Evaluation of Breast Skin/Nipple-Areolar Complex Sensation and Quality of Life after Nipple-Sparing Mastectomy Followed by Reconstruction

Background and Objectives: Sensation of the breast skin and nipple-areolar complex (NAC) is commonly assumed to be diminished or completely absent following nipple-sparing mastectomy (NSM) with implant- or expander-based reconstruction. The purpose of this cohort study was to evaluate breast skin and NAC long-term touch pressure sensibility, from 1 month to 1 year, after NSM followed by reconstruction with an implant or expander, and patient quality of life (QoL), hypothesizing that sensibility may diminish with a small progressive return throughout the postoperative period. Materials and Methods: This was achieved by performing sensation tests using Semmes-Weinstein monofilaments (SWM) in nine predefined points of the breast and NAC, a two-point discrimination test (TPD) in the four quadrants of the breast, and QoL assessment using the BREAST-Q. We evaluated 42 patients in Pauls Stradiņš Clinical University Hospital, with a total of 66 breasts, who underwent NSM between 2021 and 2023, performing the breast sensation tests before surgery and postoperatively at 1/3/6 months and 1 year. The BREAST-Q was administered to assess patient satisfaction and well-being. Results: Our results reflect a decline in breast skin and NAC sensation in the 1-month evaluation after NSM (mean: 4.67) when compared to the assessment before surgery (mean: 2.57), with a small progressive return reflected in the 3 months (mean: 3.79), 6 months (mean: 3.68), and 1-year evaluations (mean: 3.14). The following were the mean scores obtained from the BREAST-Q: Psychosocial Well-being (mean: 66), Sexual Well-being (mean: 50), Satisfaction with Breasts Pre-OP (mean: 58), satisfaction with breast reconstruction (mean: 52), Satisfaction with Implants, Satisfaction with nipple reconstruction, Physical Well-being Chest, Adverse effects of radiation, and Satisfaction with Information. Conclusions: This study confirms that sensibility diminishes after this procedure, as observed when comparing the sensation evaluation results before the operation with the 1-month evaluation, reflecting a small progressive return in the following months.
