Abstract

Background

Interfascial dissection for pterional craniotomy is one of the main techniques to expose the pterional region.

Method

A step-by-step optimized method of interfascial dissection to avoid three main esthetic complications of the pterional approach—upper facial nerve palsy, temporal muscle atrophy, and retro-orbital depression. A video of the interfascial dissection and three artistic drawings are provided in support of this technique.

Conclusion

A safe method of interfascial dissection, respecting anatomy, and avoiding cosmetic complications has been proposed.
