New surgical frontiers for 4K 3D-exoscope in paediatric head and neck surgery.

PURPOSE: To define the interest, advantages, and disadvantages of the use of a 3D-exoscope in paediatric ENT surgery. METHODS: Four surgeons with experience in paediatric surgery completed a questionnaire following each surgery performed under 3D-exoscope to evaluate the contribution of the tool compared to the usual practice (microscope or magnifying loupes). Surgeries were separated into three groups: otology, transoral and cleft palate surgery, and open head and neck surgery. RESULTS: Between June 2021 and June 2022, 151 paediatric surgeries were included in this study. Among them, 93 (62%) otologic surgeries, 35 (23%) transoral surgeries, and 23 (15%) head and neck surgeries were performed. The median age at surgery was 68 months (interquartile range 19-135 months). For otologic surgeries, the mean scores (/100) for the contribution of the exoscope compared to the microscope were 68.4(+/- 23.2). For transoral and cleft palate surgery, the mean score (/100) for the contribution of the use of the exoscope compared to the magnifying loupes was 92.9 (+/- 8.6), whereas for open head and neck surgeries, the mean score (/100) was 89.5 (+/- 7.2). CONCLUSION: 3D-exoscopy appears to be a relevant tool for paediatric head and neck surgery, applicable in otologic, transoral, and cervical fields. It presents educational and ergonomic advantages and improves surgical team communication.
