Abstract：Objective To investigate the value of cochlear diameter assessed on high resolution CT(HRCT)in diag-nosis of sensorineural hearing loss(SNHL).Methods We compared temporal bone HRCT images between 58 SNHL cases (116 ears)with roughly normal inner-ear structure(SNHL group)and 129 cases(258 ears)without inner-ear malformation (control group).The ages of both groups were 0-36 months.The height of cochlear top and middle turn,length and canal di-ameter of cochlear basal turn were measured,then two sets of measurements were compared with t-test.Results The SNHL group preented cochlear abnormalities on temporal bone HRCT.The height of cochlear top and middle turn,length and canal diameter of cochlear basal turn in the control group were higher than those in the SNHL group(2.42±0.23 vs.2.71±0.19 mm;7.75 ±0.52 vs. 8.36 ±0.38 mm; 1.16 ±0.15 vs. 1.33 ±0.09 mm, respectively; all P<0.001). Conclusion For children with SNHL but roughly normal inner-ear structure on temporal bone HRCT,the quantitative cochlear measurement on HRCT is helpful to detect structural abnormalities,and it is of high value in diagnosis of SNHL.
