If your baby was born with assistance, such as using a suction cup, you might notice a swelling on their head in the shape of the suction cup. This condition is known as a cephalohematoma. In this blog post, we'll delve into what a cephalohematoma is, how common it is, and what factors make your baby more likely to develop one. We'll also look at examples of cephalohematomas, discuss whether treatment is needed, and cover some potential complications.

A cephalohematoma occurs when blood collects between a newborn's scalp and their skull. The term may sound complex, but let's break it down: "cephalo" refers to the head, and "hematoma" means a collection of blood outside blood vessels. This type of birth injury happens when pressure on a baby's head during delivery ruptures blood vessels in the scalp. The blood then pools beneath the scalp, forming a soft bulge that eventually hardens or calcifies. The lump often shrinks from the center first, giving it a ring-shaped or crater-like appearance.

So, how common is cephalohematoma? According to available data, cephalohematomas occur in about 2.5% of prolonged, difficult vaginal deliveries. If a woman has an assisted delivery requiring vacuum extraction or forceps, the risk increases to about one in ten babies delivered this way. Other factors can also elevate the risk, such as epidural pain relief during childbirth, having a long labor, delivering larger-than-average babies (known as fetal macrosomia, weighing more than eight pounds, 13 ounces), and having multiple babies, such as twins or triplets.

Let's take a closer look at some examples of cephalohematomas. In the photos provided, taken three to four days after delivery, you can see a cephalohematoma on the back left side of the baby's head. This particular hematoma has taken the exact form of a suction cup, indicating that the baby was delivered using a suction cup or vacuum extraction. In most cases, the diagnosis is made clinically by a doctor assessing the baby. However, in rare instances where there might be concern about a skull fracture, imaging such as an MRI (magnetic resonance imaging) may be requested.

Many parents wonder if treatment is necessary for cephalohematomas. The most common answer is no. Cephalohematomas are often harmless, and the bruising or blood buildup typically resolves on its own within a few weeks to a couple of months.

However, it is essential to be aware of potential complications, although they are rare. Most cephalohematomas settle down without any long-term issues, but there are some exceptions. These include:

1. **Anemia**: A drop in red blood cells can occur because a cephalohematoma can take blood away from the baby's circulatory system.
2. **Calcifications**: Cephalohematomas that last more than five weeks may form hardened bone deposits known as calcifications around the mass.
3. **Infections**: Cephalohematomas are more prone to infections, though this is rare.
4. **Jaundice**: As the baby's body absorbs the blood from the cephalohematoma, bilirubin levels in the bloodstream can rise, causing jaundice. The baby's skin or eyes may take on a yellow tint, and healthcare professionals will monitor this closely.
5. **Skull Fracture**: As many as one in four babies with cephalohematomas may have a linear skull fracture. While this might sound alarming, a linear fracture does not move the bones in the skull and usually heals over time without treatment.

In conclusion, cephalohematomas are relatively common in assisted deliveries and typically resolve without any need for treatment. While complications are rare, it's essential to be aware of them and consult with your healthcare provider if you have any concerns.
