ABSTRACT
We conducted a retrospective study of six patients presenting a parapharyngeal tumor and an analysis of data of the literature and recall classification of these tumors and their anatomo-clinics characters, therapeutic and diagnostic problems highlighting. These tumors are rare and have various origins, their treatment is almost always surgical by cervical approach which can be undertaken only after a rigorous exploration, systematically associating computed tomography scan and magnetic resonance imaging. Transoral resection is strongly advised against as it is potentially harmful.

The potential risk of prion contamination has led the government authorities to stop the use of dura mater allografts of human origin. The aim of this work was to determine the potential risk for implantation of allografts in otology and to review the current reglementation. Although Creutzfeldt-Jakob's disease has not been reported to be transmitted by these allografts and despite the apparently rigorous decontamination methods used by the manufacturers which meet the most severe international recommendations, it is apparently necessary to stop implantation for the time being. This decision has resulted from the lack of a precise directive from the governmental authorities and the uncertainty about prion transmission and the reel effect of inactivation procedures.
