title: Pleomorphic adenoma and severe obstructive sleep apnoea.
abstract: Two cases of deep lobe parotid tumours extending into the parapharyngeal space and causing obstructive sleep apnoea are described. Post-operatively, marked improvements in nocturnal hypoxic episodes and the symptoms of obstructive sleep apnoea were seen. Although minor salivary gland pleomorphic adenomas have been described as a cause of airway compromise, pleomorphic adenomata arising from the deep lobe of the parotid, causing proven obstructive sleep apnoea, have not previously been documented. The anatomy and common pathologies of the parapharyngeal space are discussed.
