Giant Pleomorphic Adenoma of Parotid Gland; A Case Report.

We report a case of giant pleomorphic adenoma of parotid gland. The patient was a 66-year-old female who first noticed the mass 30 years previously, although the mass had not been treated. The tumor gradually enlarged and on examination at our hospital on March the third 1999, the tumor was 13×11×9cm. The patient underwent total parotidectomy and since the tumor involved a facial nerve, the nerve was resected and we grafted the cervical sensory plexus. Midline mandibulotomy was performed because the tumor extended to the parapharyngeal space. Histopathologically, there was no evidence of malignancy. Facial palsy was gradually improved postoperatively and there has been no recurrence for two years.
