目的：评估北美外科医生当前鼓阶人工耳蜗植入手术技术。材料：向参加加拿大多伦多 2006 年 William House 人工耳蜗植入研究小组的所有人工耳蜗植入外科医生进行了一项调查。参与者被要求匿名透露他们的常规手术实践。以多项选择的方式使用经面部隐窝接近圆窗和耳蜗岬的图像来评估外科医生的典型暴露和耳蜗造口位置。返回的调查问卷以电子方式进行处理和评估。结果：73 项返回的调查中有 55 项 (75%) 具有足够的数据有效性和可用性。地标识别和首选的耳蜗造口位置差异很大。大约 20% 的外科医生选择了优于圆窗膜的耳蜗造口位置。耳蜗造口术的大小和位置似乎受到手术经验以及圆窗悬突是否被钻掉的影响。结论：这项调查清楚地记录了鼓阶耳蜗植入手术技术的显着差异。未来的研究应该更清楚地定义该区域的手术解剖结构，以便适当放置鼓阶耳蜗造口术。这些发现可能最终对听力和神经保护人工耳蜗植入手术产生影响。
Objective: To assess current surgical techniques for scala tympani cochlear implantation among North American surgeons.Material: A survey was distributed to all cochlear implant surgeons participating in the 2006 William House Cochlear Implant Study Group in Toronto, Canada. Participants were asked to anonymously identify their routine surgical practices. Images of trans-facial recess approaches to the round window and cochlear promontory were used in a multiple-choice fashion to assess the surgeon's typical exposure and cochleostomy location. Returned questionnaires were electronically processed and evaluated.Results: Fifty-five (75%) of 73 returned surveys had adequate data validity and availability. Landmark identification and preferred cochleostomy locations varied greatly. About 20% of surgeons selected cochleostomy locations superior to the round window membrane. Cochleostomy size and location appeared to be influenced by surgical experience and whether or not the round window overhang was drilled off.Conclusion: This survey clearly documents marked variations in surgical techniques for scala tympani cochlear implantation. Future studies should more clearly define the surgical anatomy of this region for appropriate placement of a scala tympani cochleostomy. These findings may ultimately have an impact on hearing and neural preservation cochlear implant surgeries.
