Parapharyngeal space tumours.

Tumours in the parapharyngeal space have been difficult diagnostic and management problems. Consideration of the anatomy in three dimensions may be illustrated with computed tomography. Fifteen patients with parapharyngeal space tumours are presented, including six salivary gland tumours, four neurogenic tumours and five tumours from miscellaneous origin. The tumours were all treated by surgical excision. The preferred approach was the transcervical route. Additional procedures, including total conservative parotidectomy, were carried out depending on the pathology. Mandibulotomy was required for only one patient whose tumour had infiltrated the base of the skull and extended intracranially.
