Background: In prior studies, there has been no report of clinical observation of postoperative reconnection of the sternocleidomastoid muscle (SCM) in children with congenital muscular torticollis (CMT). Therefore, the objective of this study is to investigate the factors associated with postoperative reconnection of the SCM in children with CMT, and to provide clinical evidence.
Methods: A retrospective study was conducted, wherein 83 CMT children without any missing data were followed up from November 2019 to June 2021. The age at the time of surgery, sex, preoperative and postoperative follow-up duration, laterality, neck mass history, preoperative physical therapy history, and severity type were recorded. The severity classification of CMT was based on clinical features and ultrasound images of SCM. The postoperative reconnection of SCM was measured.
Results: Out of 83 patients, ten had postoperative reconnection. The rate of postoperative reconnection of SCM in children with CMT who had undergone unipolar SCM release surgery was 18.994 times higher than in patients who had not undergone such surgery. This difference was statistically significant [odds ratio (OR) =18.994, 95% confidence interval (CI): 1.583 to 227.897, P=0.020].
Conclusions: The history of SCM release surgery in CMT children can predict the postoperative reconnection of SCM, which will aid in determining the optimal surgical approach for recurrent CMT patients.
