Pleomorphic adenoma of parapharyngeal space derivated from deep lobe of parotid or ectopic salivary gland. Objective: To find out clinical and imagery characteristics in determining the surgical approach for pleomorphic adenoma of parapharyngeal space. Patients and method: 12 patients with pleomorphic adenoma of parapharyngeal space, diagnosed and operated at ENT Hospital from Dec 2008 to Feb 2011. This was prospective and descriptive study.

The dimension the most frequent was from 3 to 6 cm (58.3 percent), 25 percent of tumors was superior to 6 cm. Based on CT and MRI, we stated that 10 tumors derivated from deep lobe of parotid and 2 from ectopic salivary gland. Transcervico-submandibulary approach was performed in 11 cases, the parotidectomy extend approach in 2 cases, no case with endobuccal approach. So far, 1 recurrent after surgery with transcervico-submandibulary approach. Conclusion: CT and MRI had an important role in indentifying the origin of tumors. Surgery with transcervico-submandibulary approach was safe, efficace, least complications.
