Swallowing function was investigated in 5 oral cancer patients who underwent secondary unilateral radical neck dissection. The test food consisted of 10 ml liquid. Evaluation of the swallowing function was examined at preoperatively and 1 month and 6 months postoperatively. The evaluation was examined about the position of the hyoid at rest, the most elevated position of the hyoid, pharynx passage time and the degree of maximal opening of the esophageal entrance during swallowing with the picture analysis equipment.<BR>1. There was no postoperative change in the position of the hyoid at rest.<BR>2. There was no postoperative change in the most elevated position of the hyoid during swallowing.<BR>3. There was no postoperative delay in pharynx passage during swallowing.<BR>4. There was no postoperative reduction in the degree of maximal opening of the esophageal entrance during swallowing.<BR>Our findings suggested that after unilateral resection of the anterior and posterior bellies of the digastricus and omohyoideus muscles, there was no deterioration of the movement of the hyoid and the opening of the esophageal entrance during swallowing.
