Abstract:
Purpose:Patients undergoing breast surgery may experience chronic postoperative pain in the breasts, upper extremities, and axillary regions, and no established methods for preventing this pain are available at present. This study aimed to investigate whether coaptation of the transected intercostal nerve can prevent the development of neuropathic and chronic breast pain after mastectomy in implant-based breast reconstruction.
Methods:A prospective, double-blind, randomized controlled trial was conducted by dividing patients who underwent implant-based breast reconstruction after mastectomy into a control group without nerve coaptation and an experimental group with nerve coaptation.Patient clinical information was collected, and a survey using the pain and quality of life scale was conducted at 6 and 12 months after surgery.
Results:Fifteen patients completed the study, including seven in the control group and eight in the experimental group. The two groups showed no significant differences in terms of clinical factors. The experimental group exhibited lower Short-Form McGill Pain Questionnaire scores than the control group at 6 and 12 months postoperatively, with a statistically significant difference at 6 months. Numerical Rating Scale and Present Pain Intensity scores for both groups were in the “no to mild” range throughout the study period, with no statistically significant differences between the groups. Although the difference in the BREAST-Q™ results did not reach statistical significance, the experimental group showed an improvement in the quality of life.
Conclusion:Intercostal nerve coaptation after mastectomy in implant-based breast reconstruction may facilitate initial nerve recovery. Although trial results are needed to fully determine the clinical impact, our findings support the ongoing scientific and clinical efforts to use this technique.
