Summary
This study details the anatomy of the frontal branch of the seventh nerve and a technique to preserve it during low frontal approaches. Dissecting under temporal fascia layers ensures safe access for fronto-orbital region surgeries.
Area of Science:
- Neurosurgery
- Anatomy
Background:
- The frontal branch of the seventh nerve is vulnerable during anterior cranial base surgery.
- Low frontal and pterional approaches require careful anatomical consideration for nerve preservation.
Observation:
- Dissection beneath both layers of the temporal fascia provides direct access to the inferior fronto-orbital region.
- This anatomical plane facilitates identification and protection of the frontal branch of the facial nerve.
Findings:
- A specific surgical technique is described for dissecting under the temporal fascia layers.
- This method allows for rapid and safe exposure of the fronto-orbital bony structures.
Implications:
- The described technique aids in preserving the frontal branch of the seventh nerve during specific neurosurgical procedures.
- It is recommended for surgeries involving bony lesions in the fronto-orbital region and osteoplastic pterional craniotomies.
