超声四分型法在先天性肌性斜颈诊断中的应用价值

Clinical value of ultrasound quarter-type method for congenital muscular torticollis

目的探讨先天性肌性斜颈(CMT)超声四分型法的临床价值。方法本院收治的67例CMT患儿,根据超声表现分为四型;并进一步研究患儿年龄、胸锁乳突肌厚度比率与分型之间的相关性,以及各型病变彩色多普勒表现是否存在差异。结果患儿年龄与超声分型之间相关系数为0.758;胸锁乳突肌厚度比率与超声分型之间相关系数为0.411。26例病变肌肉内彩色多普勒探及血流信号,其中Ⅰ型18例(18/32),Ⅱ型8例(8/15),Ⅲ型和Ⅳ型患儿患侧胸锁乳突肌均未测到血流信号。结论先天性肌性斜颈超声表现具有特征性,建立在超声成像基础上的四分型方法能反映疾病的演变过程,有助于临床诊断、治疗及判断预后。

Objective To investigate the clinical value of ultrasound Quarter-type method for congenital muscular torticollis（CMT）.Methods Sixty-seven children with congenital muscular torticollis were divided into four types according to ultrasonic appearance.The correlations between children age,thickness ratio of sternocleidomastoid muscle（SCM）and typing were studied.Color Doppler flow imaging（CDFI）performance in all types were researched.Results The correlation coefficient between children age and ultrasonic typing was 0.758.The correlation coefficient between SCM thickness ratio and ultrasonic typing was0.411.CDFI displayed blood flow signal in lesion muscles in 26 cases,including 18 cases in type Ⅰand 8 cases in type Ⅱ.SCM in lesion side was not detected blood flow in type Ⅲ and Ⅳ.Conclusion Congenital muscular torticollis has characteristic ultrasonic appearance.Quarter-type method based on ultrasound imaging can response evolution process of the disease and help to clinical diagnosis,treatment and assessing prognosis.
