Baby Head Tilt (Torticollis): Signs & Treatment

Many parents notice a baby head tilt in photos first. Their baby’s head always leans to one side, and the chin points the other way. Sometimes there is also a small hard lump low on one side of the neck. The baby feeds and smiles normally. This is most often congenital muscular torticollis (CMT), also called “wry neck”. The cause is a tight neck muscle, not an injury you missed. Most babies improve, and gentle stretching is the standard first treatment. Experts still debate how much of the improvement is due to the stretching itself. A small number need an operation. And a few head tilts have a different cause that needs a doctor quickly. Below is how to tell them apart.

What Is Congenital Muscular Torticollis?

One of the two big neck muscles that run from behind the ear to the collarbone, the sternomastoid muscle, becomes short and tight. It is partly replaced by firm scar-like tissue. The tight muscle pulls the head toward its own side and turns the chin toward the opposite side. It affects about 4 in 1,000 babies (1 in 250). The right side is affected in about 6 in 10 babies. Both sides are affected in about 2 to 8 in 100.

The exact cause is not proven. The textbook view today is that the muscle tightens before birth, probably from cramped space in the womb or poor blood flow to the muscle. This is why it is seen more often after a breech birth (in about 2 to 3 in 10 affected babies) or a difficult delivery (about 6 in 10). The older idea, that the muscle was torn at birth, is no longer favoured. In newborns the tissue is already mature, which means it formed before labour began. Nothing you did after birth caused this.

What Parents Notice in a Baby Head Tilt and When

The tilt is rarely seen on the day of birth. It usually shows between 1 and 3 weeks of age and sometimes up to 6 to 8 weeks. You may see:

A head tilt to one side, with the chin turned to the other side.
A firm, painless, lump about 1 to 3 cm in the muscle, in about 3 to 6 in 10 babies. Doctors call this a “sternomastoid tumour”. It is not a cancer. It is a knot of scar-like tissue. It grows for a few weeks and then slowly shrinks.
The baby turns the head easily to one side, and less far toward the tight side.
A flat spot on the back of the head on the side the head rests on (plagiocephaly), which is common.
In some babies, no lump at all, only a tight muscle or only a head tilt.

A baby with torticollis should also have the hips checked. About 7 to 12 in 100 babies with torticollis also have developmental dysplasia of the hip (a loose hip joint), since both can come from the same cramped position before birth. Your doctor may do a hip examination or a hip ultrasound.

How Doctors Check a Baby Head Tilt

Usually the doctor makes the diagnosis by history and examination alone. An ultrasound of the neck is the first scan if there is any doubt. It shows the thickened muscle and tells it apart from a lymph gland, a cyst or another lump. A lump in a typical position, in a baby with a typical head tilt, does not need a biopsy or a CT scan.

Baby Head Tilt Treatment: Stretching Comes First

Stretching and positioning are the first treatment. Your doctor or a physiotherapist shows you how. In general:

Gentle stretches 2 to 4 times a day, about 5 to 10 minutes each. Hold the shoulders flat. Slowly turn the head toward the tight side, and tilt the ear toward the shoulder on the opposite side. Never force it, and ask your doctor or physiotherapist if your baby seems to be in pain.
Tummy time while awake and watched. It strengthens the neck and takes pressure off the back of the head.
Make your baby look toward the tight side. Place toys, a mobile or the light on that side. Hold and feed in positions that make the chin turn that way.

How well does it work? The outlook is good, and it depends on how early you start. In some studies, 9 in 10 or more babies are cured by stretching when it starts early. Babies who start before 3 months do best. The chance of needing surgery rises with age at the start of treatment: about 1 in 4 who start at 3 to 6 months, and most of those who start after 6 months. Physiotherapy is credited with this success, but not every expert agrees. Some say that many babies improve with time anyway, because about 5 to 7 in 10 settle by 6 months even without special treatment. In either case, do not wait to see: seeing a doctor early costs little and protects against the problems listed below.

Most babies need 3 to 4 months of stretching, and sometimes up to a year. A moulding helmet treats only the flat head shape in babies whose shape does not improve with repositioning. It does not correct the tight muscle. Botulinum toxin injections into the muscle are still considered experimental. They are sometimes tried for a tight muscle that has not responded, and they work less well once the muscle is scarred. Both are for your surgeon to advise on.

When Is an Operation Needed?

Only a minority need surgery. About 1 in 10 babies still have a tight muscle after the first year, and these are the ones who need an operation. Babies seen late are more likely to need it. The usual reasons are:

The tight muscle still limits head turning after about 6 months of proper stretching, or by 12 to 15 months of age.
The face is becoming uneven (see below).
The child is first seen after the age of 1 year.

In the operation, the surgeon divides the tight lower end of the sternomastoid muscle, and the tight sheet of tissue around it, under direct sight. This is done carefully to protect the nerve that supplies the shoulder muscles and the nerves of the arm. It is usually done as a day-case. Your surgeon will advise on exercises afterwards. The main risks are bleeding under the skin (a haematoma) and a tilt that stays if the muscle or its sheath was not fully released. Coming back is uncommon, in fewer than 3 in 100.

Why not leave it? If a tight muscle is left for years, the face can grow unevenly. Normal facial bone growth depends on normal muscle movement. On the tight side, the cheekbone is flatter, and the eye, ear and mouth sit lower. Older children also lift one shoulder to keep their eyes level, which can twist the spine. Facial change is hard to see in the first months, but becomes clearer after 6 months to a few years. Releasing the muscle can restore normal growth, and this is why timing matters.

When a Baby Head Tilt Is Not CMT

About 2 in 10 children with a head tilt have a cause other than the sternomastoid muscle. Most are harmless, but some are urgent. See a doctor quickly if you notice any of these:

A squint or eye problem. A child may tilt the head to see clearly. If the eyes look uneven when the head is gently straightened, ask for an eye specialist review.
A neck that suddenly will not move, often after a throat or upper airway infection, a throat operation or a minor injury. This can be a slipped joint at the top of the spine. It needs a scan.
A stiff, painful “frozen” neck with morning headaches, vomiting, unsteady walking or weakness. This can be a growth in the back of the brain and needs an urgent MRI.
Fever, drooling, trouble swallowing or a very unwell child. This can be an infection deep in the neck.
Head tilt with arching and spells of crying after feeds, with vomiting or poor weight gain. This can be a sign of severe reflux (Sandifer syndrome).
A short neck with a low hairline, which can point to fused neck bones (Klippel-Feil syndrome). Your child may need an X-ray of the neck spine.
Turning the head toward one side to hear better. A hearing test is advised if the muscle is normal.

What Every Parent Must Know

A head tilt with a firm neck lump in a young baby is usually congenital muscular torticollis. The lump is not a cancer.
Start gentle stretching and tummy time early, once a doctor has shown you how. The earlier you start, the better it works.
Have your baby’s hips checked.
If the tilt is still there after 6 months of stretching, or if the face looks uneven, see a pediatric surgeon. Surgery is a short day-case operation.
A stiff, painful neck, headache with vomiting, or fever with a head tilt needs a doctor the same day. A squint needs an eye review soon.

When to See a Doctor

See a doctor soon if your baby has a constant head tilt, a neck lump, a flat head, or a squint. See a doctor the same day for a sudden stiff neck, a painful neck with fever, headache with vomiting, unsteady walking, or a head tilt with trouble swallowing.
