Abstract: The purpose of this study was to investigate the relationship between quantitative parameters of high resolution CT (HRCT) and diffusion tensor imaging (DTI) parameters of auditory pathway in children with congenital sensorineural hearing loss (CSNHL). A total of 62 children with CSNHL were selected as the observation group, and 50 cases of children with normal hearing were selected as the control group, the HRCT and DTI parameters of each group were analyzed. The experimental results showed that:The length and width of cochlear canal and cochlear height of the observation group were significantly lower than those of the control group (P<0.05). The fractional anisotropy (FA) values of transverse temporal gyrus, superior temporal gyrus, posterior limb of internal capsule, auditory radiation and superior olivary nucleus in the observation group were significantly lower than those in the control group (P<0.05), the apparent diffusion coeffecient (ADC) values were significantly higher than those in the control group (P<0.05). The length and width of cochlear canal and cochlear height of the mild children in the observation group were significantly higher than those of moderate severe and extremely severe children (P<0.05), FA value and ADC value of hearing radiation were significantly lower than that of moderate severe and extremely severe children (P<0.05). The length and width of cochlear canal and height of cochlear were positively correlated with auditory radiation FA (P<0.05), and negatively correlated with ADC of auditory radiation (P<0.05). This study confirmed that some HRCT and DTI parameters of CSNHL with different severity are different, the length and width of the cochlear canal and the height of the cochlea are correlated with FA and ADC of auditory radiation.
