[Single-port transoral robotic surgery for laryngeal and pharyngeal benign lesions].

Objective: To share our experience of single-port transoral Da Vinci robotic surgery for laryngeal and pharyngeal benign tumors. Methods: Three patients aged over 18 years and diagnosed respectively with epiglottic cyst, aryepiglottic fold cyst and thyroglossal duct cyst at tongue base were included who received operations in Hainan Hospital of Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine (Boao Research Hospital of Hainan) between 1 August 2023 and 10 April 2024. There were 1 male and 2 females, with a average age of 59 years old. The clinical diagnosis of these 3 patients was respectively epiglottic cyst, aryepiglottic fold cyst and thyroglossal duct cyst at tongue base. Intraoperative conversion rate, blood loss, operation time, hospital stay, pain score and swallowing function score were analyzed. Results: All three patients successfully underwent the operations with the single-port Da Vinci robotic system. The clean-contaminated resection rate of the tumors was 100%. The conversion rate was 0. The blood loss was 0-7 ml. The operation time was 5-30 minutes. There were no adverse events such as loosening of teeth and soft tissue abrasions of pharyngeal side wall. The rate of oral feeding within 24 hours after surgery was 100%. No postoperative coughing, bleeding, or dyspnea occurred. The average length of hospital stay was 3.7 days. The VAS score decreased 3 days after surgery compared to 1 day after surgery. The swallowing function recovered 1 month after surgery. Conclusion: The single-port transoral robotic surgery for laryngeal and pharyngeal benign lesions is safe and efficient, and has few complications.
