中文摘要
背景： 报告因中耳或颅底疾病接受外耳道（EAC）盲袋闭合术（BSC）作为部分岩骨切除术（SP）一部分的患者的长期结果，该手术或作为独立手术，或与人工耳蜗植入或侧颅底入路联合进行。
方法： 对2015年1月至2022年12月期间接受SP联合EAC的BSC的患者进行了一项回顾性单中心队列观察性研究。考虑了BSC相关并发症的危险因素，包括术前EAC状况（即畸形、既往外耳道成形术或既往BSC）、手术腔状态（即活动性感染、脑脊液（CSF）漏和硬脑膜开放）以及人工耳蜗（CI）的存在。
结果： 总体分析了158例SP联合EAC的BSC病例，平均随访时间为49.6个月（范围6-102）。其中，67例仅接受SP，55例接受SP并同期CI手术，36例在侧颅底入路背景下接受SP。确定了与BSC相关的危险因素，包括23例既往外耳道成形术、12例既往BSC、2例外耳道畸形、29例活动性感染、37例脑脊液漏或硬脑膜开放以及56例CI。观察到1例BSC裂开需要翻修手术。
结论： 在SP背景下，无论是作为独立手术还是与人工耳蜗植入或侧颅底入路联合，专门与EAC的BSC相关的手术结果分析显示，短期和长期并发症发生率极低。
英文摘要
BACKGROUND: To report long-term results in patients who underwent blind sac closure (BSC) of the external auditory canal (EAC) for middle ear or skull base diseases, as part of subtotal petrosectomy (SP), performed either as a stand-alone procedure or in combination with cochlear implantation or lateral skull base approaches.
METHODS: A retrospective single-center cohort observational study was conducted on patients who underwent SP with BSC of the EAC between January 2015 and December 2022. Risk factors for BSC-related complications were considered, including preoperative EAC conditions (i.e., mal-formations, previous meatoplasty or previous BSC), surgical cavity status (i.e., active infection, cerebrospinal fluid (CSF) leak and dural opening), and presence of cochlear implant (CI).
RESULTS: Overall, 158 cases of SP with BSC of the EAC were analyzed, with a mean follow-up time of 49.6 months (range 6-102). Of these, 67 underwent SP alone, 55 SP with simultaneous CI surgery, and 36 SP in the context of lateral skull base approaches. Risk factors related to BSC were identified, including 23 previous meatoplasties, 12 previous BSC, 2 malformations of the EAC, 29 active infections, 37 cases of CSF or dural opening, and 56 CIs. A single case of BSC dehiscence requiring revision surgery was observed.
CONCLUSIONS: Analysis of surgical outcomes specifically related to BSC of the EAC in the context of SP, either as a stand-alone procedure or combined with cochlear implantation or lateral skull base approaches, showed an extremely low rate of complications in the short and long term.
