Abstract

OBJECTIVE:

We assessed the surgical results of bipolar release in 31 adult patients with uncorrected congenital muscular torticollis (CMT) and more than 12 months of follow-up.

METHODS:

Thirty-one patients underwent a bipolar release of the sternocleidomastoid muscle (SCM) and were retrospectively analyzed. The mean follow-up period was 14.9 months (range, 12-30). The mean age at time of surgery was 30.3 years (range, 20-54). Patients were evaluated with a modified Lee's scoring system, cervicomandibular angle (CMA) measurement, and a global satisfaction rating scale using patient self-reporting.

RESULTS:

The modified Lee's scoring system indicated excellent results in 4 (12.9%) patients, good in 18 (58.1%), and fair in 9 (29.0%) at the last follow-up after surgery. The improvements in neck movement and head tilt were statistically significant (p<0.05). The preoperative mean CMA was 15.4° (range, 5.4-29.0), which was reduced to a mean of CMA of 6.3° (range, 0-25) after surgery (p<0.05). The global satisfaction rating scale was 93.7% (range, 90-100). A transient sensory deficit on the ipsilateral lower ear lobe was noted in three cases. No significant permanent complications occurred.

CONCLUSION:

Bipolar release of the SCM is a safe and reliable technique for the treatment of CMT in adults.
