Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Medical Imaging

Background:

  • Magnified visualization is crucial for safe and successful ear surgery.
  • Technological advancements have evolved magnification from monocular to digital 3D systems.
  • New technologies aim to improve visualization quality and surgeon ergonomics.

Purpose of the Study:

  • To evaluate the usability of a novel 3D exoscope system in common otological surgeries.
  • To assess the feasibility of this new technology for procedures like cochlear implantation and stapedectomy.
  • To determine if the exoscope meets the demands of microsurgery, particularly in the context of COVID-19 safety measures.

Main Methods:

  • A 3D camera mounted on a robot arm with hands-free control via surgeon-worn goggles was utilized.
  • The exoscope system was evaluated for the first time in patients undergoing cochlear implantation and stapedectomy.
  • Sterile draping procedures were employed to maintain a barrier between the patient and surgical personnel.

Main Results:

  • The 3D exoscope system demonstrated hands-free operation and sterile draping capabilities.
  • The technology was assessed for its potential to reduce aerosolization of drill rinsing water during surgery.
  • Subjective evaluation indicated that the image quality is equivalent to conventional microscopes for safe otologic surgery.

Conclusions:

  • The evaluated 3D exoscope system is a viable new technology for otologic microsurgery.
  • This exoscope offers potential advantages for performing elective hearing restoration surgeries safely, especially during pandemics.
  • The system provides high-quality visualization comparable to traditional microscopes, ensuring surgical safety and potentially improving surgeon ergonomics.
