Corset trunkoplasty is able to preserve postoperative abdominal skin sensation in massive weight loss patients.

Conventional abdominoplasty techniques commonly cause postoperative peri- and infraumbilical skin hypesthesia due to abdominal skin flap undermining. The aim of this study was to evaluate abdominal skin sensation after corset trunkoplasty in massive weight loss patients. Forty-nine massive weight loss patients suffering from excess skin underwent corset trunkoplasty between April 2017 and July 2021. Patient demographics and perioperative complications were recorded. Sensibility of the abdominal skin was measured in three qualities postoperatively using a Semmes-Weinstein monofilament, Tip-Therm^® device for thermal sensation and a cotton wooden stick for sharp/blunt discrimination. Results were compared with a control group of healthy individuals to create a baseline. Revision surgery for major complications was necessary in five cases (10%) including hematoma and major wound healing disturbances. Minor complications that did not require surgical intervention were observed in eight cases (16%). Postoperative abdominal sensibility did not show any significant difference between the patient and the control group in all 16 measured areas. Sharp/blunt and thermal discrimination was positive in all patients for the whole abdominal surface area. The corset trunkoplasty technique is able to address both horizontal and vertical soft tissue excess in massive weight loss patients and at the same time limits loss of sensibility of the abdominal skin. Compared to conventional abdominoplasty techniques the abdominal sensation can mainly be preserved due to absence of undermining abdominal skin flaps.
