The aim of the study was to report our experience with the use of radiology in functional disorders of the cricopharyngeal muscle and their surgical therapy using digital cineradiology. Five-hundred and seventy dysphagic patients underwent dynamic study of the oral and pharyngeal phases of swallowing (Videofluoroscopic Swallowing Study, VFSS). A motor disorder of the cricopharyngeal muscle was diagnosed by videofluorography in 19 patients: the disorder was mild in 8, moderate in 7 and severe in 4. Two of these underwent cricopharyngeal myotomy, with an improvement in their dysphagia and swallowing mechanisms. VFSS provides a morphological and functional view of the aero-digestive tracts: this is essential in the diagnosis of cricopharyngeal dysfunction and is capable of revealing the related laryngeal penetration and tracheal aspiration. VFSS must always include an oesophageal phase study because of the known clinical and physico-pathological correlations between the gastro-oesophageal junction and the upper oesophageal sphincter. On the basis of our experience we believe that VFSS could be used as a primary investigation, followed by motility studies, and that it may be a useful complementary procedure both in the diagnosis of pharyngo-oesophageal junction motor disorders and with a view to surgical indications.
