Medical Therapy
Medical management of torticollis involves conservative treatment.[12] Sternocleidomastoid fibrosis spontaneously resolves in the vast majority of infants. A large prospective study demonstrated that controlled manual stretching is safe and effective in the treatment of congenital muscular torticollis when a patient is seen before age one year.[13, 14] Physiotherapy may be recommended; however, little evidence shows that this alters the course of the condition if the patient is older than one year.
Botulinum toxin type A has been injected into the sternocleidomastoid muscle for the treatment of congenital muscular torticollis in pediatric and adult patients.[15] However, modest benefits with improved range of motion has been observed in very few patients.
Only about 4-5% of patients are surgically treated, generally after the age of 1 year.
Successful bilateral pallidal stimulation has been reported in a patient with Meige syndrome and spasmodic torticollis.[16]
Surgical Therapy
Patients whose pathology does not resolve after 12 months of physical therapy or who develop facial asymmetry or plagiocephaly during the follow-up period should undergo surgery to achieve the best cosmetic result.[17, 18] In delayed cases, additional surgery may be needed for the best cosmetic and functional result.
Surgery is performed with the patient under general anesthesia. A 3- to 4-cm transverse skin incision is made about 1 cm over the sternal and clavicular origins of the affected muscle. The platysma is carefully divided along the line of incision to avoid injury to the external jugular vein. The 2 heads of the sternocleidomastoid muscle are dissected free. The muscle is divided using diathermy to prevent bleeding. The platysma is then sutured with absorbable 4-0 skin suture, and the skin is closed with continuous 4-0 nonabsorbable skin suture.
An endoscopic or minimal access approach is being offered for the surgical treatment of torticollis. In this approach, muscular torticollis is surgically corrected via endoscopic tenotomy of the sternocleidomastoid muscle.[19]
Complications
Hematomas may develop because of inadequate hemostasis during surgery. Incomplete division may cause the condition to persist.
Outcome and Prognosis
Recurrent torticollis after surgery is rare, with a rate of approximately 5%.[20] Even in patients older than school age and those who have finished growth, sufficient unipolar or bipolar release of the sternocleidomastoid muscle and intensive postoperative care are expected to yield satisfactory treatment results.[21]
Secondary effects of untreated torticollis include plagiocephaly, facial hypoplasia, and musculoskeletal effects.
- Plagiocephaly is an asymmetric skull deformity in infants that is caused by the flattening of one occiput that leads to the secondary flattening of the contralateral forehead. After the torticollis resolves, the plagiocephaly resolves; however, several years may pass before it disappears.[22] Although torticollis can predispose to plagiocephaly without synostosis (PWS), torticollis appears to result from plagiocephaly in a large proportion of cases of plagiocephaly with scoliosis.[23]
- Facial hypoplasia is inhibition in the growth of the mandible and maxilla due to muscle inactivity. Clinically significant facial hemihypoplasia develops over 8 months; however, it is obvious in patients at the age of 2-3 years. Facial hypoplasia improves as the child grows, after the torticollis resolves.[24]
- Musculoskeletal effects include the compensatory ipsilateral elevation of the shoulder, as well as cervical and thoracic scoliosis. Wasting of additional muscles in the neck may be present due to sternocleidomastoid inactivity.
Future and Controversies
Follow-up should be continued until the torticollis resolves completely, until head and neck movement normalize, and until cervical and thoracic scoliosis is resolved in older children.
