Abstract
Six in-patients with dysphagia of neurogenic origin were studied. All patients underwent cricopharyn. geal myotomy. Manometry using four micro-tip transducers was performed bofore and after surgery. Comuputed analysis of swallowing pressure displayed propagation of pharyngeal peristaltic waves to PE junction and cervical esophagus. All pharyngeal peristaltic waves were propagated to PE junction. Disappearance of peristaltic waves were observed in cervical esophagus of three patients. Manner of propagation of peristaltic waves were indifferent to severity of dysphagia and the results of cricopharyngeal myotomy.
