Background: This study aims to analyse the quality of studies and revisit the liposuction assisted gynecomastia surgery performed through minimal incision. Methods: A systematic review, based on the literature in the PubMed, Scopus, Science Direct, and Cochrane, to the treatment of Simon’s grade I and II gynecomastia was conducted using keywords “gynecomastia” AND “liposuction.” Study appraisal was performed using MINORS to assess the methodological quality of the paper. Results: There were 18 out of 415 studies eligible to review. A total of 244 out of 1628 patients with the average age of 23.13 years. Liposuction facilitated the easy handling to remove the breast tissue via small incisional design; showed consistent improved quality of life in terms of satisfaction after surgery. However, the measuring method of satisfaction rate varied, resulting in difficulties to interpret the results. Complication rates were inconsistent throughout the studies, ranging from 0.06 to 26.67%. Reoperation rate of liposuction-assisted surgery is between 0.6 and 25%. There are only two studies of a total 25 patients that are considered as good in quality. The two studies, which discuss laser-assisted liposuction technique, show minor complication of seroma in two patients. While one study shows high patient’s satisfaction rate; both studies indicate high surgeon’s satisfaction rate. Conclusion: Small incisional design for breast parenchymal removal in gynecomastia assisted by liposuction showed a good technical approach for consistent improvement in quality of life. However, only 2 studies reported good quality methods of non-randomized case series urging for a better quality of studies in the future.
