Abstract：
UNASSIGNED: To assess and compare complication rates of symptomatic external auditory canal (EAC) exostoses treated with drill versus osteotome canalplasty.
UNASSIGNED: PubMed/Medline, OVID, EMBASE, Web of Science, Google Scholar.
UNASSIGNED: A systematic review and meta-analysis in accordance with PRISMA guidelines and standardized bias assessment using the JBI critical appraisal checklist was performed. Studies containing original outcome data on drill and osteotome canalplasty were included. The primary study outcome was complication rates.
UNASSIGNED: Fifteen studies were included, encompassing 1399 total patients (1788 ears) with 530 and 1258 ears in the osteotome and drill groups, respectively. Ten studies used a drill, 2 used an osteotome, and 3 used both. The most frequently reported complications were tympanic membrane (TM) perforation (osteotome group: 5.3% [95% CI: 1.7%-10.9%]; drill group: 3.8% [1.5%-7.1%]), sensorineural hearing loss (SNHL) (0.69% [0.07%-1.9%]; 4.3% [2.2%-7.0%]), and postoperative stenosis (1.1% [0.0005%-4.3%]; 4.1% [1.9%-7.0%]). Use of the osteotome was associated with a lower rate of SNHL (P < .05) and stenosis (P < .05), and a higher rate of TM perforation (P < .05). Heterogeneity of the studies included in the analyzed complications ranged from moderate to high. Level of evidence in the included studies ranged from 2b to 4 and all studies had an overall low risk of bias.
UNASSIGNED: While an osteotome technique may increase the risk of TM perforation, drill canaloplasty may increase the risk of SNHL and postoperative stenosis in EAC exostectomy. The exact quantity of hearing loss could not be definitively evaluated. Additional research with participant randomization is needed to assess clinical efficacy.
UNASSIGNED: Level 8.

摘要：
未经授权：评估和比较钻孔和骨凿管成形术治疗的症状性外耳道(EAC)外生骨的并发症发生率。
未经批准：PubMed/Medline，OVID,EMBASE,WebofScience,谷歌学者。
UNASSIGNED：根据PRISMA指南和使用JBI关键评估清单的标准化偏倚评估进行了系统评价和荟萃分析。包括有关钻孔和骨凿管成形术的原始结果数据的研究。主要研究结果是并发症发生率。
未经评估：纳入了15项研究，包括1399名患者（1788只耳朵），骨凿和钻头组中有530只和1258只耳朵，分别。十项研究使用了演习，2使用骨凿，三个都用了。最常见的并发症是鼓膜（TM）穿孔（骨凿组：5.3％[95％CI：1.7％-10.9％];钻孔组：3.8％[1.5％-7.1％]），感觉神经性听力损失（SNHL）（0.69%[0.07%-1.9%]；4.3%[2.2%-7.0%]），术后狭窄（1.1%[0.0005%-4.3%]；4.1%[1.9%-7.0%]）。使用骨凿与SNHL（P<0.05）和狭窄（P<0.05）的发生率较低相关。TM射孔率较高(P<.05)。所分析的并发症中包括的研究的异质性范围从中度到高度。纳入研究的证据水平为2b至4，所有研究的偏倚风险总体较低。
UNASSIGNED：虽然骨凿技术可能会增加TM穿孔的风险，钻孔成形术可能会增加EAC外切除术中SNHL和术后狭窄的风险。听力损失的确切数量无法明确评估。需要对参与者进行随机化的其他研究来评估临床疗效。
