What it is
Penetrating traumatic brain injury caused by a projectile entering the cranial cavity. Among the most lethal of all firearm injuries — the majority of victims do not survive to reach hospital. Survivors face severe neurological deficits from direct brain destruction, haemorrhage, oedema, and elevated intracranial pressure. Management is guided by trajectory, Glasgow Coma Scale score, CT findings, and evidence of brainstem function.
Symptoms
Varies with trajectory and location: loss of consciousness, focal motor or sensory deficits, aphasia, visual field loss, seizures, autonomic instability. Intracranial haematoma causes progressive neurological decline. Brainstem involvement causes deep coma, abnormal posturing, and absent brainstem reflexes. Survivors of the acute phase commonly have persistent cognitive, motor, and behavioural deficits requiring long-term rehabilitation.
Approach
Emergency resuscitation, airway management, and urgent CT brain and CT angiography. Surgical decision-making is based on GCS, CT findings, and brainstem function: patients with accessible haematoma causing mass effect or those with purposeful motor activity may benefit from craniotomy and debridement. Prognosis depends heavily on the bullet trajectory — brainstem, bihemispheric, or intraventricular trajectories carry near-certain mortality. Survivors begin structured neurological rehabilitation.
Cranial gunshot wounds
Gunshot wounds to the head are penetrating traumatic brain injuries with a mortality rate exceeding 90% in civilian settings — most victims die before reaching medical care. Among those who survive to hospital, management requires rapid assessment, aggressive resuscitation, and individualised decision-making about neurosurgical intervention.
**Pathophysiology**
A projectile entering the skull causes injury through several mechanisms: - *Direct tissue destruction* along the bullet track - *Cavitation* — the temporary cavity created by the projectile's energy transfer, which is many times larger than the bullet diameter, causing widespread destruction of surrounding brain tissue - *Haemorrhage* — intracerebral haematoma, intraventricular haemorrhage, or subarachnoid haemorrhage - *Cerebral oedema* — diffuse swelling in response to injury that raises intracranial pressure over hours to days - *Infection* — retained bone fragments and foreign material create a nidus for abscess formation
**Emergency assessment and decision-making**
Three factors guide surgical decision-making on presentation: 1. *Level of consciousness* — assessed with the Glasgow Coma Scale (GCS). Patients with GCS 3–5 and no evidence of a treatable haematoma have extremely poor prognoses; aggressive surgical intervention is rarely beneficial 2. *Brainstem neurological function* — pupils, ocular movements, and motor responses. Absent brainstem function indicates irreversible injury 3. *CT findings* — location and extent of haematoma, trajectory of the bullet through the brain, ventricular involvement, and degree of midline shift
**Bullet trajectory and prognosis**
Trajectories through the brainstem, multiple cerebral lobes, or the ventricular system are almost uniformly fatal. Tangential or frontal lobe trajectories in patients with preserved consciousness carry a substantially better prognosis. Many initial survivors develop uncontrolled intracranial hypertension in the days following injury.
**Surgical management**
- *Craniotomy and debridement:* removal of accessible bone fragments, devitalised brain tissue, and the bullet where feasible; evacuation of haematoma causing significant mass effect - *Decompressive craniectomy:* removal of a large bone flap to allow the swollen brain to expand without fatal herniation in selected patients with refractory intracranial hypertension - *ICP monitoring:* intraparenchymal or intraventricular pressure monitors guide intensive care management
**Rehabilitation**
Survivors of cranial gunshot wounds require prolonged, specialised neurorehabilitation addressing motor deficits, aphasia, cognitive impairment, behavioural changes, and epilepsy (which develops in a significant proportion). Neuromodulatory therapies including rTMS and physiotherapy form part of the post-acute rehabilitation programme at Alimran Medical Center.
