Articulation functions of two 2/3 glossectomized patients and a 4/5 glossectomized patients, whose defected tongue were reconstructed by myocutaneous flap, were investigated by intelligibility, dynamic palatography, and compensatory movements of articulators. The results were summarised as follows: 1) Intelligibility was ranged between 41.2-47.1%. In vowel intelligibility, a patients with 4/5 glossectomy was highly deviated in /i/. In consonants, velars were especially confused in patients with 2/3 glossectomy, whereas dental and alveolar sounds were deviated particularly in 4/5 glossectomized patients. 2) According to observation of tongue and flap movements by use of dynamic palatography, the myocutaneous flaps were followed by the movement of residual tongue and participated in articulation. 3) Compensatory postures of lips and mandible were observated in comprehensive glossectomized patients. This tendency was clearly noticed in patients with more inflexible flap and residual tongue. 4) Lowering of intelligibility seemed to be caused partially by the decrease in speed of articulators' movements, the methods of resection and reconstruction, and the duration of the postoperative period.
