Abstract
Balloon dilatation has become a widely accepted technique in the management of oesophageal and other gastrointestinal strictures. The use of this procedure in the pharynx has rarely been reported. We have performed 55 balloon dilatations on 13 patients with pharyngeal strictures. In three patients all symptoms were permanently abolished after one dilatation. Seven patients were successfully managed with repeated, regular dilatations. Two patients had a good initial response but this was not maintained and one patient had no relief of symptoms. Balloon dilatation is minimally invasive, less traumatic than rigid pharyngoscopy with dilatation, and well tolerated. It may be frequently repeated, and has successfully relieved dysphagia caused by benign and malignant strictures of the pharynx, including instances where previous rigid bouginage had failed.
