We reviewed 159 patients undergoing bilateral breast reduction in Chester during a 5-year period. Eighty patients (50.3%) had a BMI of 25 or more in our population. Our overall complication rate was 25.8%. The most frequent complications were delayed healing or dehiscence (10.7%), followed by infection (9.4%) and fat necrosis (3.8%). Postoperative haematoma occurred in two patients (1.3%) and areolar necrosis in one patient (0.6%), all these patients had a BMI of 25 or more. Our results showed the mean BMI was higher in patients with delayed healing, fat necrosis, haematomas, and areolar necrosis. Statistically, however, this difference was not significant.
