Abstract

We report a case of dysphagia and repeated aspiration pneumonia with expanded piriform sinus. The case is an 88-year-old female, she had suffered from difficulty in swallowing for a several years and finally came to repeat aspiration pneumonia several times a year. In videofluorography and a contrasted study, we observed the left piriform sinus expanded in comparison with the other side. And contrasted trachea suggested that aspiration should exist. Judging from these studies, we decided to perform an operation. We removed the surplus mucous membrane of the piriform sinus and performed cricopharyngeal myotomy. The excision was grossly normal, but thyropharyngeal muscle was abnormally thin. According to these surgical findings, we supposed that etiology was a chronic rise of the pressure in the pharynx because of some functional obstacle in passage. In videofluorography as a postoperative examination, the image of piriform sinuses were symmetrical, and swallowing looked almost normal. After the operation, dysphagia disappeared and aspiration pneumonia has since never been observed.
