Although many aesthetic surgeons believe that beveling the angle of an incision improves the aesthetic outcome with regard to scaring, the literature remains scarce largely because few studies have been conducted.
This systematic review therefore aims to identify whether using a beveled incision adds an aesthetic benefit, to determine whether there is a specific angle that yields a superior outcome, and for the first time, to present a complete discussion of this subject for practicing surgeons.
A comprehensive literature search was performed using the PubMed database to search for primary articles. The main inclusion criteria were primary journal articles investigating the use of a beveled angle via a controlled study.
A total of fifty-four publications were reviewed, with only four publications including 124 patients suitable for use in this systematic review. All the studies concluded that the use of a beveled angle incision improved aesthetic outcomes, with the ideal angle ranging from 10° to 45°.
The use of a beveled angle incision can improve scar aesthetics and encourages the regrowth of hair follicles and shafts through the scars via multiple mechanisms. Nevertheless, the paucity of literature available to the practitioner compels further research assessing this important topic.

尽管许多美容外科医生认为，将切口角度切成斜角可改善疤痕方面的美学效果，但由于相关研究较少，这方面的文献仍然匮乏。
因此，本系统评价旨在确定采用斜角切口是否能带来美学益处，确定是否存在能产生更佳效果的特定角度，并首次为执业外科医生全面讨论这一主题。
使用PubMed数据库进行全面的文献检索，以查找原始文章。主要纳入标准是通过对照研究调查斜角使用情况的原始期刊文章。
共审查了54篇出版物，只有4篇出版物包含124例适合用于本系统评价的患者。所有研究均得出结论，使用斜角切口可改善美学效果，理想角度为10°至45°。
使用斜角切口可改善疤痕美学，并通过多种机制促进毛囊和毛干穿过疤痕再生。然而，可供从业者参考的文献较少，这促使我们进一步研究评估这一重要课题。
证据水平III：本刊要求作者为每篇文章指定证据水平。有关这些循证医学评级的完整描述，请参阅目录或在线作者指南www.springer.com/00266 。
