Systematic review of the literature.
The goal of this study is to review and summarize current literature on local flap reconstruction of external auditory canal (EAC) defects.
PubMed and Ovid databases were queried utilizing search term combinations of "external auditory canal," "defects," "flaps," "local," and "reconstruction." References in included articles were subject for review and inclusion. Articles published between 2013 and 2023 were included in the study.
A total of 108 articles were screened after duplicates were excluded. Of the 108 articles, 3 were not written or translated to English, 10 were not accessible for review on either database, and 71 were not applicable to our subject of interest. The remaining 24 articles were included in the systematic review. Due to the primary descriptive nature of the surgical techniques and variability of data collection, a formal meta-analysis was not possible.
The EAC defect creates a difficult reconstructive dilemma. The armamentarium for repairing these defects can range from healing by secondary intention to free tissue transfer, however, local flap reconstruction proves to be a reliable and versatile option. This article reviews current local flap techniques for EAC defects and compares their advantages and disadvantages. Further, the authors provide a treatment algorithm and indications for choosing each flap in external auditory canal reconstruction.
文献系统综述。
本研究的目的是回顾和总结当前关于外耳道（EAC）缺损局部皮瓣重建的文献。
利用“外耳道”“缺损”“皮瓣”“局部”和“重建”等搜索词组合查询PubMed和Ovid数据库。纳入文章中的参考文献也需进行审查并纳入。2013年至2023年发表的文章纳入本研究。
排除重复文章后，共筛选出108篇文章。在这108篇文章中，3篇未写成英文或未翻译成英文，10篇在两个数据库中均无法获取以供审查，71篇与我们感兴趣的主题无关。其余24篇文章纳入系统综述。由于手术技术主要为描述性且数据收集存在差异，无法进行正式的荟萃分析。
外耳道缺损造成了困难的重建难题。修复这些缺损的手段范围从二期愈合到游离组织移植，然而，局部皮瓣重建被证明是一种可靠且通用的选择。本文回顾了当前用于外耳道缺损的局部皮瓣技术，并比较了它们的优缺点。此外，作者提供了一种治疗算法以及在外耳道重建中选择每种皮瓣的指征。
