Expected Reduction of The Nipple-Areolar Complex Over Time After Treatment of Gynecomastia with Ultrasound-Assisted Liposuction Mastectomy Compared to Subcutaneous Mastectomy Alone.

BACKGROUND

The enlarged nipple-areola-complex (NAC) is a characterizing aspect of gynecomastia.

OBJECTIVE

The purpose of this study was to multidimensionally quantify the reduction of the NAC after a subcutaneous mastectomy (SCM) with or without ultrasound-assisted liposuction (UAL).

MATERIALS AND METHODS

A retrospective assessment of patients who underwent SCM +/- UAL due to gynecomastia over a period of 11 years was conducted. The NAC diameters were measured before and after surgery. In addition, a survey (including the BREAST-Q) regarding patient-oriented outcome was performed.

RESULTS

The study cohort consisted of 55 men and resulting 105 NACs (SCM n=63, SCM+UAL n=42). It could be shown that the reduction of the NAC considering all parameters (horizontal and vertical diameter and the area) was significantly larger (p=<0.001) in the SCM+UAL compared to the SCM only cohort. The mean reduction of the area in the SCM cohort was 1.60cm (SD 1.48) or 23.37% (SD 9.78) after 5.82 years and in the SCM+UAL cohort 2.60cm (SD 1.60) or 35.85% (SD 6,86) after 7.43 years. As independent significant factors for reduction of the NAC, the resection weight and SCM+UAL combination were identified. There were no significant differences regarding the patients' satisfaction measured with the BODY-Q (p=0.222) and the ordinal scale (p=0.445) between the two cohorts.

CONCLUSIONS

The SCM with UAL showed a larger reduction over time of the NAC compared to the SCM independent from the stage of gynecomastia. When planning the surgical treatment of gynecomastia, a technique and resection weight dependent reduction of the NAC over time must be considered.
