Temporomandibular joint dislocation in a post-stroke patient with dysphagia caused by gastroesophageal reflux-related vomiting.

This report describes a rare case of repeated, voluntary, TMJ in a 73-year-old woman with dysphagia and dysarthria. The cause of dislocation was suspected to be voluntary excessive mouth opening associated with gastroesophageal reflux-related vomiting and the desire to eject oral deposits resulting from hypoglossal and facial nerve paralyses. After an oral hygiene intervention, the frequency of TMJ dislocation decreased and finally disappeared. Thorough oral hygiene seemed to contribute to protection against TMJ dislocation.
