Abstract

PURPOSE
This study aimed to evaluate any correlation between the volume of a lesion or physical training, and regression time, in congenital torticollis patients.
MATERIALS AND METHODS
From January 2007 to December 2010, 63 infants and young children underwent neck ultrasound (US), as congenital torticollis was clinically suspected. We statistically analyzed the correlation between the volume of a lesion or physical training and the regression time, when successful regression was defined as no visible lesion on follow-up US, or no palpation of the lesion on clinical follow-up.
RESULTS
Among 63 patients, 48 were sonographically diagnosed with congenital torticollis: normal delivery (n = 39) and c-sec (n = 9). Among them, 24 were clinically followed up, and 22 showed complete regression. Among 24 patients, 9 underwent physical training, and 7 showed complete regression after physical training. There was a negative correlation between the volume of a lesion and the regression time (p = 0.011), but there was no statistical significance between physical training and the regression time (p = 0.15).
CONCLUSION
In congenital torticollis patients, the volume of a lesion was in reverse proportion to the regression time, and physical training may be unhelpful for a decrease in regression time.

  • Fig. 1 Successful regression of congenital muscular torticollis in 1-month-old boy. A, B. On initial neck ultrasound, longitudinal (A) and transverse (B) images show localized enlargement of sternocleidomastoid muscle and higher echogenicity than adjacent normal sternocleidomastoid muscle. C, D. On follow-up neck ultrasound obtained 5 months after physical therapy, longitudinal (C) and transverse (D) images show normal thickness and echogenicity of sternocleidomastoid muscle.

  • Fig. 2 Unsuccessful regression of congenital muscular torticollis in 4-month-old boy. A, B. On initial neck ultrasound, longitudinal (A) and transverse (B) images show localized enlargement of sternocleidomastoid muscle and higher echogenicity than adjacent normal sternocleidomastoid muscle. C, D. On follow-up neck ultrasound obtained 12 months after physical therapy, longitudinal (C) and transverse (D) images show slightly decreased lesion.
