RESUMEN
CASE: A 51-year-old woman, who had previously undergone C5-C7 anterior cervical discectomy and fusion, presented with symptomatic hardware failure and subsequently underwent instrumentation removal. Her postoperative course was complicated by an esophageal perforation. Despite initial repair using a rotational flap, the leak persisted, prompting esophageal reconstruction with a radial forearm free flap (RFFF). CONCLUSION: Persistent esophageal perforation is exceedingly rare and difficult to treat. This report discusses the surgical technique for RFFF, an excellent option for revising failed sternocleidomastoid rotational flaps. The decision between rotational repair and free flap reconstruction depends on factors such as defect size, vascularization, wound condition, and donor site morbidity.
