title: Radiographic findings after cricopharyngeal myotomy.
abstract: Single film examinations (iodine and/or barium) were reviewed in 28 patients who had undergone surgery on the cricopharyngeal muscle due to Zenker diverticula (24 patients), cricopharyngeal muscle incoordination (3 patients) and pharyngoesophageal web (one patient). All patients had had a myotomy which included the cricopharyngeal muscle and up to 3 cm of the cervical esophagus. Lateral and anterior deviation of the pharynx and cervical esophagus occurred regularly. A pharyngocutaneous fistula developed in 2 patients which healed within 3 weeks. In 5 patients there was a posterior leak of contrast medium during the first postoperative week which healed within 2 weeks. Six of these seven patients with a fistula or a leak had had either a diverticulum removed or sustained an accidental mucosal perforation. No patient had recurrence of diverticula, although, 9 patients developed a cricopharyngeal muscle impression. Iodine and barium examinations are important for monitoring early and late postoperative changes after cricopharyngeus myotomy.
