BACKGROUND

This study compares the arthroscopic shaver and liposuction with other established methods for treatment of adolescent gynecomastia.

METHODS

Surgical management was via four operative techniques: open excision, open excision/liposuction, arthroscopic shaver/liposuction, or open excision and free nipple graft. Data were collected and compared using independent tests, linear regression models, and one-way analysis of variance.

RESULTS

Patients were stratified by Rohrich grades I -II (low) (N = 47) or III -IV (high) (N = 13). The groups were similar in age ( = 0.662) with lower BMI in the low-grade group (x̄ = 25.36 ± 2.1) vs. high-grade group (x̄ = 27.62 ± 4.0; < 0.001). The low-grade group showed no significant difference in operative time across surgical techniques with decreased mean operative time in the high-grade group using the arthroscopic shaver technique (x̄ = 55.8 ± 7.56) compared with open excision (x̄ = 70.83 ± 11.02, = 0.04), open excision plus liposuction (x̄ = 89.5 ± 24.93, = 24.93), and open excision plus free nipple graft (x̄ = 81.67 ± 19.11, = 0.05). There was no significant difference in complication ( = 0.84) or reoperation ( = 0.68) rates across surgical techniques regardless of grade.

CONCLUSIONS

These findings suggest that the arthroscopic shaver is safe and effective for treatment of both low- and high-grade gynecomastia in adolescents. The results yielded a similar incidence of complications and reoperation across surgical techniques, and the arthroscopic shaver approach demonstrated a shorter operative time compared with other techniques for high-grade gynecomastia.
