Cephalhematoma and serosanguineous bosa are medical conditions that appear in newborns in more difficult births. They are located at the level of the skull, but are not considered medical emergencies nor risks to the health of the baby. There are conditions that do not require a specific treatment because they withdraw themselves.
Cephalhematoma is an accumulation of blood that appears beneath the scalp in newborns extracted with its forceps or by vacuum extraction at birth. And other children who suffer various pressures in the birth canal may manifest this condition.
Cephalhematomas are like swellings that appear on the lateral parts of the skull (uni or bilateral). These are formed due to the rupture of blood vessels between the bony cap and scalp. In most cases it appears unilaterally, only on one side of the head.
They do not constitute medical emergencies nor do they in any way endanger the health of the fetus. They usually recover by themselves in about 2 weeks. Sometimes they can disappear and in less than 1 week, sometimes the evolution is slower and can last for 1 month.
When the cerebrospinal fluid and its blood are resorbable, bilirubin can be released which is released into the bloodstream. In some cases, this can have adverse effects, producing jaundice.
If the resorption is not complete within 1 month or more, permanent deformation of the skull may occur. Also, in cases where the problem occurs bilaterally, on both sides of the head, more investigations are needed to eliminate the risk of bone fracture in the cranial vault.
The serosanguineous bosa closely resembles the cerebrospinal fluid, being also a swelling (edema) caused by an accumulation of blood in the child's head. This problem also arises after difficult, laborious births, in which the child is subjected to pressures of the mother's bones at the time of birth.
And if the birth is more complicated and the intervention by forceps or vacuum is required, this subcutaneous edema of the skin of the head can occur.
Unlike cephalhematoma, which occurs about 24 hours after birth, serosanguineous bosa is present since birth, but it resolves much faster, even within a few hours or a few days.
Neither this specific condition for newborns requires any particular treatment, because it withdraws itself.
