Researchers have found that long-term breast reduction outcomes can be improved by using techniques that minimally disrupt the lower breast suspensory ligaments. < br>
"Breast reduction is one of the most commonly performed plastic surgery procedures. The long-term appearance after reduction is not optimized 50 percent of the time using standard reduction techniques," noted lead author Frank Lau. "At LSU Health New Orleans, we offer an improved technique that preserves more of the critical breast anatomy. This study provides an anatomical foundation for why our technique may yield better, longer-lasting results."
About 50 percent of patients who undergo the most commonly used breast reduction technique experience pseudoptosis or "bottoming out" as a long-term complication. This occurs when breast tissue drops to the lower portion of the breast independent of nipple position. "We want our patients to have a long-lasting, aesthetically pleasing breast shape," said Lau. Believing that disruption of the lower suspensory ligaments may be a critical factor because they are stronger than the upper sensory ligaments, the researchers conducted a retrospective review of 208 patients who underwent breast reduction surgery from 2008-2015, studying the results in 400 individual breasts.
An anatomic basis for this differential may exist. A horizontal membrane of dense connective tissue originating at the level of the fifth rib that divides the breast into segments at the level of the nipple has been described. This division may signify a transition point in sensory ligament strength. On that basis, the authors recommend that techniques such as the Boston modification of Robertson technique should be preferred by surgeons seeking to avoid pseudoptosis. Other advantages of the Boston modification of Robertson technique include decreased operative time and elimination of the "triple point," the most common site of postoperative incision rupture. "This study is one of the largest breast anthropometry (measurement) studies ever performed," concluded Lau. "These results help us provide the best breast reduction outcomes to our patients."
