ABSTRACT
Objective To explore the characte ristics of pure tone threshold (PTT) in auditory neuropathy. Methods The results of PTT audiometry were analysed in 48 patients with auditory neuropathy and compared with that of cochlear deafness. Results PTT audiograms in auditory neuropathy group r evealed curves including ascending slope, peak, spoon, letter W, lain letter S, flat, gentle slope. Binaural symmetric PTT audiograms were seen in 38 cases and asymmetric in 10 cases. The auditory threshold in auditory neuropathy showed a e levated range from mild to moderate degrees. Elevated degrees of auditory thresh old in left and right ears were consistent. The elevations of low-frequency audi tory threshold or in the main feature of low-frequency auditory threshold were 9 3.75% (90/96 ears) in the PTT audiograms. Conclusion The elevations of biauricular symmetric and ba sic symmetric low-frequency auditory threshold or in the main feature of low-fre quency auditory threshold were important characteristics of auditory neuropathy.
