摘要 为了解决先天性耳道闭锁重度传导性聋的生理缺陷,开展耳道—鼓室成形、异种异体听骨链重建术。4例先天性耳道闭锁,3例伴中耳畸形和耳廓缺如,1例伴中耳畸形和悬雍垂畸形。术中见鼓室狭小,鼓膜缺如,代之坚硬骨板,听骨链严重畸形,面神经走行明显变异,中颅窝硬脑膜下垂,乙状窦前移。在手术显微镜下行乳突轮廓化;重建鼓室、耳道;钛质听骨重建听骨链;移植筋膜行鼓膜成形。术后随访46~164日,听力较术前提高20~45dB。就手术适应证,术中面神经保护及听骨链重建进行讨论。 In order to resolve conduction hearing loss of the patients with congenital malformation of ear, We perform the ear canal - tympanoplasty on 14 cases. The results demonstrated that the hearing of the patients was improved, of wich the hearing of all cases did increase 20 - 45 dB and recover to available level. A long - term follow - up showed that patients had kept the same hearing level as that immediately after surgry.
