Chignon (medical term)

Chignon is a term used in the medical field, particularly in obstetrics, to describe a condition related to the presentation of a newborn's head during childbirth. The term originates from the French word for a type of hairstyle, reflecting the appearance of the scalp swelling in affected newborns. This condition is specifically associated with vacuum-assisted deliveries, a common obstetric procedure used to aid the delivery of a baby when complications arise.

Definition[edit | edit source]

A chignon in the medical context refers to the temporary swelling or edema on the scalp of a newborn, which results from the use of a vacuum device during delivery. The vacuum extractor applies suction to the baby's head, aiding in its passage through the birth canal. The pressure from the suction cup leads to localized swelling, or a chignon, which is generally harmless and resolves within a few days after birth.

Indications for Vacuum-Assisted Delivery[edit | edit source]

Vacuum-assisted delivery is indicated in several scenarios during the labor and delivery process, including but not limited to:

Prolonged second stage of labor
Non-reassuring fetal heart rate patterns indicating fetal distress
Maternal exhaustion or inability to effectively push the baby out due to epidural anesthesia
Certain cases of breech presentation where a cesarean section is not preferred or possible

Risks and Complications[edit | edit source]

While vacuum-assisted delivery is a valuable tool in managing certain delivery complications, it is not without risks. The formation of a chignon is one of the most benign side effects. However, more serious complications can occur, including:

Subgaleal hemorrhage, a rare but potentially life-threatening condition involving bleeding into the space between the scalp and skull
Cephalohematoma, a localized blood collection under the scalp
Intracranial hemorrhage, bleeding within the brain, which is extremely rare but serious

Management and Prognosis[edit | edit source]

The chignon itself requires no specific treatment and typically resolves within a few days after birth as the swelling goes down. Parents and caregivers are advised to monitor the newborn for any signs of more serious complications, although these are rare. The prognosis for newborns with a chignon is excellent, with no long-term effects expected from this condition.

Conclusion[edit | edit source]

The use of vacuum-assisted delivery and the resulting chignon is a testament to the advancements in obstetric care, allowing healthcare providers to safely manage difficult deliveries. While the appearance of a chignon may be concerning to new parents, it is important to understand that it is a temporary condition with no lasting impact on the child's health.
