Immediate versus Delayed Breast Reconstruction Following Mastectomy

Abstract

Introduction: The timing of breast reconstruction after mastectomy affects oncologic safety, aesthetic outcomes, and patient satisfaction. This literature review compares immediate and delayed reconstruction.

Methods: A comprehensive search identified comparative studies and large cohort series. Inclusion: adult women undergoing mastectomy for cancer or prophylaxis with either immediate or delayed autologous or implant-based reconstruction. Outcomes: complications, revision rates, and quality of life.

Results: Fifty-two studies (n=9,873 patients) were included. Immediate reconstruction had higher overall complication rates (25% versus 18% for delayed) but lower total number of operations. Aesthetic outcomes favored immediate reconstruction (patient-reported satisfaction 85% versus 75%). Post-mastectomy radiation therapy negated the aesthetic advantage of immediate reconstruction. Delayed reconstruction allowed more time for patient counseling.

Discussion: Immediate reconstruction reduces psychological morbidity associated with mastectomy alone. However, post-mastectomy radiation significantly impacts implant-based immediate reconstruction. Autologous flaps are more radiation-resistant.

Conclusions: Immediate reconstruction is preferred when radiation is not anticipated. Delayed reconstruction is safer when post-mastectomy radiation is planned. Shared decision-making should incorporate oncologic plans.
