This report describes 25 patients with reflux-induced cricopharyngeal
dysphagia ultimately requiring surgical management. Eighteen patients
underwent cricopharyngeal myotomy alone and seven patients required
cricopharyngeal myotomy after an antireflux operation failed to correct
this symptom. Cricopharyngeal incoordination was demonstrated at manometry
in over 90% of patients. Treatment included cricopharyngeal myotomy, which
was extended proximally to the pharynx and distally to the intrathoracic
esophagus. Results were excellent to satisfactory in 24 of 25 patients.
Pathologic examination of the cricopharyngeal muscle demonstrated a wide
variety of myopathic degenerative changes. We stress that cricopharyngeal
myotomy may be performed even in the presence of reflux without fear of
subsequent aspiration.
