Safety and efficacy of single-center transoral robotic surgery for pharyngeal and laryngeal lesions

Abstract

Objective To explore the safety and effectiveness of transoral robotic surgery(TORS) in the treatment of pharyngeal and laryngeal lesions. Methods From 2016 to 2018, the clinical data of 9 cases underwent TORS in Nanjing Drum Tower Hospital were retrospectively analyzed, including 6 cases of oropharyngeal tumors and 3 cases of parapharyngeal space tumors. The operation time, intraoperative blood loss, postoperative fasting time, postoperative hospital stay, postoperative pain and dysphagia scores, postoperative bleeding and nerve injury and other complications were analyzed. Results All 9 patients completed the lesion resection through TORS. The postoperative pathology was benign in 3 cases and malignant in 6 cases, and all resection margins were negative. The operation time was 55-140（85.56±28.77）min. The intraoperative blood loss was 10-50（23.33±11.73）mL, no gastric tube was placed after the operation, the time to resume eating and drinking was 1-3（1.78±0.67）d, and the postoperative hospital stay was 4-7（6.00±1.00）d. Except for 1 oropharyngeal tumor patient who had bleeding from the wound on the day after operation, no complications occurred in the rest. The postoperative follow-up was 4-86 months, and there was no local recurrence, distant metastasis or death in the tumor patients. Conclusion Based on the existing case experience, it can be confirmed to a certain extent that the TORS to resection of throat lesions is safe after reasonable selection of indications and surgical methods, and perioperative and postoperative long-term follow-up effective and minimally invasive.
