Twenty-one patients with glottal cancer (T1-T3) were operated on by a new method of laryngeal reconstruction following vertical partial laryngectomy.In order to make pseudo vocal cords, we used the pedicled thyrohyoid, sternohyoid, and occasionally sternoclide muscles depending on degree of defect after the removal of tumor. These muscles were cut at the level of the hyoid bone. Then, they become lower-type pedicled muscle flaps.These muscle flaps were connected by suture to make the thyrohyoid muscle replace the outer surface of the muscle bundle. The end of these pedicle muscles joined to the arytenoid cartilage bended through the anterior corner of thyroid cartilage. The fixation of these muscles to the cricothyroid membrane was performed to avoid the displacement of the reconstructed pseudoglottis against the normal vocal level. And these muscle flaps were covered by advancement of hypopharyngeal mucosa.No patients had recurrence locally or generally, and they had no complaints on respiration or deglutition, although their voices were limited to phonate loudly.
