title: Sleep apnoea of unusual origin.
abstract: A 72-year-old man presented with a history of progressive sleep apnoea. The cause was a large superior laryngeal nerve schwannoma arising in the left parapharyngeal space. This had a ball-valve effect on the laryngeal inlet. Superior laryngeal nerve schwannomas are very rare. No documented case has presented with obstructive sleep apnoea before.
