The implementation of TORS for head and neck surgery in Thailand

Transoral robotic surgery (TORS) is a novel surgical treatment of head and neck cancers, mainly for limited tumor in oropharynx and supraglottis. Despite the major advantage of favorable postoperative functional outcomes, many obstacles exist during the implementation of TORS, especially in a country where financial resources are modest. We demonstrated our experience of initiating this sophisticated technology at the largest tertiary hospital in Thailand. A retrospective review study was conducted in patients with benign or malignant lesions during 2014-2020 at Siriraj Hospital. Different periods of operation time between initial and subsequent cases were compared to evaluate learning-curve improvement. A total of 36 patients underwent TORS, with median follow-up time of 18 months. The average time of room set-up, anesthesia, and positioning was 37 ± 14, 13 ± 7, and 15 ± 7 min, respectively. Whilst, the average robotic procedure time and total time in room were 44 ± 19 and 118 ± 31 min, consecutively. There was no significant difference in any time interval, except the set-up time between initial and subsequent cases. The worthwhile utilization of TORS could be administered cost-effectively despite the complicated and daunting implementation of TORS. Whilst, meticulous planning and sufficient training prior to the initiation of TORS can favorably shorten the learning curve of operative staffs in the TORS team.
