背景:已经提出了具有不同移植物和植入物的各种技术,以建立具有足够功能的光滑对称的鼻背。广义上,在这方面使用了两类材料:同种异体植入材料和自体移植材料。这些荟萃分析的目的是探讨使用同种异体材料进行背部扩大手术后并发症的发生率。
方法:删除重复后,保留了491篇论文,对标题和摘要进行了资格评估。关于研究类型,包括27项观察性研究,21个回顾性病例和6个前瞻性病例系列。本系统评价和荟萃分析共纳入3803例。
结果:27篇文章报道了合成材料背侧隆鼻的并发症和结果。在随机效应模型中,加权平均百分比为2.75%(95%CI1.61~4.17%).加权平均百分比为1.91%(95%CI0.77至3.54%),0.72%(95%CI0.316至1.31%),和0.78%(95%CI0.43至1.24%)。
结论:广泛使用的异体塑料是膨胀聚四氟乙烯(ePTFE),高密度聚乙烯,和硅胶。并发症的总发生率,感染,偏差,不规则,血肿,挤压,过度修正为2.75%,1.91%,0.72%,0.70%,0.78%,和0.49%,分别。修订率,基于随机效应模型,95CI为6.40%(3.84至9.57)。
背景:这项荟萃分析已在国际前瞻性系统评价注册(PROSPERO,注册号CRD42020209644)。
BACKGROUND: Various techniques with different grafts and implants have been proposed to establish a smooth and symmetric nasal dorsum with adequate function. Broadly, two categories of materials have been used in this regard: alloplastic implant materials and autograft materials. The aim of these meta-analyses is to explore the incidence of complications after dorsum augmentation surgery using alloplastic materials.
METHODS: After duplication removal 491 papers remained that title and abstract were assessed for eligibility. Regarding the study type, 27 observational studies were included, 21 retrospective and 6 prospective case series. A total of 3803 cases were enrolled in this systematic review and meta-analysis.
RESULTS: Twenty-seven articles reported on complications and outcomes of dorsal augmentation rhinoplasty with synthetic materials. In a random-effects model, the weighted mean percentage was 2.75% (95% CI 1.61 to 4.17%). the weighted mean percentage were 1.91% (95% CI 0.77 to 3.54%), 0.72% (95% CI 0.316 to 1.31%), and 0.78% (95% CI 0.43 to 1.24%) respectively.
CONCLUSIONS: The widely used alloplasts were expanded polytetrafluoroethylene (ePTFE), high-density polyethylene, and silicone. The total rates for complications, infection, deviation, irregularity, hematoma, extrusion, and overcorrection were 2.75%, 1.91%, 0.72%, 0.70%, 0.78%, and 0.49%, respectively. The revision rate, based on the random effects model, was 6.40% with 95%CI (3.84 to 9.57).
BACKGROUND: This meta-analysis was registered at the International Prospective Register of Systematic Reviews (PROSPERO, registration number CRD42020209644 ).
