CONCLUSION
The transcanal approach could be an effective and time-saving method for selected cochlear implantation (CI) candidates.
OBJECTIVE
This study was designed to introduce the method of CI via the transcanal approach used in patients with abnormal temporal bone structure or chronic otitis media (COM).
METHODS
The medical records of six patients who underwent CI via the transcanal approach were reviewed retrospectively. The electrode was inserted through the external auditory canal (EAC) after tympanomeatal flap elevation and cochleostomy.
RESULTS
Three patients had a history of inactive COM. In the remaining patients, cochleostomy via the transmastoid approach was difficult due to aberrant anatomic structures such as vascular anomaly, narrow aditus, and anteriorly displaced sigmoid sinus. All patients underwent CI via the transcanal approach successfully. There was no serious complication postoperatively.
结论
经耳道入路对于部分人工耳蜗植入（CI）候选者可能是一种有效且节省时间的方法。
目的
本研究旨在介绍经耳道入路对颞骨结构异常或慢性中耳炎（COM）患者进行人工耳蜗植入的方法。
方法
回顾性分析6例经耳道入路行人工耳蜗植入患者的病历资料。在掀起鼓室鼓膜瓣并进行耳蜗造瘘后，将电极经外耳道（EAC）插入。
结果
3例患者有非活动性慢性中耳炎病史。其余患者因血管异常、鼓窦入口狭窄、乙状窦前移等解剖结构异常，经乳突入路进行耳蜗造瘘困难。所有患者均成功经耳道入路行人工耳蜗植入。术后无严重并发症。
