耳蜗骨化曾经是人工耳蜗植入术的禁忌证,但是耳聋患者中耳蜗骨化发生率高。Trinh等[1]报道105例人工耳蜗植入术(大多数是成人)中14%耳蜗鼓阶骨化。儿童耳蜗骨化发生率更高,Luxford等[2]报道128例儿童中34%耳蜗骨化。如果放弃这些耳蜗骨化患者将使得很多耳聋患者难以回到有声世界,失去语言交流的机会。现报道我院31例耳蜗骨化的全聋患者人工耳蜗植入术中情况和术后人工耳蜗听阈,探讨人工耳蜗植入术在耳蜗骨化患者的可行性。资料与方法一、病例资料1995年5月至2005年7月因双耳重度和极重度感音神经性聋在我科接受人工耳蜗植入术的患者720例,… | | |  推荐 CAJ下载  PDF下载 | | | CAJViewer7.0阅读器支持所有CNKI文件格式，AdobeReader仅支持PDF格式 | | | | Cochlear implantation in patients with ossified cochleas | | | WANG Yi;CAO Ke-li;CHEN Xiao-wei;YANG Hua;SONG Wei;PAN Wei-dong. Department of Otorhinolaryngology;Peking Union Medical College Hospital;Chinese Academy of Medical Sciences and Peking Union Medical College;Beijing 100730;China | | | Objective The ossified cochlea was no longer an absolute contra-indication to cochlear implantation but it was still a challenge even for the experienced otologist.To report the condition of cochlear implantation and the hearing results of 31 cases of cochlear ossification. Methods Retrospective analysis of cochlear implantation of 720 cases of cochlear implantation from May 1995 to July 2005 in Peking Union Medical College Hospital. Results Thirty-one cochlear ossification patients was found from all the 720 surgeries which included 27 mild cases and 4 severe ones, 14 males,17 females.And the age of operation was 1.4～59.0 years old ,mean age was 13.2 years old.All of them had cochlear implanted through mastoid-facial recess.There was no complications during or post the operations.And the hearing threshold was about 40 dB in the sound field,the results were similar to those without cochlear ossification. Conclusions Although it was difficult of cochlear implantation in cochlear ossification patients,but in most cases especially mild ones all the electrodes could be implanted after clearing the ossified tissue,and had few damage to the electrodes. Now it was possible to practice in the partial cochlea ossification.
