Congenital Torticollis
Congenital torticollis is a condition seen in infants where a baby’s head tilts to one side and rotates to the opposite side. It is caused by tightness or shortening of a muscle in the neck called the sternocleidomastoid muscle (SCM). This muscle runs from behind the ear to the collarbone and breastbone and plays an important role in head movement.
When the SCM is tight, it pulls the head into an abnormal position. If left untreated, torticollis can lead to facial asymmetry, skull flattening (plagiocephaly), and limitations in neck motion as a child grows.

Etiology (Why it Happens)
The exact cause of congenital torticollis is not always known, but several factors are believed to contribute:
- Positioning in the womb that places pressure on the neck
- Limited space during pregnancy
- Birth trauma or difficult delivery
- Reduced blood flow to the SCM before or during birth
- Fibrosis (scarring) within the muscle
These factors can lead to shortening or thickening of the SCM, sometimes forming a small firm mass known as a “sternocleidomastoid tumor,” which is benign and resolves over time.
Presentation (How It Appears)
Parents often notice torticollis within the first weeks of life. Common signs include:
- Head consistently tilted to one side
- Chin rotated to the opposite side
- Preference for looking in one direction
- Limited neck range of motion
- Flattening of one side of the head
- Facial asymmetry if untreated
Early recognition is important, as treatment is most effective when started in infancy.
Conservative Treatment: Physical Therapy
The first line of treatment for congenital torticollis is non-surgical.
Most infants respond extremely well to:
- Stretching exercises
- Positioning techniques
- Strengthening therapy
- Supervised physical therapy programs
Parents are taught exercises to perform at home, and many babies achieve full correction with consistent therapy. Early intervention leads to the best outcomes and avoids the need for surgery in the vast majority of cases.
Surgical Treatment (When Therapy Is Not Enough)
If torticollis persists despite adequate physical therapy, surgery may be recommended. Surgical treatment focuses on releasing the tight sternocleidomastoid muscle to restore normal neck motion and head position.
Surgery is typically considered when:
- There is persistent restriction of motion
- Head tilt remains despite prolonged therapy
- Facial asymmetry is developing
- The child is older and conservative treatment has failed
The procedure involves carefully lengthening or releasing the SCM. It is performed with attention to both function and cosmetic outcome. After surgery, physical therapy continues to retrain the muscle and maintain the improved range of motion.
When performed at the appropriate time, surgical treatment can dramatically improve head position, symmetry, and long-term function.
Why Early Evaluation Matters
The earlier torticollis is diagnosed and treated, the better the outcome. Most children improve with therapy alone, but timely specialist evaluation ensures that children who need surgical treatment receive it at the optimal stage of development.
