Gynecomastia is an abnormal increase in the volume of the male breast. There are three main types of gynecomastia: glandular, fatty-glandular, and fatty. The fatty type can be treated by liposuction alone. However, patients affected by gynecomastia with significant glandular enlargement do not respond to suction alone and may require sharp dissection or skin reduction that leaves scars and deformities disturbing to the patients. The UAL was used for the correction of gynecomastia, and the cavitated and emulsified breast tissues were removed by Rosenberg cannula through 1-cm incision at the inframammary crease. 
Series of 27 cases(54 breasts) were reviewed from 1999 - 2000 with mean follow-up of 6 months. The volume of aspirates ranged from 120 to 330 cc per breast. There were no major complications such as skin flap necrosis or hematoma. Two reoperations were performed for the underresected cases and both responded to liposuction well. The patient safisfaction was high and most of them were pleased with the scars and shapes of the breasts. 
This procedure can minimize scars and reduce the incidence of contour problem such as saucer deformity, and avoid the sensory disturbances. Patients can return to full activities in 48 hours.
