[Parapharyngeal nerve tumors (10 recent cases)].

The authors describe ten cases of these rare tumours. They run through rapidly the histological and anatomical classifications. The cases consist of 8 schwannomas (one retropharyngeal schwannoma, two which had developed in the anterior sub-parotid space one of them a malignant schwannoma, the other two were two schwannomas of the sympathetic and three schwannomas of the X). A ganglioneuroma of the sympathetic and a paraganglioma of the X are also described. The authors draw attention to the clinical and anatomopathological distinction between the anterior and posterior sub-parotid spaces; to the need to treat tumours which develop there by surgery; to the different surgical techniques and methods of approach.
