Introduction:The role of objective parameters in terms of improvement of the accuracy of highresolution computed tomography(HRCT)of the temporal bone in the diagnosis of otosclerosis remains ***:To investigate the relationship between the density of the fissula antefenestram(FAF)and of the width of the transversal section of the basal turn of the cochlea(BTC),and the diagnosis of ***:This is a retrospective study in which preoperative HRCT data from ears of patients submitted to stapedotomy due to otosclerosis(case group)were *** the control group,normal hearing ears having undergone HRCT for other purposes were *** and control HRCT images were objectively assessed by an experienced blinded *** this evaluation,measurements of the relative radiological density of the FAF and of the transversal section of the BTC were *** results were compared between the ***,a receiver operating characteristic curve was created and the area under the curve(AUC)was calculated for each *** level was set ***:40 ears were included in each *** ears presented reduced values for the relative radiological density on the FAF(p-value<0.0001).Moreover,ears with otosclerosis(p-value:0.022)presented lower transversal section of the *** AUC for these variables reached 0.929 and 0.646,***:Otosclerotic ears present reduced radiological density on the FAF and narrower *** relative density of the FAF also shows a great diagnostic power in the context of this disease.
