Labia Majora Augmentation: A Systematic Review of the Literature

Background: Currently, there is no standardized approach for labia majora augmentation and controversies still exist regarding this subject. Objectives: This systematic review aimed to assess the evidence in the literature regarding labia majora augmentation. Methods: On November 20, 2016, we conducted an online search of published articles in the Medline, Embase, and Cochrane databases. All articles describing labia majora augmentation were included in this review. Results: Nine studies were selected for inclusion in the systematic review. Only 2 studies were prospective trials. The most commonly used technique was fat grafting with a total of 4 articles and 183 patients. The mean total injected fat volume ranged from 18 mL to 120 mL per session. Two articles described hyaluronic acid injection techniques. The total injected volume of hyaluronic acid ranged from 2 to 6 mL per session. Three articles used surgical techniques for labia majora augmentation. All included articles did not report any major or life-threatening complications. All techniques demonstrated high satisfaction rates. Conclusions: Labia majora augmentation appears to be a safe, efficient technique with a high satisfaction rate and no reported major complications. However, further randomized controlled trials are warranted.
