Preliminary Experience with 3‐Dimensional Exoscope‐Assisted Laryngoplasty.

Objective: Laryngoplasty requires the manipulation of the vocal folds, which are not visible during the operation. The widespread use of this technique is limited by the need for adequate knowledge of anatomy, the small surgical field, and the high level of skill required for the procedure. An exoscope has been developed to provide a stereoscopic view similar to that of a microscope while using the same compact endoscopic tool. This study aimed to determine whether the three‐dimensional (3D) exoscopic surgical technique could be applied to laryngoplasty and explore its possibility to ultimately replace the current approach. Methods: This was a retrospective case series analysis, which included 28 patients with hoarseness who underwent surgery with (Exoscope; n = 12) or without (Macrosurgery; n = 16) a 3D exoscope between July 2018 and February 2021. The feasibility of performing all surgical steps with the 3D exoscope was evaluated. The Exoscope and Macrosurgery groups were compared for surgical time, vocal function outcomes, and complications. Questionnaires were completed by medical staff regarding the usefulness of medical education. Results: No intraoperative or postoperative complications occurred in either procedure. The operative time was similar in both groups. The vocal function outcomes were also comparable between the groups. Questionnaires revealed that the exoscope was useful in terms of sharing information on surgical procedures and anatomy, as well as functioning as an educational tool. Conclusion: While this was a preliminary study, our results indicated that the exclusive use of the 3D exoscope was feasible for open approaches.
