Glossectomy is a disability that leads to dysphagia.To define oral and pharyngeal dysfunctions with regard to the extent of tongue excision and swallowing efficiency.62 patients were videofluoroscopically examined 2 weeks to 3 months after surgery. Oral and pharyngeal disturbances were analyzed according to W.J. Dodd.Impaired tongue movement and absence of oral transport were the most frequent oral dysfunctions. Lack of glossopharyngeal closure and abnormal epiglottis mobility were the most frequent pharyngeal dysfunctions.Oral phase abnormalities are the result of resection of anatomical structures, while pharyngeal abnormalities are due to a delay in pharyngeal phase initiation and defect of synchronization. Videofluoroscopy is a fundamental method to define oral and pharyngeal dysfunction.
