Objective:
To assess the opinion, practices, and challenges of international key opinion leaders about two minimal invasive surgical techniques in supraglottic laryngeal tumours: transoral laser microsurgery (TLM) and the transoral robotic surgery (TORS).
Methods:
Design of a questionnaire composed of seven sections and fifty questions covering descriptive data of participants, practitioners experience procedural sequences, considerations related to airways, feeding, and voice, intraoperative haemorrhage, postoperative management, and a comparative analysis of TLM and TORS in treating supraglottic laryngeal cancer.
Results:
A total of 27 head and neck surgeons replied to the survey. The experts had an average experience in laryngeal surgery of 20.0 ± 9.4 years, ranging from 5 to 36 years. We noted a significantly shorter installation time in TLM compared to TORS (19% of experts estimated the installation time of over 20 min with TLM vs 44% with TORS; p = 0.02). According to complications, the experts considered that bleeding was the major concern with supraglottic laryngeal surgery, especially intraoperative bleeding in TLM (52% in TLM vs 26% in TORS) (p = 0.09) and postoperative bleeding in TORS (56% in TORS vs 44% in TLM).
Conclusion:
The experts did not identify a clear superiority of one technology (TLM) over the other (TORS). The two techniques seemed equivalent to the experts, except for the control of intraoperative haemostasis and visualisation of the surgical field, where TORS was perceived as superior to TLM.
