The hair loss develops as a result of tissue necrosis from prolonged pressure against the ring of the cervical os during the birthing process.
In most cases, hair grows back over time, but scarring and hair loss are sometimes permanent. Tanzi and colleagues believe that this condition is common, but that it is underrecognized and therefore underreported in the pediatric literature. A fi rm, enlarged unilateral or bilateral bump covering one or more bones of the scalp characterizes the lesion.
The mass cannot be transilluminated. Cranial sutures clearly defi ne the boundaries of the cephalohematoma, although a caput succedaneum or scalp swelling overlying the cephalohematoma can obscure those boundaries. The parietal bones are the most common site of injury, but a cephalohematoma can occur over any of the skull bones.
The right parietal bone is involved twice as often as the left, with unilateral five times as likely as bilateral parietal bone involvement. The infant may be sensitive to palpation of the cephalohematoma, especially in the case of an underlying skull fracture.
Cephalohematoma occurs twice as often in males as in females, for unknown reasons.

It is more common in primagravidas, in large infants, following instrument-assisted deliveries with vacuum or forceps , following prolonged difficult labor, when cephalopelvic disproportion exists, when the head is in a deviant position occipital posterior, occipital transverse , or when a scalp electrode has been placed. Cephalohematoma is an injury that results from trauma to the skull as it is forcefully and repeatedly compressed against the pelvic bones with contractions during labor.
This shearing action causes bleeding of the emissary and diploic veins into the subperiostial layer of the skull figure 2. The bleeding slowly lifts the periosteum away from the skull and is contained by the ligaments that attach the periosteum to the skull at the cranial suture lines. Cephalohematoma occurs in a deeper, more vascular portion of the scalp than caput succedaneum, which accounts for the increased blood content of a cephalohematoma, as depicted in figure 2.
Although most cephalohematomas occur secondary to trauma, they have been diagnosed in utero by prenatal ultrasound and have been reported in neonates born via cesarean section without labor. Linear skull fractures occur in about 5 percent of unilateral8,10 and about 18 percent of bilateral cephalohematomas. Routine x-rays are not recommended, but should be obtained when the cephalohematoma is excessively large, when central nervous system symptoms are present, or when an extremely difficult delivery has taken place.
On rare occasions, a cephalohematoma persists beyond four weeks and begins to calcify. Petersen and colleagues report on two cases of cephalohematomas in infants that calcified and caused misshapen heads.
Although rare, calcified or ossified cephalohematomas may cause significant deformities of the skull requiring treatment. If an infant presents with signs and symptoms of sepsis and the focus of sepsis cannot be explained, the cephalohematoma should be suspected as the primary source of infection.
The shearing of emissary and diploic veins during labor is responsible for the increased blood content of the cephalohematoma. From: Netter, F.

The system used for vacuum delivery in our hospital is the Kiwi Omnicup. The inclusion criteria were term delivery 37—42 weeks , singleton pregnancy, cephalic presentation, and second stage of vaginal delivery.
The exclusion criteria were foetal or neonatal anomalies such as foetal growth problems, congenital heart diseases, surgical diseases and cases involving two modes of assisted delivery i. We did not include cases in which data for one or more variables were not available in the records.
For controls, we selected the forceps-assisted delivery and the spontaneous vaginal delivery managed by the same team immediately preceding each vacuum delivery. We analysed the following maternal characteristics: age, parity and maternal disease maternal hypertension, gestational diabetes and preeclampsia. The neonatal characteristics under study were gestational age, sex and birth weight.
We considered the following minor neonatal complications: soft tissue trauma, cephalohaematoma, jaundice, hyperbilirubinaemia treated with intensive phototherapy and transitory brachial plexus injury. The major complications under study were hypoxic-ischaemic encephalopathy HIE , intracranial or subgaleal haemorrhage, skull fracture, seizures and permanent brachial plexus injury.
We collected maternal data from antenatal and obstetric electronic records, including maternal demographic characteristics, parity, complications or diseases during pregnancy, and delivery characteristics.
We obtained data for neonatal variables, such as gestational age, sex, birth weight and the Apgar score, from the hospital birth records.
We defined brachial plexus injury as a flaccid paralysis of an arm at birth, with the passive range of motion being greater than the active range of motion. The diagnosis of neonatal intracranial haemorrhage was based on brain imaging by the transfontanelar ultrasound technique. Hypoxic-ischaemic encephalopathy in a newborn was defined as a 5-min Apgar score of less than 5 and evidence of metabolic acidosis associated with one or more of the following signs of neurologic dysfunction: depression of the level of consciousness, respiratory depression, abnormality of muscle tone, disturbances of cranial nerve function and seizures in the first week of life.
Our NICU admits neonates for intensive and intermediate care. We analysed the data with the software SPSS version We fitted multivariable logistic regression models including variables that exhibited significant differences between groups in the univariable analysis.

We defined statistical significance as a P-value of less than. Since the study consisted in the analysis of anonymized hospital population data, it was deemed exempt from the need to obtain approval from the Hospital Ethics Committee.The right parietal bone is involved twice as often as the left, with unilateral five times as likely as bilateral parietal bone involvement.
