Abstract

Abstract: Background: Subcutaneous injection of illicit polymers can result in a number of local complications, including injection-site deformity, granulomas, and skin changes. Objectives: The aim of this study was to compare postoperative complications and symptom flare in patients undergoing surgical excision of foreign-body granulomas. Methods: We retrospectively examined data of patients who underwent surgical removal of foreign-body granulomas caused by polymer injection for cosmetic purposes. The granulomas were removed by ultrasonic-assisted liposuction or en bloc excision with primary closure, skin grafts, or free flaps during 2014 to 2020. Data collected included demographic and operative parameters. Postoperative complications, symptom flare, and time to flare were reported. The relations between type of surgery and complications, symptom flare, and time to flare were determined through statistical analysis. Results: The final cohort included 49 surgeries (42 primary and 7 secondary) in 35 patients. The overall complication rate was 28.9%, with no significant intergroup differences (30.8%, 20%, 66.7%, and 40%; P = 0.328). Wound dehiscence and skin burns were the main complications. An overall symptom flare of 35.1% in surgically treated areas over a mean period of 28.49 months was reported. Chi-squared test indicated statistical significance between type of surgery and symptom flare ( P = 0.004) and between complications and flare ( P = 0.013). Kaplan-Meier test for flare was statistically significant ( P = 0.006) after comparison of the 4 groups. Conclusions: The rate of postoperative complications was similar for each type of surgery. However, en bloc excision and reconstruction by either primary closure or free flap was associated with a significantly decreased rate of symptom flare and a longer symptom-free period.
