Two Cases of Auricular Burn Caused by the Operating Microscope Illumination System

Abstract

We describe two cases of burn caused by the operating microscope illumination system during a tympanoplasty. Cumulative risk factors such as strong light intensity, a short working distance, and dryness of the irradiated area induced irreversible tissue injury on the circumferential skin.
Although only a few reports have referred to this kind of iatrogenic injury, in the interest of patient safety even during routine medical procedures, we believe that recognition of all potential risks is an essential prerequisite for the prevention of iatrogenic events.
