title: Functional outcome after surgery for prevention of pharyngospasms in tracheoesophageal speakers. Part II: Swallow characteristics.
abstract: The swallowing function of 29 patients with primary tracheoesophageal puncture who received either a pharyngeal constrictor myotomy, a unilateral pharyngeal plexus neurectomy, or a unilateral pharyngeal plexus neurectomy with a small drainage myotomy limited to the cricopharyngeus was studied. Swallowing function data were collected on each patient at 3 weeks, 6 months, and 12 months after surgery using videofluoroscopy. Differences in swallowing function among the treatment groups were primarily the amounts and loci of oral and pharyngeal residues. The differing patterns of bolus residue may reflect the different mechanisms that were affected by the various procedures. Despite significant changes in some swallow measures, the patients did not complain of dysphagia. Oropharyngoesophageal swallow efficiency--a clinical measure that weighs the amount of bolus swallowed by total transit time--fell within normal limits for each patient group at each evaluation. This measure may be a better index of the patients' perceived normal swallow than the component variables of residue and transit times would suggest.
