Abstract：Objective: The diagnostic value of real-time shear wave elastography(SWE) to infants congenital muscular torticollis(CMT) and the clinical application of SWE in assessing the no-surgical treatment effect of children’s CMT were discussed. Methods: One hundred and two cases of suspected children with CMT(outpatient in our hospital from Jan. 2015 to June. 2017) were collected. All of them were examined by ultrasound and SWE was used to collect the elastic modulus data of sternocleidomastoid muscle on the affected side and the healthy side. After that, the children patients’ therapeutic process was followed up. The no-surgical treatment mainly includes massage and ultrasonic short wave physiotherapy. When a follow-up to three months was fulfilled, ultrasound reexamination was performed and the elastic modulus data of the children patients’ sternocleidomastoid muscle was recollected. Results: In the 102 cases of children patients, 76 cases were diagnosed with CMT. The area under ROC curve of diagnosing CMT by SWE was 0.844, and the diagnostic threshold was 182 kPa, and the sensitivity was 84.2%, and the specificity was 73.1%, and the positive predictive value was 90.1%, and the negative predictive value was 61.2%, and the Youden index was 0.573. To the children patients with CMT, a comparison of the elastic modulus data between sternocleidomastoid muscle on the affected side and the healthy side was performed, and the difference is statistically significant(P<0.05). Through the reexamination after no-surgical conservative treatment, the average elastic modulus value of sternocleidomastoid muscle on the affected side was significantly reduced, and the difference is statistically significant(P<0.05). Conclusion: Real-time SWE yields theoretical foundations to the diagnosis and the treatment effect evaluation of infants CMT. It embraces a certain value of popularization and application.
