title: The infrahyoid flap. A technique for defect closure in the floor of the mouth, the tongue, the buccal mucosa, and the lateral pharyngeal wall.
abstract: The surgical technique, indications, and results of the infrahyoid muscle flap are presented. This flap is fed by the superior thyroid vessels and innervated by the ansa cervicalis. The flap is indicated in case of medium-sized defects in the floor of the mouth, the tongue, the buccal mucosa, and the lateral pharyngeal wall. The advantages of the technique presented include the rapid flap elevation close to the original operating field, the ability to use the motor capability of the flap, and the ability to combine it with other local flaps--for example, the platysma flap. This technique appeared to render excellent function for swallowing and speech. Safe flap grafting is possible only if the internal jugular vein is preserved.
