| 摘 要： | 目的 :探讨耳显微外科手术中电钻及吸引的噪声 ,对术耳和非术耳的耳蜗功能所产生的影响。方法 :采用ND10型声级计 ,对鼓室成形术中不同规格和不同种类的钻头及吸引所产生的噪声进行检测 ,并分别比较术耳术前和术后 1个月的纯音骨导阈值以及非术耳术前和术后 1个月的骨导阈值。结果 :术中电钻钻头与吸引所致噪声强度分别为 82～ 10 6dB(A)和 71～ 84dB(A) ,术前与术后 1个月左右双耳纯音骨导阈值变化差异无统计学意义 (P >0 .0 5 )。结论 :鼓室成形术中电钻及吸引器的使用是安全的 ,对双侧耳蜗功能无明显不良影响 |

| Abstract: | 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. |
