The majority of well differentiated @entity259 are @entity5 of low grade @entity5 . @entity3 by well differentiated @entity259 is an uncommon occurrence. The surgical management of @entity1 with @entity259 invading the upper airway has primarily been by total laryngectomy. Other surgeons recommend in selected cases partial laryngeal and/or tracheal resection. A total of 122 @entity1 with @entity259 were treated in our department between 1967 and 1982. Only seven @entity1 with well differentiated @entity5 had airway invasion. In these seven @entity1 we used a partial laryngeal and/or tracheal resection. In three of the @entity1 with tracheal invasion a myoperichondrial flap was used for closing the @entity8276 . A partial resection of the larynx and @entity825 , and end to end @entity254 between the @entity825 and the remaining part of the larynx was performed in another four @entity1 . The techniques used and a long-term follow-up are presented (Table I).
