Subpectoral and prepectoral planes have commonly been used in implant-based breast augmentation. The effect of implant plane on complication rate was still unclear. This meta-analysis demonstrated current evidence with regard to comparison of complication rates between subpectoral and prepectoral breast augmentation.
Pubmed, EMBASE and Cochrane library were searched to December 2018. The results of selected studies were meta-analyzed to obtain a pooled odds ratio of the effect of subpectoral versus prepectoral breast augmentation on rates of complications.
There were significantly lower rates of capsular contracture and hematoma but higher rates of implant displacement and animation deformity in the subpectoral group compared with the prepectoral group. There was no significant difference with regard to rates of reoperation, seroma, rippling, infection and implant rupture between these two groups.
Subpectoral and subglandular breast augmentations both have their merits and demerits with regard to complications. The pros and cons of each procedure should be fully explained to patients and selection of implant plane should be considered more comprehensively.

胸大肌下和胸大肌前平面常用于植入式隆乳术。植入平面对并发症发生率的影响尚不清楚。这项荟萃分析展示了目前关于胸大肌下和胸大肌前隆乳术并发症发生率比较的证据。
检索至2018年12月的PubMed、EMBASE和Cochrane图书馆。对所选研究的结果进行荟萃分析，以获得胸大肌下与胸大肌前隆乳术对并发症发生率影响的合并比值比。
与胸大肌前组相比，胸大肌下组的包膜挛缩和血肿发生率显著较低，但植入物移位和动态畸形发生率较高。两组之间在再次手术、血清肿、波纹、感染和植入物破裂发生率方面无显著差异。
胸大肌下和乳腺下隆乳术在并发症方面都有其优缺点。应向患者充分解释每种手术的利弊，并更全面地考虑植入平面的选择。
