[Supraglottic laryngectomy with arytenoidectomy].

Relearning to swallow is frequently difficult after supraglottic laryngectomy requiring arytenoid cartilage resection. We propose a surgical procedure in which a local flap is used to close the pharyngeal defect without approximating the laryngeal remnants and the base of tongue. The procedure opens the median raphe and cuts the hyoid bone along the midline. The strap muscles, the perichondrium from the thyroid cartilage and thyroid lobe on the ispilateral side to the tumor are retracted laterally to be used to close the mucosal defect. Sixty-eight patients with T1-T3 carcinomas of the laryngeal margin with extension to an arytenoid in all cases and limited extension to the medial wall and/or anterior angle pyriform fossa in 33 underwent this surgical procedure. Only 5 patients had local recurrence and 8 a lymph node recurrence. Visceral metastases occurred in 21 patients (33%) and second primary tumors were diagnosed at the time of surgery or during follow-up in 19 patients (28%). Three and 5-year actuarial survival rates were 57 and 51%, respectively. Despite post operative radiotherapy, functional success was obtained in 50 patients (75%). This technique provided good tumor control and a high rate of satisfactory functional results in patients with tumors of lateral margin extended to one arytenoid.
