Abstract: Purpose: The purpose of this study was to estimate postoperative changes of volume and morphology of pharynx and evaluate the relationship between the changes and swallowing functions by videofluoroscopy in patients with surgically treated oral cancer.Patients and methods: We retrospectively analyzed the medical records of patients diagnosed with oral cancer who treated surgically in Hokkaido University Hospital from January 2002 to March 2010. All patients were performed reconstruction with the free flap. We evaluated the volume and morphology of pharynx using CT scan at preoperatively and 6, 12 and 24 month and more than after surgery. Assessment of the swallowing function was videofluoroscopic evaluation that performed at more than 24 month postoperatively. Additionally, duration of tongue base contact to posterior pharyngeal wall was measured by using videofluoroscopy.Results: Twenty one patients (13males and 8 females) were enrolled in this study. Of 21 patients, 14 were undergone partial or subtotal glossectomy and 7 patients mandibular resection. It was showed that the volume of pharynx after surgery changed and unchanged. Some patients had larger antero-posterior diameters of pharynx than preoperation. Patients whose volume of pharynx increased showed poor swallowing function. They showed aspiration or penetration and reverse of bolus into oral cavity and pharyngeal residue. And their duration of tongue base contact to posterior pharyngeal wall was significantly shorter than others(p<0.01).Conclusion: In patients with oral cancer swallowing function after surgery related with volume of oropharynx especially antero-posterior pharyngeal diameters.
