“…Upto 80% of parapharyngeal tumors are benign. 3 Pleomorphic adenoma is the most common tumor of prestyloid compartment whereas poststyloid tumors are mostly neurogenic like the schwanoma, paraganglioma, neurofibroma, hemangiomas etc. Chordomas, lipomas, lymphomas, chemodectomas, rhabdomyomas, chondrosarcomas, desmoid tumours, ameloblastomas, amyloid tumours, ectomesenchymomas, fibrosarcomas and plasmacytomas have also been reported.…”

Pleomorphic adenomas are the most common tumors of the parapharyngeal space (PPS) and often grow to an enormous size before becoming visible or symptomatic. CT and MRI scans are important in both diagnosis and surgical treatment. There are basically four different surgical approaches (transoral-transpalatal, transcervical-submandibular, transparotid und transmandibular) to the anterior PPS. Wide and direct exposure of the PPS is provided by a midline mandibulotomy with transection of the floor of the mouth. Owing to its morbidity this approach is reserved exclusively for extended tumors. The transcervical-submandibular route with blunt finger dissection generally offers adequate access for total tumor removal. For adenomas arising from the parotid gland a transparotid approach may be utilized. Adenomas located medially are better be resected transorally by splitting the soft palate.

The parapharyngeal space extends from the nasopharynx to the oropharynx. It is bordered medially by the pharyngeal wall and the constrictor pharyngis muscles, and laterally by the mandible. One distinguishes between a pre- and a poststyloid space. Tumors of the parapharyngeal space are rare and represent less than 1 % of all head and neck neoplasms. Benign (70-80 %) as well as malignant (20-30 %) tumors arise from different structures of the parapharyngeal space, mainly from salivary glands and nerve structures. Concerning salivary gland tumors, most are pleomorphic adenomas typically appearing in the prestyloid space, whereas the schwannomas that may also arise are located in the poststyloid space. The main symptom is dysphagia, with the tumor generally presenting as a visible bulking of the pharyngeal wall, in rare cases also as an externally visible cervical mass. Treatment is generally surgical resection, particularly in benign tumors, preferably via transcervical access. If R0 resection of malignancies is possible, this should be performed. In malignant lymphomas and nonresectable tumors, primary chemo-, radio-, or combination therapy should be considered after histologic confirmation. For neurogenic tumors, particularly vagal nerve schwannoma and especially in older patients, a wait-and-scan strategy is most favorable, since postoperative vagal palsy is unavoidable with surgical resection. Treatment planning for parapharyngeal space tumors requires good knowledge of topographic anatomy and careful evaluation of imaging findings.

Abstract: We demonstrate the differential diagnosis of parapharyngeal tumors as well as their diagnostic and therapeutic management. The tumors should be excised by a transcervical approach to protect cervical vessels and nerves, which is limited by a transoral approach.
