Abstract:
Objective To investigate the multi-slice spiral CT characteristics of inner ear in child sensorineural deafness and its application analysis.Methods A total of 41 children patients(82 ears) with sensory deafness treated in this hospital from March 5,2016 to March 5,2017 were selected.The screening test was adopted to observe the accuracy rate of multi-slice spiral CT and monolayer spiral CT for diagnosing the inner ear malformation.The inner ear characteristics in child sensorineural deafness revealed by multi-slice spiral CT were observed.Results The sensitivity of multi-slice spiral CT for diagnosing child sensorineural deafness was 87.72 ％,the specificity was 80.00 ％ and the Gordon index was 0.68;the diagnostic sensitivity and specificity in the single-slice spiral CT were 59.65 ％ and 68.00 ％ respectively,the Gordon index 0.28;the sensitivity of the multi-slice spiral CT group was significantly higher than that of the single-slice spiral CT group,the difference was statistically significant(x2 =4.31,P＜ 0.05).The multi-slice spiral CT results showed 36 cases(63.2 ％) of vestibular aqueduct abnormalities,which were significantly higher than 16 cases (28.1％) of cochlear deformity,vestibular deformity in 18 cases (31.6 ％),semicircular canal deformity in 22 cases(38.6％) and inner ear canal deformity in 16 cases(28.1 ％),the differences were statistically significant(x2 =21.11,P＜0.05).Coclusion Multi-slice spiral CT can more completely display the inner ear deformity structure to provide more comprehensive and accurate diagnostic information.
