Stepwise dissection using the extradural transcavernous approach (Dolenc's approach) via a modified orbitozygomatic craniotomy

Background: To present a stepwise dissection using the extradural transcavernous approach (Dolenc's approach). Methods: Two formalin-fixed and latex-injected imported cadaver heads were dissected at the Tri-Service General Hospital skull base laboratory. Extradural transcavernous dissections were made via a modified orbitozygomatic craniotomy. Results: The results were illustrated with a series of photographs of the scalp phase, skull phase, and dura phase sequences. Conclusions: Stepwise dissection using skull base approaches can be performed in a systematic manner so that workshop participants can efficiently learn more about the donated human cadaver.
