Rationale: Lateral chest flaps represent versatile reconstructive options, especially valuable in times of global healthcare resource restriction. In this series, we present our experience with the use of lateral chest wall flaps in both immediate and delayed reconstruction from both breast conserving and mastectomy surgery. Methods: A retrospective cohort study of patients who had undergone a lateral chest wall flap for immediate or delayed breast reconstruction of a lumpectomy or mastectomy defect was performed. Data collected consisted of patient demographics, procedure type, tumor/oncological characteristics, as well as postoperative complications. Findings: Between September 2015 and April 2021, 26 patients underwent breast reconstruction using a lateral chest wall flap. Fifteen patients (58%) underwent immediate reconstruction (9 lumpectomy; 6 mastectomy) and 11 (42%) underwent delayed breast reconstruction. All flaps survived, though 1 patient required partial flap debridement following venous compromise hours after surgery. There were no incidences of hematoma, seroma, infection, or wound healing delay at either the donor site or breast. There was one positive margin which occurred in a mastectomy patient. Significance: This study describes the use of lateral chest wall flaps in a wide variety of reconstructive breast surgery scenarios. This technique can be safely performed in an outpatient setting and does not require microvascular techniques. Review of our outcomes and complications demonstrate that this is a safe and effective option. Our experience is that this is an easy to learn, versatile flap that could be a valuable addition to the surgeon's arsenal in breast reconstruction.
