Abstract:
This report describes the anatomy of the frontal branch of the seventh nerve and a technique for assuring its preservation when doing a low frontal approach. By dissecting under both layers of the temporal fascia, rapid and safe access to the inferior fronto-orbital region may be achieved. This technique is recommended for exposure of a bony lesion in the fronto-orbital region and when performing an osteoplastic pterional craniotomy.
