Head Injuries- most common cause of traumatic death in children
Main Causes:- Falls- Motor vehicular crashes- Pedestrian accidents- Bicycle injuries- Other injuries
![Page 44: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/44.jpg)
Pathophysiology
• Brain swelling
• Increase mass effect
• Increase Intracranial Pressure
• Compromised brain perfussion
• Herniation of brain tissue across the tentorium, falx or through the foramen magnum causing significant morbidity and often death
![Page 45: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/45.jpg)
Moderate to Severe Head Injuries-- usually present in obtunded or combative state-- Late clinical Findings:
unequal and non reactive pupilsfocal neurologic findingsabnormal posturing
![Page 46: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/46.jpg)
In-hospital resuscitation and evaluation of moderate head injuries
• Rapid, systematic manner with diagnostic and therapeutic maneuvers proceeding simultaneously
• ABC’s of Trauma (airway, ventilation, preventing hypoxia and hypotension)
![Page 47: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/47.jpg)
Initial neurologic evaluation and management
• In moderately injured, examination is abbreviated and should focus on– Level of consciousness– Pupillary light reflex– Extraocular eye movement– Motor examination
• Head should be palpated
• Signs of basal skull fracture(otorrhea)
![Page 48: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/48.jpg)
• Triad suggestive of transtentorial herniation– Deteriorating level of consciousness– Pupillary dilatation– Hemiparesis
• Neurological exam: unreliable in accurately predicting intracranial pathology, tomography is usually indicated
![Page 49: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/49.jpg)
Criteria for CT scanning following craniocerebral trauma
• GCS 14 or less
• GCS 15 with the following– Documented loss of consciousness– Focal neurologic deficit– Signs of basal skull fracture
![Page 50: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/50.jpg)
Skull radiography and angiography
• In the absence of CT scan, skull radiographs are helpful
• Fractures are seen on– Epidural hematoma 66-100%– Subdural 18-60%– Intracerebral 40-80%
• Presence of skull fracture, although suggestive of hematoma is not a reliable indicator of the type of intracranial injury
![Page 51: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/51.jpg)
• In rapidly deteriorating or comatose patient, cerebral angiography or exploratory burr holes is indicated
![Page 52: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/52.jpg)
Early repeat CT: when indicated?
• When hemorrhagic but nonsurgical lesion in initial CT, a repeat within 4 – 8hrs should be done
• 60% with initial nonoperative lesion on initial CT required surgical intervention after the repeat

Interpreting Neurological findings
• Ipsilateral pupil dilatation - expanding hematoma causing transtentorial temporal herniation and oculomotor nerve impingement
• Moderate anisocoria and sluggish pupil – impending uncal herniation

Surgical management of acute traumatic intracranial hematomas
• Subdural or epidural hematoma – 5mm thick– Midline shift– GCS<8

Exploratory Burr holes
• First burr hole-temporal region, above the zygomatic arch according to neurological findings– Ipsilateral to the dilated pupil– Contralateral to the abnormal motor response– Ipsilateral to the skull fracture

Medical management of Intracranial hypertension
• Preemptive measures– Head elevation to 30 degrees– Mild hyperventilation (PaCO2 30-35mmHg)– Maintenance of euvolemia– Maintenance of CPP 70mmhg or higher– Maintenance of normothermia (<37.5) – Seizure prophylaxis

• Primary therapy– Ventricular cerebrospinal fluid drainage– Sedation– Neuromuscular blockage
• Secondary therapy– Bolus mannitol
• Tertiary therapy– Metabolic suppressive therapy with
barbiturates or profopol

- subdural and extradural hematoma
- Growing skull fracture

Discussion
Traumatic Intracerebral Hematomas & Contusion
--can occur in any region of the brain
--most commoly in subfrontal & anterior temporal regions at the base of the brain
--due to the impact of the brain on the rough surface of the skull base
--these may start as small lesions but may progressively enlarge
![Page 60: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/60.jpg)
Discussion
Epidural Hematoma
--blood collects between the dura and inner table of the skull
--associated with arterial bleeding from the middle meningeal artery
--associated with lucid intervals, or period of unconsciousness
-- CT: Lenticular shape( football shape) hyperdense( white) he along the skull table
![Page 61: Case Presentation and Discussion on Craniofacial Injury Jeffy G. Guerra, MD Level III Surgery Resident Department of Surgery Ospital ng Maynila Medical](https://reader035.vdocuments.mx/reader035/viewer/2022062801/56649e7b5503460f94b7ca0b/html5/thumbnails/61.jpg)
DiscussionSubdural Hematoma
--most common traumatic mass lesion
--20-40% of severely head injured px
--potential space between dura & arachnoidal meningeal layers
--ascribed to tearing of small veins that bridges the spaces between
cerebral cortex and overlying dura
-- CT: crescent shaped hyperdense hge
