There was no loss of quality when images were taken at lower light intensities during endoscopic ear surgery reported a new study published in Clinical Otolaryngology. Several clinical studies have evidenced the advantages of rapidly developing endoscopic ear surgery (EES). However, temperatures of over 110 ° C required for endoscope raises the safety concern.
Therefore, there is a need to study the effect of light intensity on image quality in EES. A Recent study of 20 patients undergoing EES demonstrated that mean scores for photographs at 10%, 30%, 50% and 100% light intensity were 3.22 (SD 0.93), 3.15 (SD 0.84), 3.08 (SD 0.88) and 3.10 (SD 0.86) respectively. Likewise, in ANOVA models for the scores on each of the scales such as anatomy; colour contrast; overall quality, and suitability for operating the effects of expert rater and patient were highly significant (p < 0.0005).…
