Eleven cases of parapharyngeal mass (2 recurrent pleomorphic adenomas, 2 fresh pleomorphic adenomas, 2 schwannomas, a lipoma, a hemangioma, a foreign body cyst due to bullet, a malignant lymphoma and a carcinoma in pleomorphic adenoma) are reported. If the radiolucent zone between mass and parotid gland is not seen, the mass is likely a tumor of the deep lobe of the parotid gland or large tumor going forward to parotid gland. Therefore, cases without a radiolucent zone should be operated on using a transparotid approach. If the radiolucent zone is seen, the mass is mostly likely extraparotid in origin. In these cases, a transcervical approach is recommended. The intraoral approach should be restricted to cases of extraparotid, small, well capsulated, low vascular and benign tumor. The intraoral approach should be avoided in cases lacking a radiolucent zone, because of the possibility of recurrence and the increased risk of facial nerve injury.
