Repair of lateral temporo-sphenoidal encephalocoele via an endoscopic transorbital approach: ex vivo 3D printed simulation followed by in vivo deployment.

We have shown that the transorbital approach provides adequate surgical access. In our single case, surgical repair of a lateral temporo-sphenoidal encephalocoele via TOA was feasible, safe, and effective. This approach may offer some advantages compared with transcranial or endonasal approaches.
