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 solve the physiological defects of congenital ear canal atresia with severe conduction deafness, ear canal-tympanoplasty and heterotopic allograft reconstruction were performed. 4 cases of congenital ear canal atresia, 3 cases with middle ear deformity and auricle absent, 1 case with middle ear deformity and uvula deformity. Surgery, see the tympanic small tympanic membrane absent, replaced by hard bone plate, serious deformity of the ossicular chain, facial nerve walk obvious variability, the middle fossa dural prolapse, sigmoid sinus. Mastoid contour under the operating microscope; rebuild the tympanic cavity, ear canal; titanium bone reconstruction ossicular chain; transplant fascia line tympanoplasty. Postoperative follow-up 46 to 164 days, hearing improvement than preoperative 20 ~ 45dB. The surgical indications, intraoperative facial nerve protection and ossicular chain reconstruction are discussed.
