Applying the technology ORBEYETM exoscope in transoral exoscopic laryngeal surgery: single centre prospective study.

Abstract

Introduction: ORBEYE^TM exoscope offers superior visualization with clearer imaging compared to standard methods and supports narrow band imaging (NBI). ORBEYE^TM provides better visualization of tissue structures, thus increasing the accuracy of the surgical procedure. The systematic use of ORBEYE^TM in transoral exoscopic laryngeal surgery (TOLES) is rarely documented. This study evaluates the sensitivity and specificity of TOLES using ORBEYE^TM with white light and NBI modalities.

Methods: Between 8/2021 and 8/2024, 84 patients underwent TOLES using ORBEYE^TM with white light and NBI modes. All surgeries were performed in a specialized setting with consistent preoperative and intraoperative imaging protocols.

Results: TOLES using ORBEYE^TM was successfully performed in all 84 patients. A statistically significant dependence (p < 0.001) was observed between preoperative/perioperative (TOLES) findings and definitive histology for both white light and NBI modalities. ORBEYE^TM facilitated detailed imaging of tissue structures and allowed targeted biopsies.

Conclusion: TOLES with perioperative NBI/white light endoscopy achieved a high correlation between pre-histopathological diagnoses and final histopathological results. ORBEYE^TM exoscope provides three-dimensional 4K resolution, superior imaging, and improved ergonomics for the surgeon, reducing workload and increasing efficiency. It delivered more efficient surgical team collaboration and experience sharing. The integration of NBI into the TOLES system facilitated accurate navigation and targeting of the biopsy, helping to establish correct definitive diagnosis. TOLES showed more accurate scoring of perioperative NBI findings.
