Overview
Plain-Language Overview
Caput Succedaneum is a common condition affecting newborns during delivery. It involves swelling of the soft tissues of the baby's scalp, caused by pressure on the head as it passes through the birth canal. This swelling occurs in the skin and subcutaneous tissue and can cause a noticeable lump on the baby's head. The condition primarily affects the head and scalp, but it does not involve the skull bones. Although the swelling may look concerning, it usually resolves on its own without causing long-term problems. The main health impact is temporary discomfort and visible swelling that disappears within a few days.
Clinical Definition
Caput Succedaneum is defined as a diffuse, edematous swelling of the neonatal scalp that crosses suture lines. It results from extravasation of fluid into the subcutaneous tissues due to pressure exerted on the fetal head during passage through the birth canal, often exacerbated by prolonged or difficult labor. The swelling is superficial, involving the skin and subcutaneous layers, and is typically soft and pitting. It is distinguished from other birth-related scalp injuries by its location and the fact that it crosses suture lines, unlike cephalohematoma. The condition is clinically significant because it can cause transient cosmetic deformity and may be associated with minor bruising but generally does not lead to serious complications or require intervention.
