Congenital muscular torticollis: Use of gaze angle and translational deformity in assessment of facial asymmetry.

Background: Assessment of facial asymmetry is challenging in torticollis deformity. Neck tilt in toroticollis is associated with deviation of horizontal ocular gaze and translation of neck from the midline. These deviations can be assessed clinically and can be used as surrogate marker for facial asymmetry.
