Cosmetic sequelae after oncoplastic breast surgery: long‐term results of a prospective study

Abstract

To analyze risk factors for the cosmetic sequelae of patients treated with oncoplastic procedures and their impact on patient-reported satisfaction. Prospective nonrandomized study between 2003 and 2020. Complications and cosmetic sequelae were reported by the surgeon. We employed the Clough classification for oncoplastic procedures (Level 1 and Level 2) and to define the cosmetic sequelae (Type I, Type II and Type III). The assessment of satisfaction and quality of life was performed with the BreastQ™ questionnaire. 429 level 1 and 326 level 2 oncoplastic operations were included. We recorded 89 cosmetic sequelae: 55 deformities (type II), 29 asymmetries (type I), and 5 type III defects. The incidence of cosmetic sequelae at 10years for levels 1 and 2 oncoplastic procedures was 11.5% and 20.0%, respectively. The level 2 techniques and the postoperative complications increased the risk of cosmetic sequelae. Patients with cosmetic sequelae did not achieve significant improvements in breast satisfaction. Cosmetic sequelae affect up to 17% of oncoplastic procedures. Most of them appear during the first 5years. Cosmetic sequelae and their predisposing factors should be part of the shared decision-making process with patients, as well as part of the training programs for breast surgeons.
