Suction-assisted lipectomy does not increase the risk of random flap necrosis in a randomized study in pigs.

Thirty-two dorsally based random flaps were raised in eight Yorkshire pigs (26-31 kg) after infiltration with 200 mL of dilute lidocaine (0.1%) with epinephrine (1:1,000,000) into each flap. Prior to elevation 16 of the flaps were treated with syringe-assisted liposuction, while the remaining flaps served as controls. One week postoperatively the viability of the flaps was assessed with computer-assisted planimetry of the necrotic area and by measurement of capillary blood flow using radioactive microspheres. The mean area of necrosis was nearly identical in the flaps treated with liposuction and in the control flaps, and there was no statistically significant difference in blood flow between the groups. The results show that liposuction performed with the "super-wet" or "tumescent" technique can be done prior to elevation of flaps in pigs without increasing the risk of flap necrosis.

Endoscopy for regional lipectomy.

With the advances in endoscopic surgery, reconstructive surgeons search for applications in the field of soft tissue contouring. The improvements in endoscopic surgery in other fields are based on surgery within well-contained spaces that allow insufflation. However, minimally invasive surgery in the soft tissue planes has been limited by the relative inability to control separation of the tissue planes to allow a working space for instrumentation. This animal model shows the ability to open up and elevate any soft tissue space by means of external traction elevation and exact separation of tissue layers to allow endoscopic surgery without the need for insufflation. With the use of endoscopic equipment, the removal of fat from any area of the body becomes a much more precise art because of visualization and illumination and the ability to gain immediate hemostasis while exact contouring through removal of layers of fat can be achieved.

Lipectomy of arms and lipograft of shoulders balance the upper body contour.

Lipodystrophies of upper limbs are less significant than lipodystrophies affecting inferior limbs, and the results of liposuction in that area are not always aesthetically acceptable. The authors topographically studied the amount of fat in a lipodystrophic arm of seven cadavers, and found that the zone located over the humerus' trochiter frequently presents lipodystrophic cumuli. In these cases, the maximum width is not the bideltoid width, but the bitrochiteric width. Intermediate and deep liposuction was performed only over the posterior and external aspect, because superficial and circumferential liposuction may result in multiple irregularities on the anterior and internal surfaces. During the same medical act, fat-graft injection in deltoid region was performed to balance the contour of the scapular belt. With this technique, an aesthetically balanced zone was obtained. The results for 48 patients treated with arm liposuction and fat-graft injection in the deltoid area were very satisfying.

Pectoralis major ruptures postsuction lipectomy for surgical management of gynecomastia.

Over the last decade, suction-assisted lipoplasty has been shown to be a safe and reliable procedure in the hands of trained individuals. A large number of plastic surgeons employ liposuction as an adjunct to surgery for gynecomastia with excellent results and low morbidity. An unusual problem, traumatic rupture of the pectoralis major muscle, has been observed by us in a patient who had undergone the procedure. The physical deficit arising from the injury may go unnoticed in all but the most physically active people, and surgeons should be wary of the possibility of this previously unreported complication.

Temporal changes in fat pad mass and cellularity after lipectomy in Siberian hamsters.

Long-day-housed Siberian hamsters show increases in the mass of nonexcised white adipose tissue (WAT) 12 weeks after bilateral removal (x) of epididymal WAT (EWAT). Although EWAT shows no significant regeneration, surviving EWAT appears to increase in mass to a small degree. The purpose of the present study was to determine the time course for fat pad mass and cellularity changes after EWATx and to test whether surviving EWAT adipocytes undergo hypertrophy or hyperplasia. Male Siberian hamsters underwent EWATx or sham EWATx (SHAM). At Week 0 and at 2-week intervals up to 12 weeks postsurgery, a representative sample of animals from each group were killed. EWAT, retroperitoneal WAT (RWAT), and inguinal WAT (IWAT) were removed, weighed, and processed for cellularity measurement. IWAT and, to a nonsignificant degree, RWAT, increased in mass after EWATx due to fat cell hypertrophy. These changes began as early as Week 4 postlipectomy, but no mass or cellularity change was significant until Week 12. The surviving EWAT adipocytes of EWATx hamsters also were larger than those of SHAM hamsters and, unlike EWAT adipocyte number, increased with time within the EWATx group. SHAM hamsters showed slight increases in the mass of EWAT, but not IWAT or RWAT, due to a nonsignificant doubling of EWAT adipocyte number during the 3 months of the experiment.

Lipectomy, body weight, and body weight set point in rats.

Adult, Wistar male rats were lipectomized or sham lipectomized. The food-hoarding behavior was measured repeatedly and plotted against the animals' body weights. Body weight set point was estimated as the intercept of regression line of hoarding with the X axis. Body fat content was measured with a TOBEC body composition analyzer. Body weight set point, fat content, and girth were obtained initially, after surgery, and after recovery. The hoarding threshold was lowered for 2 weeks after surgery, from 561 +/- 20 to 512 +/- 19 g (lipectomized), and from 582 +/- 15 to 558 +/- 14 g (sham lipectomized). After a 4-week recovery, all rats reached their prelipectomy body weight set point and regained their initial body fat. Five weeks after surgery, no significant difference was found between the body weight set points of lipectomized and sham-lipectomized rats. This indicates that the body weight set point was not mainly modulated by fat depots. The transient lowering of the set point is thought to be due to surgical stress.

Suction mammaplasty: the use of suction lipectomy alone to reduce large breasts.

Procedures that minimize the resultant scars while achieving comparable results are preferred by patients and greatly enhance their overall satisfaction. Suction mammaplasty--and indeed all short-scar procedures that are performed on the breast, face, and body--rely to variable degrees on harnessing the under-appreciated capability of the skin to shrink or retract. Patients with breast hypertrophy represent a wide spectrum of deformities based on NAC size, shape, and location, skin quality and tone, and breast volume. No one breast reduction technique is ideal for reducing all breasts. Suction mammaplasty represents one of a number of methods of reduction mammaplasty that can be selected according to variations in anatomy, patient desires, and surgeon preference.
