Videofluoroscopy in motor neurone disease prior to cricopharyngeal myotomy.

Cricopharyngeal myotomy is a recognised treatment for the dysphagia in motor neurone disease, although the results are sometimes disappointing. In this study, 27 patients with motor neurone disease causing significant dysphagia have been investigated by the technique of videofluoroscopy, in order to determine the nature of their swallowing disability; those patients found suitable have been offered cricopharyngeal myotomy. Of the 27 patients, only seven were found to have cricopharyngeal dysfunction as the predominant disability and, of these, six underwent myotomy, resulting in relief of dysphagia in five, three of whom returned to a near normal diet. Previous studies showed poor overall benefit from cricopharyngeal myotomy. Videofluoroscopy allows accurate patient selection, and a much improved outcome in the selected group.
