Summary
A novel, low-cost barrier device was developed for mastoidectomy procedures during the COVID-19 pandemic. This prototype effectively contains infectious particles, ensuring surgeon safety without compromising surgical visualization or instrumentation.
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.
