During childbirth, there is a small chance that a baby may experience a birth injury. One type of injury that can occur is a cephalohematoma.
A cephalohematoma is a collection of blood that forms between the skull bone and the outer covering of the skull, known as the periosteum. It typically appears as a raised bump on the baby’s head, often noticeable a few hours after birth. Cephalohematomas are more common in vaginal deliveries and can occur due to trauma during the birthing process.
How clinicians identify newborn cephalohematoma
A cephalohematoma often isn’t fully visible right at birth. It can take several hours, sometimes a day, before the swelling reaches its largest size, since subperiosteal blood collects gradually beneath the periosteum. One feature clinicians look for is that the swelling stays confined to the borders of a single skull bone, unlike other scalp swelling that crosses those boundaries. Over the following days, the once-soft lump often firms up as the body reabsorbs the blood.
Because several types of newborn head swelling from birth trauma can look similar, clinicians rely on clinical evaluation to distinguish a cephalohematoma from caput succedaneum, a softer swelling that crosses suture lines and resolves within days, and from subgaleal hemorrhage, a rarer condition involving bleeding across a wider space beneath the scalp. Telling these apart usually requires a hands-on exam, not a visual check alone. Any changing swelling after delivery deserves prompt evaluation by the baby’s provider.
Causes and risk factors
Cephalohematomas are usually caused by pressure on the baby’s head during delivery. This can happen if the baby’s head becomes pressed against the mother’s pelvis. While cephalohematomas can impact any baby, certain factors may increase the risk, such as a larger baby size, a prolonged or difficult delivery or the use of forceps or vacuum extraction.
According to data published by the National Center for Biotechnology Information, cephalohematomas occur with an incidence of 0.4 to 2.5% of live births.
Potential complications and treatment
In most cases, cephalohematomas are not a cause for major concern. The blood within the hematoma is gradually absorbed by the body over several weeks, and providers monitor the baby for a handful of specific concerns during that time. As the blood breaks down, it can contribute to jaundice, so providers watch the baby’s skin and eye color. Larger hematomas carry a small risk of anemia, and any break in the skin raises the possibility of infection.
Providers may also check for an underlying skull fracture or, later, a firmer rim of calcification as the swelling resolves. Feeding, alertness, and swelling size are tracked over time.
For parents or caregivers, it is natural to have concerns when a baby experiences a birth injury like a cephalohematoma. Staying in close contact with the baby’s pediatrician during the monitoring period is the best way to catch any complications early.
When a newborn’s cephalohematoma follows a forceps delivery, vacuum-assisted delivery, or a prolonged delivery, Charlotte families in Mecklenburg County and across North Carolina are often left with questions.
The first step is typically pediatric guidance. Keeping birth records, delivery notes, and follow-up documentation matters if questions later arise.
Consulting a Charlotte birth injury lawyer or Charlotte medical malpractice representation is worth pursuing only when the facts suggest preventable harm, not because forceps delivery or vacuum extraction alone was used.
Frequently Asked Questions
Q: Can a cephalohematoma cause brain damage?
A: No. The blood collects outside the skull itself, between the bone and its covering, so it typically does not injure the brain. That said, other types of scalp swelling or associated injuries can carry different risks, which is why any swelling after delivery should be evaluated by the baby’s medical provider.
Q: How is cephalohematoma treated in newborns?
A: Observation is the most common approach, since most cephalohematomas resolve on their own without any intervention. During that time, clinicians monitor the baby for jaundice, anemia, infection, or other complications. Treatment, if needed at all, depends entirely on what those findings show for that specific newborn.
Q: How long does it take for newborn cephalohematoma to go away?
A: Recovery generally takes several weeks to a few months, though this varies by size. The lump may temporarily feel firmer as calcium builds up at its edges during healing. Parents should tell their pediatrician about any swelling that keeps growing or hasn’t started shrinking.
Q: What is the most common complication of cephalohematoma?
A: Jaundice is the most frequently seen complication, since the breakdown of collected blood can raise bilirubin levels in the newborn. Anemia and infection are less common but worth watching for too. Parents should ask their pediatric provider about skin color, feeding, and alertness at follow-up visits.
