title: A review of tumours of the deep lobe of the parotid salivary gland.
abstract: Tumours of the deep lobe of the parotid gland may present as a swelling in the oropharynx. They are uncommon when compared with those of the superficial lobe, are frequently misdiagnosed and subjected to per-oral biopsy which is hazardous and predisposes to seeding of the tumour. Investigation and diagnosis are discussed with particular reference to the role of computed tomography. The surgical approach to these inaccessible tumours is illustrated by reference to patients treated. Modifications to the technique of Cooke and Ranger (1969) for excision of parapharyngeal tumours are suggested, which are applicable to tumours of the deep lobe extending medial to the mandible and presenting in the side wall of the pharynx.
