Pleomorphic adenoma manifesting as aural polyp. Report of a case.
We report the sixth known case of a pleomorphic adenoma of the external auditory canal. It manifested as an aural polyp, and the diagnosis was made only after microscopic pathologic examination. Complete removal was accomplished after a total parotidectomy (with preservation of the facial nerve) provided access to the parapharyngeal space surrounding the internal carotid artery, where it is postulated that the tumor originated. A thorough knowledge of the developmental anatomy of this area greatly enhances operative success.
