Noncosmetic applications of liposuction.

Noncosmetic applications of liposuction have continued to appear since its introduction into the United States in 1982. Although the most common use is in removing lipomas, liposuction has also been used for benign symmetric lipomatosis, flap undermining, flap defatting, gynecomastia, pseudogynecomastia, breast reduction, buffalo hump, hypertrophic insulin lipodystrophy, lymphedema, evacuating hematomas, emergency neck defatting for airway restoration, and axillary hyperhidrosis. Other uses remain to be discovered.
