Tumescent liposuction versus internal ultrasonic-assisted tumescent liposuction.
A side-to-side comparison. Dermatol Surg. 1997 Dec;23(12):1213-8. PMID: 9426671
BACKGROUND: Tumescent liposuction (TL) performed according to accepted
guidelines has proven to be a safe and effective outpatient procedure. The
recent introduction of internal ultrasonic assistance may be a beneficial
adjunct to the proven technique of tumescent liposuction at no additional risk
to the patient. OBJECTIVE: To determine whether there are differences in the
intra- and postoperative course and the final cosmetic result between TL and
internal ultrasonic-assisted tumescent liposuction (I-UATL) with a device using
a double-lumen, saline-cooled cannula. METHODS: Twenty-eight patients were
enrolled in a randomized, prospective, side-to-side comparative study of TL with
and without internal ultrasonic assistance. Intraoperative data including
patient and physician observations are reported. A blinded evaluation was
performed by the nonoperating surgeon of postoperative bruising, swelling,
nodularity, skin retraction, decrease in cellulite, and symmetry at regular
intervals after the procedure. Patients assessed variables concurrently.
RESULTS: In most cases, the surgeon sensed a greater ease of cannula motion on
the I-UATL side, associated with less physician exertion and fatigue. Patients
tended to note a more pleasant intraoperative experience on the I-UATL side. We
found no significant difference in the degree of postoperative bruising,
nodularity, skin retraction, or decreased cellulite as evaluated by the
observing physician, although swelling at 1 week was greater on the I-UATL side.
The degree of bruising, swelling, soreness, numbness, skin retraction, or
decrease in cellulite as reported by the patient did not differ significantly.
There were no major complications attributable to either technique. CONCLUSION:
This study suggests that the addition of internal ultrasonic assistance to the
tumescent liposuction procedure may be advantageous regarding less physician
effort and increased patient comfort during the procedure. We have not shown a
significant difference in the postoperative course or the final cosmetic result
when comparing TL with I-UATL.
