ABSTRACT
BACKGROUND:
Sensation after autologous breast reconstruction is an increasingly important outcome. Several studies demonstrated improved sensation with flap neurotization but utilized heterogenous measures and follow-up intervals. This review evaluates sensory outcomes after neurotization using uniform, objective outcome measurements.METHODS:
PubMed/Medline and Embase databases were queried for articles published between January 1990 and January 2022. Inclusion criteria included studies with free flap tissue transfer breast reconstruction patients and use of Semmes-Weinstein Monofilaments (SWM) to quantify return of sensation after either neurotization or no neurotization. Reviews, case reports, and studies utilizing implants or pedicled flaps were excluded.RESULTS:
Overall, 513 articles were screened. Eleven articles met inclusion criteria for a total of 474 patients. There were 254 non-neurotized patients included as controls (Group A) and 220 neurotized patients (Group B). Mean follow-up time was similar in both groups (22.06 months vs. 22.78 months, p > 0.05). There was no significant difference in age (Group A = 49.97 years vs. Group B = 42.47 years) or BMI (Group A = 25.48 vs. Group B = 25.97) between groups. More patients in group B received radiation therapy (Group B = 32.72% vs. Group A = 20.86%, p > 0.05). Patients that received neurotization had lower mean pressure thresholds (Group A = 38.85 gm/mm2 vs. Group B = 6.69 gm/mm2 , p = 0.053) than comorbidity-matched controls.CONCLUSION:
Neurotization has been shown to be a safe and feasible option for enhancing return of sensation after breast reconstruction. Future studies with standardized, long-term follow-up will further elucidate the pattern of breast sensation return and the impact of neurotization.
