Summary
Posterior cranial vault distraction osteogenesis effectively increases cranial volume and corrects skull deformities in craniosynostosis. This surgical technique offers a safe and efficient approach for managing complex craniofacial conditions.
Area of Science:
- Neurosurgery
- Pediatric Plastic Surgery
- Craniofacial Surgery
Background:
- Posterior cranial vault distraction is a treatment for intracranial hypertension in craniosynostosis and faciocraniosynostosis.
- It aids in skull harmonization and prevents turricephaly.
- This study details the surgical technique for this procedure.
Purpose of the Study:
- To present the surgical technique of posterior cranial vault distraction osteogenesis.
- To evaluate its effectiveness in managing intracranial hypertension and skull deformities.
Main Methods:
- A circular osteotomy of the posterior skull vault is performed.
- Four distractors are applied to the cranial flap, preserving the dura mater.
- Distraction occurs over approximately one month, aiming for 20mm expansion.
Main Results:
- The technique allows for significant increases in cranial volume.
- Correction of posterior skull deformities is achieved.
- Clinical and radiological signs of intracranial hypertension resolve.
Conclusions:
- Posterior cranial vault distraction osteogenesis is effective in increasing cranial volume and correcting skull shape.
- The procedure is technically straightforward with a low complication rate.
- It represents a primary surgical option for managing faciocraniosynostosis.
