Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Infectious Disease Control

Background:

  • The World Health Organization declared COVID-19 a global pandemic, necessitating enhanced safety measures in healthcare.
  • Mastoidectomy is an aerosol-generating procedure posing a significant risk of infectious particle exposure to surgeons.
  • Urgent otological surgeries in untested patients require immediate surgical intervention with robust protective protocols.

Purpose of the Study:

  • To design and prototype a cost-effective barrier device for mastoidectomy procedures.
  • To mitigate the risk of airborne particle transmission during mastoidectomy in the context of COVID-19.

Main Methods:

  • Development of a low-cost barrier device for particle dispersion during mastoidectomy.
  • Integration of the barrier with surgical instrumentation and microscope use.
  • Evaluation of the device's performance in an otologic emergency setting.

Main Results:

  • The prototype barrier did not impede surgical field visualization or instrument manipulation.
  • The device allowed for microscope repositioning without limitation.
  • Post-surgery, the barrier was easily removed, and it successfully collected bone dust and irrigation droplets.

Conclusions:

  • A low-cost, reproducible barrier device for mastoidectomy in COVID-19 patients was successfully developed and tested in an emergency setting.
  • The device offers a practical solution for protecting surgical teams during high-risk procedures.
  • Further studies are recommended to validate the efficacy of this barrier device.
