OBJECTIVE: We have reviewed our experience with cricopharyngeal myotomy for a variety of conditions causing cervical esophageal dysphagia to clarify its indications and results as well as to determine what, if any, ancillary procedures are indicated. METHODS: Eighty-three patients underwent cricopharyngeal myotomy between January 1970 and January 1995, 54 of whom had a pharyngoesophageal diverticulum. The remainder suffered from a variety of motor disorders of the upper esophageal sphincter. Clinical follow-up evaluation was obtained in 71 of the 83 patients (86%). RESULTS: Good or excellent results were obtained in 87% of the patients with pharyngoesophageal diverticula, 100% after myotomy plus diverticulectomy, 87% after myotomy plus diverticulopexy and 67% after myotomy alone. Of patients with hypertensive upper esophageal sphincter, 100% had good or excellent results, whereas only 60% with nonspecific esophageal motor disorders were so evaluated. None of the patients with bulbar palsy or miscellaneous conditions had good or excellent results. CONCLUSIONS: We recommend cricopharyngeal myotomy for all patients with a pharyngoesophageal diverticulum coupled with diverticulopexy for the majority, reserving diverticulectomy for those with recurrent pouches or extremely large pouches (6-8 cm in diameter). Good or excellent results can be expected after myotomy in patients with a hypertensive upper esophageal sphincter. Myotomy is rarely indicated for patients with dysphagia secondary to bulbar palsy. The role of cricopharyngeal myotomy for patients with non-specific esophageal motor disorders remains controversial.
