[Videofluoroscopy of the pharyngoesophageal segment after total phonatory laryngectomy].
Twenty-nine postoperative videofluoroscopic studies of the pharyngoesophageal segments, with phonation test, were compared with esophageal manometry findings. The group was drawn from an overall group of 220 patients who underwent total phonatory laryngectomy (1984-94) by tracheoesophageal puncture (TEP) and prosthesis insertion. Radiological videofluoroscopic features were defined (type I and type II) and found to correlate with patterns of esophageal manometry in 20 explorations. After surgery, these patients (type I VF) remained hypotonic, had fewer swallowing disorders and prosthesis fracture, and achieved a longer phonation time.
