title: Anterior neopharyngeal pseudodiverticulum. A possible cause of dysphagia in laryngectomized patients.
abstract: Anterior neopharyngeal pseudodiverticula are out-pouchings of the neopharyngeal lumen in laryngectomized patients which can cause postoperative dysphagia. In this study 20 laryngectomized patients were examined endoscopically and with barium swallow to determine the frequency of pseudodiverticulum formation, the correlation with clinical symptoms, and to evaluate the best modality for diagnosis. In 12 patients an anterior neopharyngeal pseudodiverticulum was present. Of these patients eight complained of dysphagia. The barium swallow showed more clearly the pseudodiverticula than laryngoscopy and gave additional information on functional implications. All symptomatic patients were successfully operated on with endoscopic laser therapy.
