Various types of surgical methods for the treatment of the axillary osmidrosis have been reported. The purpose of this study was to introduce a new surgical procedure using power-assisted liposuction for axillary osmidrosis and to evaluate its long term outcome. From March 2003 to June 2008, a total of 412 patients underwent surgery for bilateral axillary osmidrosis using superficial power-assisted liposuction. The mean age was 25.4years and follow up period was 24.1months. The results of malodour elimination were graded into 4 categories: poor, fair, good and excellent. Visual Analogue Scale (VAS) was applied to the patients asserting a recurrence (fair and poor grade) at 6 months postoperatively. 377 patients (91.5%) showed good to excellent results. Recurrence of odour occured in 15 patients (3.6 %) and the mean VAS of fair and poor grade were 2.21 and 3.27 respectively. Only 1.8% of patients experienced wound problems (hematoma, infection and skin loss) except for minor complications such as temporary hyperpigmentation and epidermal sloughing. In conclusion, superficial power-assisted liposuction offers advantages such as a low recurrence rate, high satisfaction rate, short operation time, rapid recovery and fewer complications. The author maintains this procedure is a safe and effective method for the treatment of axillary osmidrosis.
