Ozturan O, et al. - Researchers estimated the temperature changes witnessed during endoscopic ear surgery (EES) when using different calipers on static endoscopes fitted with camera holders during true operations. Further, they investigated the effects of varying light source intensities, as well as the cooling effect of irrigation and suction. Analyzing 12 patients with chronic otitis who underwent myringoplasty surgery using 2 of 5 different endoscopes with xenon light sources (4 mm–0°, 3 mm–0°, 2.7 mm–0°, 3 mm–45° and, 2.7 mm–30°), they suggest the safety of stationary use of endoscopes with 3 mm and smaller calipers without irrigation or aspiration, as the heat generated in the middle ear does not cause thermal trauma to tissue. Frequent aspiration or intermittent irrigation seemed to prevent potential thermal damage, even in procedures performed using endoscopes of a 4 mm caliper. They suggest opting light intensity settings of 50% as a further safety measure against potential thermal risk without compromising visual acuity.
