Nasal Endoscopes May Cause Thermal Injury

What are the temperature variations of nasal endoscopes, and do older scopes reach higher temperatures?

Background: Although advances in endoscopic technology have improved illumination and light transmission, there may be greater heat production that places patients at risk for thermal injury, especially when endoscopic equipment comes into direct contact with the tissue of otolaryngology patients. Additionally, older scopes may reach higher temperatures as a result of less efficient light transmission.

Study design: Observational study.
