Summary

Background

The aims of the present study were to investigate whether microneurovascular breast reconstruction with a free transverse rectus abdominis musculocutaneous (TRAM) flap and nerve repair with nerves other than ThIV and ThXI improve sensory recovery of the breast compared to traditional free TRAM flap without nerve repair, and which nerve is optimal for the neural anastomosis of the flap.

Methods

<p>Twenty breast cancer patients underwent breast reconstruction with a free TRAM flap and nerve repair (neuro-TRAM) with the best available nerve from the axillary area and 20 control patients had traditional free TRAM flap without nerve repair (standard-TRAM). Neurorrhaphy was done by end-to-end or end-to-side techniques. Sensory and quantitative sensory testings (QST) were performed. Patient satisfaction was evaluated by a clinical questionnaire. The results were analysed by Mann–Whitney tests.

Results

<p>Mean follow-up was 32 months for the neuro-TRAM, and 54 months for the standard-TRAM group. Sensory outcome was better in the neuro-TRAM group (sensory score 45 % of that of the contralateral breast) than in the standard-TRAM group (26 % of the contralateral side). The median (quartiles) of total scores in the operated breasts was 12.9 (9.5–19.2) in neuro-TRAM group and 8.1 (3.5–10.7) in standard-TRAM group (Mann–Whitney Test (p = 0.006)). All nerves available in the thoracic and axillary areas and both of the anastomosis techniques were successful in the reinnervation procedure. Nerve repair did not influence overall patient satisfaction.

Conclusions

<p>This study indicates that any nerve repair results in improved sensory recovery after TRAM flap breast reconstruction. Any nerve available for anastomosis in the recipient site is potentially able to provide moderately good cutaneous sensibility to the TRAM-breast.
