threshold, cochlear lesions, Retrocochlear pathology
