13. Microsurgical training model with nonliving swine head. Alternative for neurosurgical education
PURPOSE: This paper proposes a practical model of microneurosurgical training using a nonliving swine head. METHODS: Fresh porcine heads were obtained from butchery and dissected at our Laboratory of Microsurgery. Brain and skull base surgery were trained under microscopic magnification. RESULTS: Several neurosurgical procedures could be simulated in the no

15. Panorama of Reconstruction of Skull Base Defects: From Traditional Open to Endonasal Endoscopic Approaches, from Free Grafts to Microvascular Flaps
Introduction A substantial body of literature has been devoted to the distinct characteristics and surgical options to repair the skull base. However, the skull base is an anatomically challenging location that requires a three-dimensional reconstruction approach. Furthermore, advances in endoscopic skull base surgery encompass a wide range of surgical path

16. Advances in Computed Tomography Evaluation of Skull Base Diseases
Introduction Computed tomography (CT) is a key component in the evaluation of skull base diseases. With its ability to clearly delineate the osseous anatomy, CT can provide not only important tips to diagnosis but also key information for surgical planning. Objectives The purpose of this article is to describe some of the main CT imaging features that c

17. Management of Carotid Artery Injury in Endonasal Surgery
Introduction Carotid artery injury (CAI) is the most feared and potentially catastrophic intraoperative complication an endoscopic skull base surgeon may face. With the advancement of transnasal endoscopic surgery and the willingness to tackle more diverse pathology, evidence-based management of this life-threatening complication is paramount for patient s

19. Nuances in the Treatment of Malignant Tumors of the Clival and Petroclival Region
Introduction Malignancies of the clivus and petroclival region are mainly chordomas and chondrosarcomas. Although a spectrum of malignancies may present in this area, a finite group of commonly encountered malignant pathologies will be the focus of this review, as they are recognized to be formidable pathologies due to adjacent critical neurovascular struc

20. Evolution of Minimally Invasive Approaches to the Sella and Parasellar Region
Introduction Given advancements in endoscopic image quality, instrumentation, surgical navigation, skull base closure techniques, and anatomical understanding, the endonasal endoscopic approach has rapidly evolved into a widely utilized technique for removal of sellar and parasellar tumors. Although pituitary adenomas and Rathke cleft cysts constitute the

21. Histomorphometric analysis of the temporal bone after change of direction of force vector of mandible: an experimental study in rabbits
OBJECTIVES: The present study aimed at performing a histological evaluation of the response of temporal bone tissue to a change of direction of the force vector of the mandible in relation to the base of the skull. MATERIAL AND METHODS: Adult rabbits were assigned into four groups with two control and four experimental animals in each group. experimental ani

22. Early cephalometric characteristics in Class III malocclusion
OBJECTIVE: Early identification of craniofacial morphological characteristics allows orthopedic segmented interventions to attenuate dentoskeletal discrepancies, which may be partially disguised by natural dental compensation. To investigate the morphological characteristics of Brazilian children with Class III malocclusion, in stages I and II of cervical ve

23. Estudo do retalho nasosseptal para reconstrução endoscópica da base do crânio anterior / Study of the nasosseptal flap for endoscopic skull base reconstruction of the anterior cranial base
Introdução: O uso do retalho nasosseptal (NS) para a reconstrução endoscópica da base do crânio foi fator fundamental para o avanço dos acessos endonasais expandidos. Objetivos: Aferir as dimensões do retalho NS e do defeito da base do crânio anterior (BCA) após ressecção craniofacial endoscópica e verificar a suficiência do retalho para cobrir

24. Estudo da anatomia endoscópica do acesso transpterigóideo e da artéria carótida interna por via endonasal / Anatomical study of the endoscopic endonasal transpterygoid approach and the internal carotid artery
INTRODUÇÃO. Durante a última década, os avanços tecnológicos, o maior domínio da anatomia e das técnicas operatórias e de reconstrução da base do crânio por via endonasal propiciaram a expansão da cirurgia endoscópica para além dos limites da sela túrcica. O acesso transpterigóideo é uma etapa comum ao acesso as fossas cranianas média e po
