[Rare cases of neurofibroina in the head and neck].

Four cases of neurofibroma rare localized in parapharyngeal space and throat, in external ear and larynx are described. Three of them were isolated tumors and in one case--tumors in external ears developed in course of general Recklinghausen disease. Two cases of neurofibroma in parapharyngeal space had different clinical, CT and microscopic picture. In one case tumor protruded the throat obturating its oral part with osseous elements in its microscopic structure which caused characteristic CT picture. This one was excised through median mandibulotomy with good anatomical and functional result. The second case of parapharyngeal neurofibroma adherent to the superior cervical vertebra and only slightly dislocated the postero-lateral wall of the throat was excised through external cervical approach.
