Continuing education Activity

A child"s skull is diluent and more pliable 보다 an adult skull, thus giving less defense to the brain. Head trauma is a common reason of morbidity and mortality in children. That is a continuous presentation in the Paediatric Emergency room (PED) and primary care. Doubt pediatric skull fractures must be evaluated utilizing a CT, plain radiograph, MRI, and also ultrasound to identify the degree of the injury. This activity outlines the evaluation and also management that pediatric skull fractures and also reviews the duty of the interprofessional team in improving care for patients v this condition.

Head trauma can an outcome in a skull fracture and also is a common cause of morbidity and mortality in children. It is a constant presentation in the Paediatric Emergency room (PED) and primary care. Children are more susceptible to head trauma and also skull fracture 보다 adults. A child"s head size is around 18% of the full body surface ar area in infancy.  This will decrease to about 9% through adulthood.  Generally speaking, a child"s skull is diluent and much more pliable, thus offering less protection to the brain.<1><2><3>


Causes the head injury and skull fracture have the right to be separated right into accidental and also non-accidental injuries.  Commonly, head injuries are caused through a fall. Other reasons can incorporate motor vehicle mishaps (MVA), sports-related injuries, or other straight blows to the head. Occasionally, depressed "ping-pong" fractures can take place in newborns because of injury at birth. A non-accidental injury is important for clinicians to identify in youngsters who present with a head injury and also subsequent skull fracture.  This is particularly important in the non-mobile infant. A meta-analysis of 12 studies of skull fractures in abuse has shown a skull fracture to it is in a optimistic predictive worth of 20.1% in doubt or shown abuse cases.<4><5><6>


Head injury is a very common presentation to the PED and also is the many common reason of lethal trauma in children. Fortunately, the majority (80% to 90%) of head injuries can be classified as mild. Very couple of injuries space life-threatening or need neurosurgical intervention. The incidence that skull fracture in kids following head injury ranges from 2% come 20%, and also further epidemiological research is needed for an ext accurate incidence and also prevalence rates. Skull fracture has actually been shown to be much more common in children under the period of 2 years complying with head trauma. A fracture the the calvarium (skull cap) is more common than one at the base of the skull.<7>


The skull deserve to be split into the calvarium and the skull base. The calvarium is made up of the frontal, parietal, occipital, and temporal bones. The skull basic is created of the sphenoid, palatine, and also maxillary bones in addition to portions that the temporal and occipital bones.

Types that Skull Fracture

LinearThis is the many common basic type. The is typically in the temporal or parietal area.

DepressedThis is usually caused by a straight blow to the head and requires a neurosurgical opinion. A depressed skull fracture have the right to sometimes be described as a ping-pong fracture.

OpenAn open fracture dead a high hazard of infection. 

BasalBasal fractures involve any type of of the skeleton of the base of the skull. Basal fractures are more complex due to underlying frameworks such as cranial nerves and sinuses which deserve to lead come hearing loss, facial paralysis, or reduced sense the smell. They also deserve to pose a threat for meningitis.

DiastaticDiastatic fractures happen when there is a separation of the cranial sutures, most typically with the lambdoid suture.

GrowingA cultivation fracture defines herniation that the brain through the broken dura adhering to a skull fracture (often diastatic). It normally presents later and also grows as the mind herniates with the gap, as a persistent ede or pulsatile mass. That is uncommon.

History and also Physical

A concise history can assist the clinician when determining whether a son presenting with a head injury has a high threat of a skull fracture or traumatic brain injury. 

Important determinants include:

Time and also presentation of injury: A delayed presentation should create concern and also further questioning to determine if a non-accidental injury is a possibility.
Mechanism the injury: Fall, dropped,  collision, blow to head, or motor automobile accident (MVA).
Whether the event was witnessed and also if so by whom.
Further details around the injury: In the situation of a fall, keep in mind the height of the fall and landing surface. In the case of one MVA, ask if the patient was ejected indigenous the auto or was rolled over and whether one more passenger to be killed, describe a high-risk injury.
Condition instantly after the injury: period of shed consciousness versus instant cry.
Condition due to the fact that the injury occurred: Level of alertness, eating, vomiting, seizures.
Ear, nose, and throat examination to look for signs of basal skull fracture consisting of haemotympanum, cerebrospinal liquid (CSF) or bloody otorrhoea or rhinorrhoea, fight sign (ecchymosis top top the mastoid process), or raccoon eyes (periorbital ecchymosis). Ring sign can be supplied to assess because that CSF rhinorrhoea/otorrhoea that is combined with blood. As soon as the liquid is dropped ~ above filter paper, the CSF separates together a ring approximately the blood (central blood with a clear ring approximately it). However, ring authorize is not particular to CSF together blood combined with water, saline, and other mucous also will create a ring sign.
Neurological and also cranial nerve check for signs of raised intracranial pressure including fundoscopy. Cranial nerve abnormalities such together visual defect, anosmia, listening defect, facial numbness, or paralysis also can suggest a skull basic fracture.
Head come toe examination assessing for bruising or various other injuries in case of other traumatic injuries, or if suspicious, the non-accidental injury.

