Abstract

AbstractObjectivesThis study investigates the possible benefits and limitations of the digital image enhancement systems provided by Storz Professional Image Enhancement System (SPIES) during endoscopic ear surgery (EES) for cholesteatoma. An increased detection of cholesteatoma residuals during the final steps of endoscopic surgery using DIE technology was hypothesized.DesignCross‐sectional study.SettingTertiary referral hospital.MethodsA total of 10 questionnaires of 18 intraoperative pictures with equal numbers of cholesteatoma and non‐cholesteatoma images, each presented in three different image‐enhancing modalities (Clara, Spectra A, Spectra B), were generated. Fifty‐one experienced ear surgeons participated to the survey and were randomly assigned to a questionnaire and completed it at two time points. The experts were asked to rate for each picture whether cholesteatoma was present or not. The answers were compared with the histopathological reports.ResultsClara showed the highest accuracy in cholesteatoma detection, followed by Spectra A and lastly Spectra B. In contrast, Spectra B showed the highest sensitivity and Clara the highest specificity, while Spectra A was placed in the middle for both values. Using the Spectra B modality, most responses agreed across the two time points. Ear surgeons assessed the usefulness, as well as preference among image modalities for cholesteatoma surgery, in the following order: Clara, Spectra B, Spectra A.ConclusionDigital enhancement technologies are applicable to EES. After complete cholesteatoma removal, Spectra B showed the highest sensitivity in the detection of cholesteatoma residuals as compared with Clara and Spectra A. Thus, Spectra B may be recommended to avoid missing any cholesteatoma residuals during EES.
