Presenting the clinical features and treatment options for incomplete partition type-III.
Nine primary and 1 revision incomplete partition type-III cochlear implant cases treated between 2004 and 2015 in Hacettepe University Department of Otolaryngology were included in the study. Treatment options and particularly cochlear implantation tecnique were described.
Nine primary and 1 revison cases were all succesfully implanted. Eight cases were standart cases with no secondary intervention. Case #9 has to be revised intraoperatively and case #10 were operated four times in another center and revised in our department.
Incomplete partition type-III is one of the rarest inner ear anomaly and the rarest among incomplete partition group. Treatment options may differ depending on the hearing loss level of the patient. Stapes surgery should be avoided because it will lead to gusher and further hearing loss. Preoperative imaging is mandatory in order to avoid unnecessary stapes surgery. Incochlear implantation surgery a gusher and misplacement into the IAC may complicate the surgery. Gusher should be controlled intraoperatively and the position of the electrode should be controlled via intraoperative imaging.
介绍III型不完全分隔的临床特征及治疗选择。
本研究纳入了2004年至2015年在哈杰泰佩大学耳鼻喉科治疗的9例原发性和1例翻修的III型不完全分隔人工耳蜗植入病例。描述了治疗选择，特别是人工耳蜗植入技术。
9例原发性病例和1例翻修病例均成功植入。8例为无需二次干预的标准病例。病例9术中必须进行翻修，病例10在另一个中心接受了4次手术，并在我们科室进行了翻修。
III型不完全分隔是最罕见的内耳畸形之一，也是不完全分隔组中最罕见的。治疗选择可能因患者听力损失程度而异。应避免镫骨手术，因为这会导致脑脊液耳漏和进一步的听力损失。术前成像必不可少，以避免不必要的镫骨手术。在人工耳蜗植入手术中，脑脊液耳漏和电极误置入内听道可能使手术复杂化。术中应控制脑脊液耳漏，并通过术中成像控制电极位置。
