The set-back tongue flap method (Schechter 1980) was used to reconstruct defects of the tongue base in two patients with carcinoma of the tongue base; one had primary carcinoma of the tongue base and the other an extension of a lesion originating in the palatal pillar and soft palate. The procedure is described, and the merits and demerits are discussed after a year of observation.The merits of this set-back tongue flap were:1) The operative field for this set-back tongue flap operation was relatively small.2) This flap was secured with a neurovascular pedicle.3) The operation could be completed in a one-stage procedure.4) Muscular atrophy of the flap was apparently so slight that adequate volume of the formed tongue was maintained.5) The whole procedure could be performed relatively easily in a short time.The demerits were:1) The surgical field was limited to the size of the tongue base.2) If tumor had invaded the hypoglossal nerve, this flap could not be used.In conclusion, the set-back tongue flap method was useful for one-stage reconstruction after removal of a "localized" carcinoma of the tongue base.
