摘要

The infrahyoid flap is a reliable, thin, and pliable myocutaneous flap, classically used for reconstruction in the oral cavity and oropharynx. It provides a vascularized option that does not require microsurgical expertise, making it an attractive alternative to free flaps in selected patients. We report the case of a 60-year-old woman with squamous cell carcinoma of the tongue, predominantly affecting the left side and crossing the midline. The patient underwent an asymmetrical, midline-crossing partial glossectomy, followed by reconstruction using an infrahyoid musculocutaneous flap. The procedure achieved good oncologic margins and satisfactory aesthetic and functional outcomes without the need for microvascular techniques. This case illustrates the adaptability of the infrahyoid flap in managing complex tongue defects that cross the midline. While traditionally reserved for lateral or hemiglossal defects, our experience supports its extended role in partial glossectomies involving bilateral tongue segments. The infrahyoid flap remains a versatile and reliable option for reconstructing midline-crossing tongue defects in select patients, particularly when free flap reconstruction is not feasible. This report contributes to the growing body of evidence supporting its expanded role in head and neck reconstruction.
