The 3-dimensional exoscope is a safe and practical tool for stapes surgery, offering educational benefits for surgical teams and trainees. Audiological outcomes and complication rates were comparable to traditional microscope methods.

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Audiology

Background:

  • Stapes surgery for otosclerosis remains challenging despite advancements.
  • 3-dimensional exoscopes offer potential advantages in otological procedures.

Purpose of the Study:

  • To evaluate the role of 3-dimensional exoscopes in stapes surgery.
  • Assessing both surgical outcomes and educational benefits.

Main Methods:

  • Seven patients underwent laser stapedotomy using a 4K 3-dimensional exoscope.
  • Audiometry, complication rates, and operative times were collected.
  • Ergonomic and didactic evaluations were performed; a microscope group served as control.

Main Results:

  • Successful outcomes with significant air-bone gap reduction (26.5 to 10 dB).

  • No major complications reported; median operative time was 40 minutes.
  • Exoscope use improved operating room management and trainee confidence.

    • Conclusions:

    • The 3-dimensional exoscope is a safe, practical, and educational tool for stapes surgery.
    • Further validation against microscope and endoscope is needed.
