Sliding posterior tongue flap.

A modification of the hemitongue advancement flap is presented which provides greater extensibility to the base of the tongue. This technique allows for reconstruction of T2 tumor defects of the midlateral tongue ranging from 4 to 6 cm in length. Mobility of the tongue is minimally compromised, preserving good speech and deglutition. Excessive bulk is not present to impinge on the mandibular alveololingual sulcus, thus allowing early use of lower dentures without the need for adjustment and relining.
