The infrahyoid myocutaneous flap (IMF) is a local pedicled flap that receives its primary blood supply from the superior thyroid artery and vein. The IMF is formed by the sternohyoid, sternothyroid, and omohyoid muscles. Many reports regarding IMF have been published in the English-language literature, but none from departments of oral and maxillofacial surgery in Japan. The IMF is useful for reconstruction of medium-sized oral soft tissue defects, because it is quick and easy to harvest. We describe a patient in whom the oral floor was reconstructed using an IMF after resection of cancer of the oral floor. A 61-year-old man presented to our hospital with discomfort of the floor of the mouth. After several examinations, he was given a diagnosis of cancer of the oral floor and stomach. Resection of cancer of the oral floor with supraomohyoid neck dissection was performed, and the oral soft tissue defect was reconstructed using an IMF. One month later, laparoscopic distal gastrectomy was performed for the gastric cancer. The postoperative course was uneventful without any recurrence during our 5-year follow-up.