As a safeguarding procedure, the clinician constantly needs to carefully consider whether the explained mechanism of injury is continuous with the developmental period of the child and the clinical findings.


 Skull fractures deserve to be established on level radiography, computed tomogram (CT), ultrasound, and magnetic resonance imaging (MRI). Although exercise varies transparent the literature, current guidance uniform the usage of a skull radiograph and also advises the use of a CT scan together the first-line examination of choice if skull fracture is suspected. In a few cases, a well, asymptomatic boy with a localized head injury that is suspicious because that a fracture may be a candidate for a skull x-ray rather of CT. The risks linked with a CT scan in a child also should it is in considered. The younger the child, the greater the threat of malignancy later in life as a result of exposure to ionization radiation. There likewise are linked risks with the sedation or anesthesia that may be required to perform a CT on a child.<8><9>

Multiple clinical decision rules exist to guide clinicians once a child with a head injury requires CT; the PECARN  (Paediatric Emergency Care applied Research Network) head injury algorithm, the CATCH (Canadian Assessment because that Tomography of Childhood Head Injury) rule and also the CHALICE (Children"s Head Injury Algorithm because that prediction the Clinically vital Events) rule. Indications of skull fracture the warrant examination with CT incorporate signs that basal skull fracture, a palpable fracture, a swelling, bruise or hematoma measuring greater than 5 millimeter or apprehension of a depression skull fracture.

Ultrasound can be used to identify skull fractures in younger patient although the is not commonly used and further research studies are essential to evaluate its efficacy. MRI could prove a useful investigation without radiation exposure, but its usage is also limited, early to accessibility in the acute setting.

Repeat CT imaging because that patients v isolated skull fracture is not deemed necessary unless worsening clinical indications develop.

Some centers have safeguarding plans in ar to guide the require for more investigation for non-accidental injury in younger children and also infants with a skull fracture. Routine skeletal surveys in this population with isolated skull fracture might only yield outcomes in the non-mobile infants (less 보다 6 months) unless there are other indications. In these children, a skull radiograph may be forced in enhancement to a CT as it has actually a higher sensitivity for old fractures.

Treatment / Management

Management of skull fractures counts on the place and form of fracture along with the visibility (or absence) the underlying brain injury. Many skull fractures that are basic linear fractures there is no underlying mind injury and also will call for no intervention. Miscellaneous practice fads exist in regard to recommendations for monitoring periods or nearby outpatient followup. There are likewise variations in whether skull fractures have to be treated an in similar way to concussions. In fact, one examine has shown that most fractures requiring treatment do not necessarily require intervention for the fracture alone, yet rather because that an associated underlying injury. Younger patients, and symptomatic patients, should be admitted to the hospital because that an observation period.  Variations to this practice are sustained by multiple research studies that have shown that asymptomatic youngsters with simple fractures have the right to be safely discharged from the emergency department. However, in every of this cases, a CT of the head had been performed to preeminence out an underlying brain injury.

Frontal bone fractures are much more likely to need neurosurgical repair. A depression fracture usually needs intervention. Indications for a neurosurgical elevation of a depressed fracture incorporate depression of 5 millimeters or more, dural injury, underlying hematoma, or gun contamination. An open up fracture will most likely require exploration and washout with antibiotic coverage. Basal skull fractures are usually regulated conservatively unless there is persistent CSF leakage. A patient v a basal skull fracture must not have actually a nasogastric pipe or nasal cannula. Over there is no proof to assistance the role of prophylactic antibiotics in preventing meningitis, although, persistent CSF leak may boost the threat of meningitis.
