目的：对迷路骨化与内耳畸形患者进行听力康复。方法：人工耳蜗植入术。结果：术中发现内耳迷路骨化与先天性内耳畸形各１例。其中，迷路骨化继发于分娩后未定病因，术中见单侧前庭和耳蜗广泛骨化，后将耳蜗电有植入对侧未骨化的耳蜗；先天天性内耳畸形呈鼓岬骨质增厚，圆窗和卵圆窗骨性封闭并增厚，基底转起始部鼓阶扩张，予成功植入耳蜗电极。结论：人工耳蜗植入术中迷路骨化耳畸形时，应根据具体情况采取适当的措施，以保证手术取

MANAGEMENT OF OBLITERATION AND CONGENITAL MALFORMATION OF COCHLEA IN COCHLEAR IMPLANTATION

Objective:To study cochlear implantation in patients with cochlearobliteration or malformation. Methods: Cochlear implantation. Results: Two profound hearing loss patients, including one postlingually deaf adult female with left labyrinthine ossification .due to uncertain causes and one 13-year-old boy with congenital malformation of the cochlea underwent implantation of the Nucleus 22-Channel Cochlea and achieved greatly significant improvment in speech understanding. Labyrinthine ossification and malformation of the cochlea both were found during the operation. The paper presents the findings and manngement of both in the operation. Chncluion: Cochlear implantation can be successsully practised in patientswith cochlear obliteration or malformation.
