Review of the microdebrider excision and liposuction technique (MELT) for the treatment of gynecomastia.

[INTRODUCTION] Numerous advancements have been made in the surgical treatment of gynecomastia. However, one of the greatest challenges faced is the complete excision of the fibrous breast disc. We aim to review and compare the outcomes of the microdebrider excision and liposuction technique (MELT) with other techniques employed at our institution.

[METHODOLOGY] We reviewed patients who underwent treatment for idiopathic gynecomastia at our institution from 2002 to 2017. They were divided into 4 groups: Microdebrider Excision and Liposuction Technique (MELT), liposuction only (LO), open excision only (EO), and liposuction and open excision technique (LET). Complications requiring a revision surgery were recorded (residual breast disc, hematoma formation, and nipple-areolar scars). Phone interviews were conducted to evaluate patient satisfaction.

[RESULTS] A total of 304 patients underwent treatment between 2002 and 2017. Out of which, 51.3% patients were treated by MELT, 17.1% patients by LO, 15.8% patients by EO, and 15.8% patients by LET. The subgroup analysis on patients with clinically palpable breast disc was performed. Patients who underwent LO were 2.58 times more likely to have a revision surgery (p = 0.030) and 4.05 times more likely to have residual breast disc requiring revision surgery (p = 0.006) compared to the MELT group. Patients who underwent LET were 3.26 times more likely to have hematomas compared to the MELT group (p = 0.047). Patients from the EO group were most concerned by scars (p = 0.003).

[CONCLUSION] The MELT is a useful technique for the treatment of gynecomastia especially for patients with palpable breast discs. It can achieve good clinical and satisfaction outcomes as compared to other traditional techniques via a small single incision.
