Fractures of the skull require immediate attention to prevent further damage. A Gigli wire saw is used in conjunction with a small trephine to create openings in the skull, allowing access to remove blood clots or relieve pressure on the brain. The bone flap created should be carefully managed to avoid inward displacement. After creating the osteoplastic flap and turning it back, any clot must be removed gently while securing bleeding arteries. Subdural clots may necessitate further dura opening for proper treatment. In cases of increased intracranial tension, a section of fascia lata can be used to replace damaged dura mater. Lumbar puncture can aid in closing the scalp and skull when necessary. The prognosis varies widely depending on the extent of cranial damage and risk factors such as infection or meningitis.

Prognosis is influenced by the severity of trauma, symptoms, and potential for complications like traumatic epilepsy or chronic headaches. Late sequelae may develop months after recovery from initial injury.
<Callout type="risk" title="Potential Risks">Fractures involving the posterior fossa carry a higher mortality rate due to difficulty in draining blood.</Callout>
Late symptoms such as tumor, gumma, or abscess formation can occur years post-injury and may require ongoing medical management.
Key Takeaways
- Use a Gigli wire saw and small trephine to create openings in the skull for treating fractures.
- Secure bleeding arteries and remove clots gently to prevent further damage.
- Consider fascia lata transplantation if increased intracranial tension prevents dural closure.
Practical Tips
- Use DeVilbiss forceps instead of a saw to connect trephine openings for cleaner cuts.
- Perform lumbar puncture during skull surgery to facilitate scalp and skull closure in difficult cases.
Warnings & Risks
- Avoid using chisel and mallet due to the shock they produce, which can worsen injury.
- Be cautious of potential late sequelae such as epilepsy or chronic headaches following head injuries.
Modern Application
While modern neurosurgical techniques have advanced significantly since 1915, understanding historical methods like trephining is crucial for emergency situations where specialized equipment may not be available. Knowledge of these procedures can save lives in remote areas or during disasters.
Frequently Asked Questions
Q: What tools are recommended for creating an osteoplastic flap?
A small trephine and a Gigli wire saw, along with DeVilbiss cutting forceps, are recommended to create the necessary openings in the skull.
Q: Why is it important to secure bleeding arteries during surgery for skull fractures?
Securing bleeding arteries prevents further hemorrhage and reduces the risk of complications such as meningitis or traumatic epilepsy.
Q: What are some late symptoms that can develop after a head injury?
Late symptoms may include tumor, gumma, abscess formation, chronic headaches, vertigo, and epileptic convulsions months to years post-injury.
