Abstract:
Objective:To investigate the efficacy and feasibility of transoral robotic surgery (TORS) for resection of tumors in the parapharyngeal spaces.Methods:The clinical data of 57 patients who underwent TORS for parapharyngeal space tumors from September 2018 to February 2024 were retrospectively analyzed. These patients were treated at five medical institutions: The First Affiliated Hospital of China Medical University, Eye & ENT Hospital of Fudan University, Sun Yat-sen Memorial Hospital, Sun Yat-sen University, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, and Sun Yat-sen University Cancer Center. The patients were 28 males and 29 females, aged 17-77 years (median age, 47 years). The pathological types, locations, and sizes of the tumors, operation time, intraoperative bleeding volumes, postoperative hospital stays, and postoperative complications were evaluated. The data were analyzed using SPSS 27.0 software.Results:Postoperative pathological examination revealed 11 types of benign tumors. Among 57 cases, 27 cases had their tumors in the prestyloid spaces, predominantly with pleomorphic adenoma ( n=17), and 30 cases in the retrostyloid spaces, predominantly with schwannoma ( n=22). The tumor volumes ranged from 0.6 to 130.1 cm3, the intraoperative bleeding volumes ranged from 5 to 1 000 ml, the operation time ranged from 20 to 390 min, and the postoperative hospital stays ranged from 2 to 25 days. The total costs for individual cases were 36 000-100 000 yuan, with the highest cost in the case suffering from cerebrovascular accident. Four patients(7.0%) had tracheotomy and 36(63.2%) had nasogastric tube placement. Among the 57 patients, 5 had postoperative cavity effusion, 2 had wound dehiscence, 2 had cerebrovascular accidents, 1 had Horner syndrome, and 2 had other complications. The patients were followed up for 1-67 months, with only 1 patient with intracranial and extracranial communication relapsed. Conclusion:TORS is a safe and feasible approach for treating parapharyngeal space tumors, offering advantages such as minimal invasiveness, reduced blood loss, and faster recovery. It is suitable for parapharyngeal space tumors of various pathological types and locations. The postoperative complications are manageable, with favorable long-term follow-up results and low recurrence rates.
