The parapharyngeal space, deep within the neck at the level between the base of skull and the apex of the greater cornu of the hyoid bone, is an anatomically important region. This space is surrounded by the mandible, parotid gland, pterygoid muscles laterally, and pharyngeal muscles medially. The internal carotid artery, internal jugular vein and 9th, 10th, 11th and 12th cranial nerves pass through this space. It is well known that benign and malignant tumors occasionally rise in this space and that most of them are not detected until they extrude medially or laterally. We experienced in a 30 year-old woman, a large parapharyngeal space pleomorphic adenoma 80g in mass originating from the deep lobe of the parotid gland. The tumor was removed by a cervical-transpharyngeal approach with midline mandibulotomy, in order to avoid the damage of vessels and nerves.
