OBJECTIVE
To investigate the effect of noise generated by the otologic drills and suctions on the cochlear of the operated and nonoperated ear.
METHOD
To examine the noise generated by the different kind of drills and suctions in tympanoplasty, the ND10 Sound Level Meter (Beijing) was used. The bone-conduction thresholds was measured before and one month after operation respectively in both ears.
RESULTS
Sound pressure levels for the otologic drills and suctions were 82-106 dB and 71-84 dB, respectively. There was no statistically significant difference between pre-noise and one-month post-noise bone-conduction thresholds in both operated and nonoperated ears.
CONCLUSION
It is safety to use otologic drills and suctions for the patients. There is no apparent harmful effect on the function of cochlear in both ears for the noise of using drills and suctions in tympanoplasty.
目的
探讨耳科钻和吸引器产生的噪声对手术耳及非手术耳耳蜗的影响。
方法
使用ND10声级计（北京）检测鼓室成形术中不同类型钻和吸引器产生的噪声。分别于术前及术后1个月测量双耳的骨导阈值。
结果
耳科钻和吸引器的声压级分别为82 - 106 dB和71 - 84 dB。手术耳和非手术耳在噪声暴露前和噪声暴露后1个月的骨导阈值之间无统计学显著差异。
结论
对患者使用耳科钻和吸引器是安全的。鼓室成形术中使用钻和吸引器产生的噪声对双耳耳蜗功能无明显有害影响。
