Abstract
Objective
To report a multi-institutional clinical experience with the liposhaver in facial plastic surgery.

Design
Nonrandomized, nonblinded, multiinstitutional evaluation of the liposhaver in a clinical setting in patients presenting for cosmetic facial liposuction.

Interventions
Cosmetic facial surgery with the liposhaver was performed in 19 patients (21 procedures) who underwent submental lipectomy, facelift with defatting beneath the facelift flap, and/or correction of deep nasolabial folds. Standardized preoperative and postoperative photographs were obtained. Fat obtained from the abdomen of 1 patient was also studied histologically. This fat was excised sharply and was then liposhaved at varying oscillation speeds.

Outcome Measures
Subjective evaluation by the operating surgeons.

Results
The liposhaver was used successfully in all cases. The fat was cleanly shaved and the contour results were even, without dimpling or asymmetry. Operative time was comparable to that for conventional liposuction. Preferred cannula sizes and settings were determined. There were no cases of facial nerve injury, no evidence of increased bleeding intraoperatively, and no hematomas in the immediate postoperative period. One patient developed a small hematoma on postoperative day 5 that was effectively treated with needle aspiration and a pressure dressing. Histologic evaluation of liposhaved abdominal fat showed normal fat cells and well-preserved architecture.

Conclusions
The liposhaver offers a precise alterative to conventional liposuction. It may be less traumatic because it requires low suction pressures and does not rely on the potentially bruising, vigorous, back-and-forth motion for fat extraction typical of conventional liposuction.
