Overview
An open wound of the head refers to any traumatic injury that breaks the continuity of the scalp, exposing underlying tissues such as blood vessels, subcutaneous fat, muscle, or even bone. These injuries can range from minor superficial cuts to severe lacerations that penetrate deep into the skull structure.
The scalp is highly vascular, meaning it has an abundant blood supply, which makes head wounds prone to significant bleeding even when the injury appears minor. This rich blood supply also means that scalp wounds generally heal well when properly treated, but they require immediate and appropriate medical attention to prevent complications.
Open head wounds can be particularly concerning because they may be associated with underlying brain injury, skull fractures, or other serious complications. The severity of the wound doesn't always correlate with the extent of internal damage, making professional medical evaluation essential for all significant head injuries.
These injuries are common in emergency departments, accounting for a significant portion of trauma cases. They can occur in people of all ages but are particularly frequent in children due to their active lifestyles and in elderly individuals due to increased fall risk.
Symptoms
The symptoms of an open head wound can vary significantly depending on the depth, location, and severity of the injury. Some symptoms may appear immediately, while others may develop over time.
Immediate Symptoms
- Active bleeding: Often profuse due to the scalp's rich blood supply
- Headache: May be mild to severe, often localized to the injury site
- Pain and tenderness: Sharp or throbbing pain at the wound site
- Visible wound: Open cut, laceration, or tear in the scalp
- Swelling: Tissue swelling around the injury site
Neurological Symptoms
- Dizziness: Feeling unsteady or lightheaded
- Nausea and vomiting: May indicate increased intracranial pressure
- Confusion: Disorientation or difficulty concentrating
- Loss of consciousness: Brief or prolonged unconsciousness
- Memory problems: Difficulty remembering events before or after the injury
Signs of Serious Injury
- Clear fluid drainage: Cerebrospinal fluid leaking from the wound
- Visible bone or brain tissue: Indicating a penetrating injury
- Seizures: New onset seizures following head trauma

Lifestyle and Environmental Factors
- Alcohol use: Impaired judgment and coordination
- Unsafe environments: Poor lighting, slippery surfaces, or hazardous conditions
- Lack of protective equipment: Not wearing helmets during high-risk activities
- Aggressive behavior: Involvement in fights or violent situations
Diagnosis
Proper diagnosis of an open head wound involves a systematic evaluation to assess the extent of injury and identify any associated complications.
Initial Assessment
- Primary survey: Assessment of airway, breathing, and circulation
- Glasgow Coma Scale: Evaluation of consciousness level
- Vital signs monitoring: Blood pressure, heart rate, and respiratory status
- Neurological examination: Assessment of motor and sensory function
Physical Examination
- Wound inspection: Assessment of size, depth, and location
- Scalp examination: Palpation for skull fractures or foreign objects
- Cranial nerve testing: Evaluation of nerve function
- Cervical spine assessment: Ruling out neck injuries
Imaging Studies
- CT scan of the head: To identify skull fractures, bleeding, or brain injury
- X-rays: To detect foreign objects or bone fragments
- MRI: For detailed soft tissue evaluation when indicated
- Cervical spine imaging: If neck injury is suspected
Laboratory Tests
- Complete blood count: To assess blood loss and infection
- Coagulation studies: To evaluate bleeding risk
- Blood type and crossmatch: In case transfusion is needed
- Toxicology screen: If substance use is suspected
Specialized Assessments
- Neurosurgical consultation: For complex or penetrating injuries
- Ophthalmologic examination: If vision changes are present
- Psychiatric evaluation: If injury was self-inflicted
Treatment Options
Treatment of open head wounds depends on the severity, location, and associated injuries. The primary goals are to control bleeding, prevent infection, and address any underlying brain injury.
Emergency Treatment
- Bleeding control: Direct pressure, elevation, and pressure points
- Airway management: Ensuring adequate breathing and oxygenation
- IV access: For fluid resuscitation and medication administration
- Pain management: Appropriate analgesics while monitoring neurological status
- Tetanus prophylaxis: Vaccination if immunization is not current
Wound Care
- Wound irrigation: Thorough cleaning with sterile saline
- Debridement: Removal of foreign material and devitalized tissue
- Hemostasis: Control of bleeding using various techniques
- Closure methods: Sutures, staples, or tissue adhesives
- Dressing application: Sterile wound covering and protection
Surgical Interventions
- Primary closure: Direct suturing of the wound edges
- Scalp flap reconstruction: For large defects requiring tissue rearrangement
- Craniotomy: If underlying brain injury requires surgical intervention
