Background: While negative impacts of radiation on breast reconstruction have been well accepted, timing of autologous breast reconstruction in the setting of postmastectomy radiation therapy (PMRT) is still evolving. This study aims to address the dilemma of breast reconstruction timing in patients receiving PMRT. Methods: A retrospective chart review was performed evaluating patients who underwent PMRT and autologous breast reconstruction. Postoperative complication and revision rates were compared. Results: Thirty-six immediate (immediate breast reconstruction IBR) and 89 delayed reconstructions (delayed breast reconstruction DBR) were included with comparable patient characteristics between groups. Overall complication rates were not significantly different, or when separately assessing for surgical site infections, wound dehiscence, fat necrosis, or substantial volume loss. No free flaps were lost in either group. Revision rates were significantly lower in the IBR group (p = 0.02). DBR resulted in appreciably larger volumes of fat grafting to the therapeutically reconstructed breast (p = 0.01) and more contralateral mastopexies (p = 0.02). No significant difference was observed in fat necrosis excision, breast reduction, or need for secondary flap reconstruction or prosthetic use for volume loss. Conclusions: IBR in the setting of PMRT does not result in higher rates of complications and requires fewer overall revisions, making it a compelling option for patients undergoing PMRT.
