Background: Direct-to-implant (DTI) breast reconstruction after nipple-sparing mastectomy (NSM) with the use of acellular dermal matrix (ADM) provides reliable outcomes; however, the use of ADM is associated with a higher risk of complications. We analyzed our experiences of post-NSM DTI without ADM and identified the predictive factors of adverse surgical outcomes.
Methods: Patients who underwent NSM and immediate DTI or two-stage tissue expander (TE) breast reconstruction from 2009 to 2020 were enrolled. Predictors of adverse endpoints were analyzed.
Results: There were 100 DTI and 29 TE reconstructions. The TE group had a higher rate of postmastectomy radiotherapy (31% vs. 11%; P=0.009), larger specimens (317.37±176.42 g vs. 272.08±126.33 g; P=0.047), larger implants (360.84±85.19 g vs. 298.83±81.13 g; P=0.004) and a higher implant/TE exposure ratio (10.3% vs. 1%; P=0.035). In DTI reconstruction, age over 50 years (odds ratio [OR], 5.43; 95% confidence interval [CI], 1.50?19.74; P=0.010) and a larger mastectomy weight (OR, 1.65; 95% CI, 1.08?2.51; P=0.021) were associated with a higher risk of acute complications. Intraoperative radiotherapy for the nipple-areolar complex increased the risk of acute complications (OR, 4.05; 95% CI, 1.07?15.27; P=0.039) and the likelihood of revision surgery (OR, 5.57; 95% CI, 1.25?24.93; P=0.025).
Conclusions: Immediate DTI breast reconstruction following NSM is feasible in Asian patients with smaller breasts.
