    Abstract:
    Objective:To explore the diagnosis,treatment,surgical approach and prognosis of parapharyngeal space tumors.Method:The clinical data of 188 patients with parapharyngeal space tumor who were treated from January 2007 to December 2016 were analyzed retrospectively.All patients underwent imaging examination before operation.Surgical approach was as follows:transcervical approach applied in 159 cases,endoscopic-assisted transnasal approach in 9 cases,transcervical-transmandibular approach in 8 cases,transcervical-transparotid approach in 8 cases,transoral approach in 7 cases,and infratemporal fossa approach in 4 case.Result:Of the 188 cases,the tumor was benign in nature in 168 cases(89%)and malignant in 20 cases(11%).Complications occurred in 28(15%)patients,with the most common symptom being hoarseness.168 cases of benign tumors were followed up for 10 months to 10 years,and 3 cases were lost and 4 cases had recurrence.All cases underwent re-operation.Patients with malignant tumors received combined treatment after surgery,and 3 cases were lost to follow-up,1 case died of recurrence 9 months after surgery,the rest survived.Conclusion:Surgery is the preferred method for treating parapharyngeal space tumors and postoperative recurrence rate is pretty low.Endoscopy provides a new surgical management method,helping to reduce postoperative complications and recurrence rate.
