Question
The baby developed a hematoma due to head compression at birth. The doctor said it would disappear on its own, but after 40 days, the hematoma has not gone away and has become harder. Why is this? Has it calcified? Do I have to have surgery? Or can it disappear on its own?
Answer
The baby’s hematoma formed due to compression and friction of the head during childbirth, also known as a subcutaneous hematoma. During childbirth, when the head is compressed, regional blood circulation is obstructed, causing subcutaneous tissue edema. The doctor uses forceps or a vacuum extractor to assist in delivery, and when the fetal head is compressed, the skull overlaps, the head circumference decreases, potentially leading to subdural vascular injury and rupture. Blood gradually accumulates to form a hematoma. Typically, it takes about 3 to 4 weeks for the hematoma to gradually absorb and become smaller and harder. Some newborns may need more time, approximately 4 to 6 months before it completely absorbs and disappears. There’s no need to worry; the hematoma will not swell and will gradually absorb. Rapid absorption may take 1-2 weeks, while slow absorption may take 4-6 months. This type of hematoma does not affect the baby’s growth and development. As for whether surgery is necessary, it is recommended to consult with a professional doctor.
