    The study evaluated the technical feasibility and ergonomic advantages of the 4K three-dimensional exoscope system in stapedotomy.

  • 2

    A total of 140 stapedotomy procedures were analyzed, with 52 using the 4K3D-ES and 88 using the operative microscope.

  • 3

    Results showed no significant differences in operative time, intraoperative blood loss, or audiometric outcomes between the two systems.

  • 4

    The 4K3D-ES system achieved complete procedural success without conversion to the operative microscope and had an excellent safety profile.

  • 5

    Surgeons reported superior ergonomics and image quality with the 4K3D-ES, enhancing intraoperative collaboration and comfort.
