Trauscervical approach resects primary parapharyngeal space major tumors

Abstract

Objective To evaluate the cervical approach, the diagnosis and therapeutic experi-ence of primary parapharyngeal space (PPS) major tumor for further guidance of clinical work.Methods The clinical data and surgical approach of patients with PPS tumors were restrospectively analyzed.A-mong the patients with PPS tumor more than 10 cm in diameter, 12 were schwannoma,6 were ganglion and 3 were pleomorphic adenoma.2 cases of schwannoma were in both intracalvarium and outside.Trans-cervical approach and transparotid approach were applied.Rusults In 21 cases, 19 cases underwent complete resection and 2 cases underwent partial resection.Jugular foramen syndrome was acquired in 1 case after operation.Hoarse voice happened in 1 case during operation.Homer' s syndrome was found in 2 cases after operation.During a follow-up of 1 to 5 years, no recurrence.Conclusions CT and MRI before operation are valuable to the treatment and selection of surgical approach of PPS tumors.It is no contraindication for transcervical approach that tumor has an intimate relationship for basilar region,vaso-nerves area and a major volume.The transcervical approach is a simple, safe, minimal invasive and effective procedure for basilar region major tumors as long as we modified on operation slightly, and the outcome is satisfactory.
