Abstract
BACKGROUND: Complications of radiotherapy after implant-based reconstruction include capsular contracture development, seroma formation, and reoperation for implant removal or replacement. However, there is a lack of studies regarding aesthetic outcomes and complication rates following radiation therapy among patients undergoing latissimus dorsi (LD) flap-based reconstruction with implant insertion for volume shortage. The present study aimed to evaluate clinical and aesthetic outcomes of post-mastectomy radiation therapy (PMRT) among patients receiving both LD flap reconstruction and implant insertion. METHODS: This study comprised 66 patients who underwent mastectomy and breast reconstruction between March 2014 and July 2019. Patient demographics and outcomes were compared among patients who did and did not receive PMRT. Aesthetic outcomes were compared using gross photographs. The incidence of complications, including seroma formation, flap necrosis, nipple-areola complex necrosis, hematoma development, and capsular contractures, was compared between groups. RESULTS: No differences in aesthetic outcomes using gross photos during outpatient follow-up were observed between the radiation and control groups. No significant difference in the frequency of complications was observed between groups. CONCLUSIONS: The use of implants and LD reconstruction are inevitable in a proportion of patients due to a lack of LD flap volume. For these patients, PMRT could be safe treatment option if the necessary precautions are implemented. 2021 Gland Surgery. All rights reserved.
