New research aims to refine increasingly popular plastic surgery procedures: Buttock augmentation and vaginal rejuvenation surgery

Muscle Atrophy after Buttock Augmentation Using Implants

Fernando Serra, MD, and colleagues of Pedro Ernesto University Hospital, Rio de Janeiro, Brazil, evaluated changes in the gluteus muscle in women undergoing placement of silicone implants to improve the shape of the buttocks. This and other approaches to buttock augmentation surgery have become increasingly popular in recent years.

Comparing preoperative and follow-up CT scans, the researchers found significant muscle atrophy after implant placement. The volume of the gluteus muscle was reduced by about six percent, although there was no associated change in muscle strength. Atrophy may be at least partly related to "intrinsic compression" of the muscle by the implants. There was evidence that the women started to regain muscle volume after three months -- possibly reflecting return to exercise and other activities after recovery from the implant procedure.

Meanwhile, gluteoplasty led to improved body shape, with a curvier, more "gynoid" (female) contour. At follow-up, the women were closer to the "ideal" waist-hip ratio of 0.70.

Thus implant gluteal augmentation meets the goal of providing a more shapely figure, with relatively minor, potentially reversible muscle atrophy, the researchers suggest. "This group plans on continuing their researching into the gluteal augmentation's effects on nerve sensation, quality of life, sexual function, and patient satisfaction," comments Rod J. Rohrich, MD, Editor-in-Chief, in this month's introductory video on the Plastic and Reconstructive Surgery website.

Wide Variation in Labiaplasty Techniques Call for Standard Classification Systems

In the second study, ASPS Member Surgeon Ashit Patel, MB, ChB, of Albany (N.Y.) Medical Center and colleagues analyzed research on the outcomes of vaginal labiaplasty. A review of 19 articles identified nearly 1,950 women undergoing labiaplasty for aesthetic and/or functional reasons.

The analysis showed wide variation in surgical management -- the plastic surgeons in the studies used a total of seven different labiaplasty techniques. However, results were good, with patient satisfaction rates ranging from 94 to 100 percent, and acceptably low complication rates.

Yet it's hard to draw conclusions about patient outcomes because of the wide variation in labiaplasty techniques -- not just in the type of surgery, but also in anesthesia, wound closure, and postoperative care. Dr. Patel and coauthors propose a simple classification technique to aid in comparing the results of future clinical trials. They believe that this could be a useful first step toward matching patients to the surgical technique that's most appropriate for them.

Vaginal labiaplasty, like gluteal augmentation, is a technique that more women are interested in and discussing with plastic surgeons. Dr. Rohrich adds, "As this procedure continues to rise in popularity, plastic surgeons are hard at work to make sure the procedure is safe and effective and that the patient experience is the best it can be."
