title: Cricopharyngeal dysfunction with significant piriform sinus expansion: case report.
abstract: This report describes the case of a patient with cricopharyngeal dysfunction with significant piriform sinus expansion. An 80-year-old man presented with a three-year history of dysphagia. Palsy of the cricopharyngeal chalasis was identified by electromyography under both videofluorography and manofluorography. Although a widening procedure was performed in the cricopharyngeal region using a bougie, the patient gained only minor relief from his dysphagia. After the patient had had adequate time to recover spontaneously (six months), a cricopharyngeal myotomy was performed. As a result, his dysphagia resolved and the post-operative course was uneventful. The clinical and histopathological findings in this case suggested that significant piriform sinus expansion had resulted from the cricopharyngeal dysfunction, due to cricopharyngeal myopathy.
