Abstract
Thirty-eight patients with swallowing disorders underwent cricopharyngeal myotomy. The causes of the disorders were muscular in 12 cases, neurologic in 12, cricopharyngeal achalasia in 7, and unknown in 7. Surgery succeeded in 21 patients, gave a partial improvement in 4, and failed in 13. The quality of residual pharyngeal propulsion on clinical, manometric, and radiologic assessment appeared to be a more important predictor of surgical outcome than upper esophageal sphincter relaxation and the major factor in establishing the indications for cricopharyngeal myotomy. Achalasias in the elderly and oculopharyngeal muscular dystrophies had the most favorable outcome.
