OBJECTIVES/HYPOTHESIS: To describe the technique of subtotal petrosectomy (STP), to analyze the outcomes, and to review the literature STUDY DESIGN: A retrospective review.
Four hundred sixty cases of STP performed for various indications were included in the study, which was conducted at a quaternary referral center for otology and skull base surgery. Surgical and audiological parameters, and complications were evaluated. Our results were compared with the existing literature on the subject.
Two hundred ninety-seven (64.6%) patients had been subjected to multiple surgeries before an STP was performed. The most common indication for STP was recurrent chronic otitis with or without cholesteatoma, with 165 (35.9%) patients. Difficult cases of cochlear implantation, temporal bone fractures, and class B3 tympanomastoid paragangliomas were the next most common indications, with 91 (19.8%), 43 (9.4%), and 38 (8.3%) cases, respectively. The median follow-up of the patient pool was 36 ± 19 months. Recidivism and postauricular wound fistula were the most common complications, seen in five (1.1%) patients each. This series of STP is the largest reported in the literature CONCLUSIONS: STP is a very useful and safe surgical tool in the management of a variety of problematic situations in otology, as it offers the possibility of a definitive cure by offering radical clearance. This procedure can be combined safely with hearing implantation procedures.
目的/假设：描述部分岩骨切除术（STP）技术，分析其结果，并回顾相关文献。研究设计：一项回顾性研究。
该研究纳入了因各种适应症而进行的460例STP病例，研究在一家耳科和颅底外科四级转诊中心进行。评估手术和听力学参数以及并发症。将我们的结果与该主题的现有文献进行比较。
297例（64.6%）患者在接受STP手术前曾接受过多次手术。STP最常见的适应症是伴有或不伴有胆脂瘤的复发性慢性中耳炎，有165例（35.9%）患者。耳蜗植入困难病例、颞骨骨折和B3级鼓室乳突副神经节瘤是其次常见的适应症，分别有91例（19.8%）、43例（9.4%）和38例（8.3%）。患者群体的中位随访时间为36±19个月。复发和耳后伤口瘘是最常见的并发症，各有5例（1.1%）患者出现。这一系列的STP是文献中报道的最大规模的。结论：STP是耳科各种疑难病症治疗中一种非常有用且安全的手术工具，因为它通过彻底清除提供了根治的可能性。该手术可安全地与听力植入手术相结合。
