Massive weight loss patients are often left with significant excess skin, which is associated with reduced quality of life and physical limitations due to the symptoms from the excess skin including pendulation, skin maceration, wounding, pain, and infection. The arm and thigh plasty are procedures that reduce the patient's physical symptoms and increase the quality of life by removing excess skin and shaping the remaining tissue. The aim of this review is to describe patient selection for the arm and thigh plasty, discuss indications, surgical principles, and common complications.
