Abstract

Abstract: Objective To analyze the clinical characteristics and surgical approaches of parapharyngeal space tumors and to explore the advantages, disadvantages, and prognosis of surgical approaches. Methods The data of 67 patients with parapharyngeal space tumor admitted to the First Affiliated Hospital from January 2010 to June 2019 were analyzed retrospectively. All patients were examined using CT and /or MRI before operation. Forty-five cases were operated by lateral transcervical approach, 20 cases by trans-oral approach, and two cases by cervical-transparotid approach. All patients were followed up closely after operation. The follow-up time was from 8 months to 110 months(median: 45 months). Results A total of 59 cases(88.1%)were pathological benign tumors, eight cases(11.9%)were malignant tumors, and 24 cases(35.8%)had postoperative complications. Twenty cases underwent lateral transcervical approach(29.9%), three patients(4.5%)had transoral approach, and one patient(1.5%)had cervical-transparotid approach. Seven patients(10.4%)improved after follow-up, and seven patients(10.4%)had relapse. Four patients(6.0%)underwent lateral transcervical approach, and three patients(4.5%)underwent transoral approach. Conclusion Parapharyngeal space tumors are mainly benign, with a complex anatomy and various pathological types. Surgical resection serves as the main treatment. According to the results of the imaging examination, tumor size and anatomical relationship determine the approach prior to surgery. The lateral transcervical approach is still the preferred method for resection of parapharyngeal space tumors, but in patients with benign tumors with a maximum tumor diameter of <6 cm and located medical to the artery, the transoral approach can be considered.
