Parapharyngeal tumours are rare. Usually they are asymptomatic but by growing they can reach compressive clinic and displacement of adjacent structures, as the case presented, with 8 cm of diameter. They are usually benign. To complete diagnosis on require a full radiological study with CT and MRI, and a cervical ultrasoundguided FNA. Initially an open biopsy is not recommended, but sometimes can be useful to achieve a diagnosis. Complete surgical excision is the treatment of choice. The approach will be chosen according to the origin, extension and pathologic characteristics. The most common are the transcervical, cervical-transparotid and transmandibular approach. As most of these tumours are benign, the best approach to be used, should be the one that involves less morbidity and less risk of recurrence for the patient. Post-operatives complications depend on the surgical approach used. Lower cranial neuropathies are the most frequent, but mostly are transient and resolve spontaneously.
