Transcranial approach
A transcranial approach reaches an encephalocele through the skull, used for many convexity and some anterior types.
In short: Transcranial approach
- It accesses the lesion by opening the skull (a craniotomy).
- It is often used for convexity and complex encephaloceles.
- It allows direct access to the protrusion and membranes.
- It contrasts with the through-the-nose (transnasal) approach.
What it is
It is a surgical approach that reaches an encephalocele through the skull, typically via a craniotomy. It is the "open" alternative to a transnasal (through-the-nose) approach.
Understanding Transcranial approach
It is often used for convexity encephaloceles (such as occipital and parietal types) and for complex anterior encephaloceles, providing direct access to the protrusion, the membranes, and the bony defect. This direct exposure allows the surgeon to manage the sac contents, achieve a watertight closure, and reconstruct the bone. For basal and nasal types, an endoscopic transnasal approach may be used instead; the choice depends on the location and anatomy.
Why it matters
Understanding the transcranial approach helps families see how many encephaloceles are repaired through the skull, and why the approach is chosen based on the lesion's location and complexity.
Common questions
What is a transcranial approach?
Reaching the encephalocele through the skull.
Which encephaloceles is it used for?
Often convexity and complex anterior types.
How does it differ from a transnasal approach?
It goes through the skull rather than the nose.
Bottom line
A transcranial approach repairs an encephalocele through the skull, often used for convexity and complex types.
