Assessing Perioperative Complications and Cost of Nipple-Areolar Complex Neurotization in Immediate Implant-Based Breast Reconstruction Following Nipple-Sparing Mastectomy: A Matched-Paired Comparison.

BACKGROUND:

Reports suggest neurotization can help restore sensation in patients undergoing implant-based breast reconstruction (IBBR) following nipple-sparing mastectomy (NSM). There is a dearth of information regarding the outcomes and cost associated with neurotization of the nipple-areola complex (NAC). The objective of this study is to determine perioperative complications of performing NAC neurotization in IBBR and analyze the added cost of performing this procedure.

METHODS:

A retrospective chart review was performed of patients who underwent NSM with IBBR. Breasts undergoing neurotization of the NAC were compared to breasts that did not undergo neurotization using 2:1 propensity score matching on age, reconstruction type, and BMI. Primary endpoints included 30-day complications and cost. Statistical analysis included descriptive statistics, t tests, and chi-square tests where applicable with a predetermined level of significance of P < 0.05.

RESULTS:

A total of 15 patients (26 breasts) were in the neurotized cohort and matched to 30 patients (52 breasts) in the nonneurotized cohort. Mean follow-up period was 10 months and significantly lower in neurotized group (P < 0.001). Rates of major and minor complications did not vary by neurotization (P > 0.05). Cases of neurotization added a mean cost of $7839 per breast.

CONCLUSIONS:

As NAC neurotization introduces increased complexity from coordination with the oncologic surgeons, use of microsurgical instruments, and additional implantable devices, it is important to compare perioperative outcomes to standard breast reconstruction. As our institution begins to offer this new technique, we have identified no increased risk of perioperative complications with NAC neurotization.
