报告行中耳及镫骨手术６０８耳，术后１月内出现骨导下降１０ｄＢ以上７耳，感音性聋发生率达１．１５％。经对产生并发症的原因进行分析认为，术中避免机械能经听骨链传入内耳，人工镫骨手术严格遵循操作常规，避免术中吸引器噪声损伤，都是预防耳蜗损伤所必需的。 The report of middle ear and stapes surgery 608 ears, within 1 month after surgery there was a decrease of more than 10dB bone conduction, sensory hearing loss rate of 1.15%. After analyzing the causes of complication, it is suggested that intraoperative avoidance of mechanical energy transfer to the inner ear via ossicular chain should be followed. Artificial stapes operation strictly follows the routine of operation and avoids intraoperative aspirator noise damage, all of which are necessary to prevent cochlear injury.
