|Form of presentation||Poster|
Introduction: The combined anterior transpetrosal and subtemporal/transcavernous approach to the petroclival junction is a demanding technique, which provides a wide exposure of the area. In this manuscript we provide technical instructions with anatomical consideration of important landmarks and a literature review of the clinical applications for this approach.
Methods: The combined approach was performed in two cadaveric specimen and relevant anatomical aspects were studied. Additionally, the authors performed a review of the literature focusing on indications, neurologic outcome and complications associated with the technique.
Results: A combined anterior transpetrosal and subtemporal/transcavernous approach offers a wide exposure of the crus cerebrum, pons, basal temporal lobe, cranial nerves III to VII/VIII, PCA, SCA, BA, AICA and PComA. It has been successfully applied with acceptable morbidity and mortality rates, mainly for petroclival menigiomas.
Conclusion: The combined approach studied is a useful skull base approach to the petroclival junction and can be applied to treat large or complex pathologies such as spheno- petroclival meingiomas, chordomas or chondrosarcomas. Detailed anatomical knowledge is essential.
