Exposure to intense noise has been identified as a potential risk in the development of hearing impairment. Social concern about excessive noise is increasing and this also extends to the operating room. A noise level study was performed in the operating room during mastoidectomy with a sound level meter and it was analyzed by a sound-analyzing program. The drilling instruments used included the Stryker, Midas, M.P.S. and Med-Next. The operator was exposed to sound levels from 69 to 83 dBA. The loudest drilling instrument was the Midas and it produced an average sound level of 83 dBA to the operator. The mean exposure time was 41 minutes during mastoidectomy. This is below the occupational noise-level regulations in Korea. However, considering that individual susceptibility to noise varies and that the otologic surgeon is repeatedly exposed to prolonged drilling noise, ear protection is recommended for the operators of high-speed drilling instruments.
暴露于高强度噪音已被确定为听力损伤发展中的一个潜在风险。社会对过度噪音的关注日益增加，这也延伸到了手术室。在乳突切除术中，使用声级计在手术室进行了噪音水平研究，并通过声音分析程序进行了分析。使用的钻孔器械包括史赛克、美敦力、M.P.S.和Med-Next。操作人员暴露于69至83分贝（A）的声级。最响的钻孔器械是美敦力，它给操作人员产生的平均声级为83分贝（A）。乳突切除术期间的平均暴露时间为41分钟。这低于韩国的职业噪音水平规定。然而，考虑到个体对噪音的易感性不同，且耳科外科医生反复暴露于长时间的钻孔噪音中，建议高速钻孔器械的操作人员佩戴听力保护装置。
