Neurotization Does not Prolong Operative Time in Free Flap Breast Reconstruction.

[BACKGROUND] Neurotization during the breast reconstruction process can improve patient quality-of-life and satisfaction with reconstructive outcomes. One concern with neurotization is increased total operative time due to the need for additional dissection and nerve coaptation. The purpose of this study was to compare total operative time between neurotized and non-neurotized abdominal-based, free flap breast reconstruction.

[METHODS] A retrospective review was conducted of consecutive patients who underwent unilateral, abdominal-based, free flap breast reconstruction between 2016 and 2018 at a single tertiary care center. Data were collected on patient demographics, surgical techniques, and length of surgery. Data analysis was performed using chi-square test, independent t-test, and multivariate linear regression analysis. A p-value ≤0.05 was considered statistically significant.

[RESULTS] Seventy-three patients were included in this study. Twenty-three patients (31.50%) underwent flap neurotization (N group) and 50 (68.49%) underwent standard breast reconstruction without neurotization (NO group). The groups were similar in age, BMI, smoking status, and ASA class. No difference was found between the two groups in timing of reconstruction (p = 0.388). Average operative times were 467.73 ± 145.52 minutes and 455.28 ± 111.19 minutes for the N and NO groups, respectively, with no significant difference between the two groups (two-tailed p-value = 0.72).

[CONCLUSION] Seamless integration of neurotization in abdominal-based, free flap breast reconstruction is possible without significant prolongation of total operative time.
