Tongue flap repair of postlaryngectomy hypopharyngeal stenosis.

Hypopharyngeal stenosis after total laryngectomy has been reported as high as 40%. The most consistent and important causal factor is the extent of the pharyngeal resection since cancers of the pyriform sinus and postcricoid region have the highest incidence of stenosis. Dilation is frequently unsuccessful in the management of postlaryngectomy hypopharyngeal stenosis probably because of its excessive length. The laterally-based tongue flap is effective for repair of these stenoses because of its proximity, epithelial compatibility, and ample length. The technique, details, and successful use in three patients are presented.
