Abstract

Abstract:

Objective To explore the anatomical characteristics of the skull base and the petroclival region through the preaurical subtemporal approach. Methods Three fresh and three embalmed adult corpse head were selected and dissected under a portable video microscope. Results Portable video microscope provided a lifelike exposure of the skull base and the petroclival area. The bottom of the temporal lobe epidural detection showed that the rock surface upwarping bow, former inside of chorda tympani, raise the temporal lobe underside, can clearly see the bottom of the cranial fossa, tentorium cerebelli and separation after arachnoid, exposed by the sella turcica structure, can clearly see Labbe vein, the lateral aspect of the brain stem, oculomotor nerve, basal artery and trochlear nerve can be clearly displayed. Conclusion Using portable video microscope via the ear before end of temporal lobe approach can complete microdissection.

Key words: Petroclival region, Preaurical subtemporal approach, Portable video microscopy, Microdissection, Adult
