Background
Nipple-sparing mastectomy (NSM) and implant-based immediate breast reconstruction are becoming preferred options with improved outcomes. However, reconstruction in patients with large and ptotic breasts is challenging. When mastectomy and skin reduction are combined in a single-staged procedure, the vasculature of the skin is disturbed leading to increased complication rates. This paper aims to compare complication rates of NSM and immediate implant-based reconstruction with or without reduction to determine the safety of reduction in this patient group.
Methods
Breast cancer patients that underwent NSM and implant-based immediate breast reconstruction between November 2010 and 2018 were analyzed. All implants were placed submuscularly. Patients with skin reduction and nipple–areolar complex transposition were matched in a 1:1 fashion with patients without reduction.
Results
There were 50 patients (72 procedures) in each group. Demographics of the groups were similar as a part of matching process. Mean implant volume in the reduction group was higher (399.93 ± 97.54 vs. 360.21 ± 82.54, p = 0.009). Full thickness skin necrosis rate was higher in the reduction group [12/72 (%17) vs. 2/72 (3%), p = 0.009], and the most common site was over the suture line [6/12 (50%)]. Complications in the reduction group were more common in reconstructions with implant volumes greater than 500 cc (p = 0.008).
Conclusions
When compared with no reduction, the skin necrosis rate of NSM and immediate implant-based reconstruction with skin reduction is higher. The described technique can only be considered in patients with moderate breast volumes, grade II–III ptosis, and when the planned implant volume is low (< 500 cc).
