Indication and surgical technique for extended hemilaryngectomy

Previous experience has shown that conservation of the healthy hemilarynx is possible for the treatment of extended lateralized laryngeal and hypopharyngeal cancers. One major indication for supracricoid hemilaryngectomy is glottic cancer involving either the arytenoid or Morgagni's ventricle. Hemilaryngopharyngectomy is also indicated when tumor of the pyriform sinus involves its anterior part, lateral wall, medial wall and ary- and pharyngoepiglottic folds. Supracricoid hemilaryngopharyngectomy was performed in seven cases. The resection consisted of removal of the surpacricoid hemilarynx and ipsilateral pyriform sinus. The reconstruction was performed by elevating the posterior pharyngeal wall and suturing the mucosa to the midline. This surgical technique provided good functional results. Patients had no airway impairments, but the recovery of satisfactory deglutition may require 14-32 days. Phonatory rehabilitation was successful, and each patient had a satisfactory vocal quality. Postoperative irradiation did not affect the functional results.
