ObjectiveTo investigate the effect of choosing anterior or posterior pectoralis major plane as the implantation location on postoperative satisfaction of patients undergoing immediate breast reconstruction with prosthesis implantation after breast cancer surgery. MethodsThe clinical data of 46 patients undergoing immediate breast reconstruction with prosthesis implantation after breast cancer surgery were analyzed retrospectively. The implantation planes (anterior or posterior plane of the pectoralis major) were selected based on factors such as the prosthesis volume and patient′s breast shape. Among them, 17 cases′ prosthesis were implanted in the anterior plane of the pectoralis major (included in the anterior plane group), and 29 cases′ prosthesis were implanted in the posterior plane of the pectoralis major (included in the posterior plane group). Patients were followed up 3 months after the operation, and the satisfaction with the breast and prosthesis were compared between the two groups. ResultsFor the effect of breast reconstruction, the satisfaction in the anterior plane group presented as 14 excellent and 3 good, while the satisfaction in the posterior plane group presented as 25 excellent and 4 good, with no statistically significant difference in patients′ satisfaction with the breast between the two groups (P＞0.05). For the prosthesis, both groups were satisfied. ConclusionIn immediate breast reconstruction with prosthesis implantation after breast cancer surgery, preferential selection of the anterior or posterior pectoralis major plane based on factors such as the prosthesis volume and patient′s breast shape can obtain good postoperative satisfaction.
