儿童感音神经性耳聋内耳多层螺旋CT特征及应用分析

摘要

目的 探讨儿童感音神经性耳聋内耳多层螺旋CT特征及应用分析.方法 选取自2016年3月5日至2017年3月5日该院接受治疗的儿童感音性耳聋患儿41例,共82耳,采用筛检试验观察多层螺旋CT和单层螺旋CT对内耳畸形诊断准确率,观察多层螺旋CT显示儿童感音性耳聋内耳特征.结果 多层螺旋CT诊断儿童感音性耳聋的灵敏度为87.72％,特异度为80.00％,约登指数为0.68;单层螺旋CT组诊断灵敏度为59.65％,特异度为68.00％,约登指数为0.28;多层螺旋CT组灵敏度显著高于单层螺旋CT组,差异有统计学意义(x2=4.31,P＜0.05).多层螺旋CT结果显示,前庭导水管畸形36例(63.2％)显著高于耳蜗畸形16例(28.1％),前庭畸形18例(31.6％),半规管畸形22例(38.6％),内耳道畸形16例(28.1％),差异有统计学意义(x2 =21.11,P＜0.05).结论 多层螺旋CT能够较完整的显示儿童感音性耳聋的内耳畸形结构,提供更加全面准确的诊断信息.%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.
