[A primary pleomorphic adenoma of the parapharyngeal space].

The rarity of benign primary neoformations in the parapharyngeal space associated with aspecific clinical symptomatology often leads to the identification of large size lesions with deformation of the lateral wall of the pharynx and homolateral hemiplate. The improved diagnostic specificity of radiological instruments like CT and NMR allows a precise topographical localisation of the mass and the diagnosis of its nature in 90% of cases. The deep position of the neoplasia makes it necessary to search for the most conservative surgical approach possible that enables a sufficiently broad operating field to be obtained for complete exeresis and the control of neck vessels. This paper describes the therapeutic protocol used and makes a critical revision of the surgical approaches in an exemplary case of primary pleomorphic adenoma in this region.
