The Comparison Between DEDTI BR and T/E BR

This is a national multicenter, prospective, cohort study. The study aims to compare surgical safety (e.g., surgical complication rates), surgery-related indicators (e.g., operation time, number of operations, surgery-related costs, contralateral breast adjustment operation rates), aesthetic outcomes (e.g., BREAST-Q scores, Harris scores, SCAR-Q scores, Ueda scores and QLQ-BR45 scores), and divorce rate between patients undergoing delayed endoscopic direct-to-implant breast reconstruction via an axillary approach and those undergoing the two-stage expander-to-implant breast reconstruction following simple mastectomy.
