Recovery time for hematomas on the head of newborns, known as cephalohematomas, varies depending on the size and extent of the scalp hematoma. Generally, hematomas take 6 to 8 weeks to resolve, and prolonged resolution may occur for larger hematomas. Hematomas in the head of newborns are usually caused by rupture of subperiosteal blood vessels during delivery, and blood accumulates under the periosteum, which is called cephalohematoma. The site of the hematoma is mostly found at the top of the head, and it is often one-sided, while a few may appear bilaterally. The hematoma often gradually increases in size in the first few hours to a few days after birth, but it does not usually go beyond the bony suture. Hematoma mechanism usually starts at the edge and gradually reaches the central part of the hematoma. It is usually considered that its absorption time, i.e., the time to subside, takes 4-6 weeks, and for larger hematomas, it may take 3-4 months. It is important to be aware of the possibility of secondary infections, which need to be evaluated by specialists, and surgical incision and drainage are needed if necessary. It is recommended to consult a specialist as soon as possible for a comprehensive assessment and targeted treatment.
