Abstract

Audiometric evaluations were made for cats which were undergoing TM regeneration. For a one month period of regrowth and testing, there was an improvement in thresholds over the range of frequencies which were tested and the final evaluations (complete TM regrown) indicated greater auditory deficits in the high frequencies. The greater high frequency losses started at 1 to 2 kHz. and increased with frequency. The pattern of greater high frequency loss is thought to result from the fact that the regrown TMs did not adhere to the manubrium, but rather grew straight from the fibrous annulus and formed a flat rather than conical membrane.

摘要

对正在进行鼓膜再生的猫进行了听力测试评估。在为期一个月的再生和测试期间,在所测试的频率范围内阈值有所改善,最终评估(鼓膜完全再生)表明高频听力损失更大。更大的高频损失从1至2千赫兹开始,并随频率增加。高频损失更大的模式被认为是由于再生的鼓膜没有附着在锤骨柄上,而是直接从纤维环生长并形成了一个扁平而非圆锥形的膜。
