| Outline of Final Research Achievements |
Treatment strategy for oropharyngeal carcinoma have been confused in this decade. We tried to examine swallowing ability and mechanism of dysphagia after treatment of oropharyngeal carcinoma by 320lines MDCT system. We opted for Gehanno method and the suturing of the posterior pharyngeal wall to the base of the tongue after radical resection of oropharyngeal lateral wall. All patients could eat an oral diet without tube feeding. We caliculated pharyngeal constrictor ratio by video-fluorography, and could find good constriction of oropharyngeal wall after our reconstruction method. We also focused on the crosswise difference and distance between the tongue base and posterior wall of oropharynx. Among the cases of chemoradiotherapy, distance between tongue base and posterior wall tend to be longer, and the area around oropharynx were wider than normal. It may cause lower pharyngeal clearance rate. We are now planning further study for evaluate superiority of our reconstruction method.
