Techniques and key points for endoscopic cranial base reconstruction/ Carlos Pinheiro-Neto, Maria Peris-Celda.
No full text"Due to close collaboration between otorhinolaryngologists and neurosurgeons, endoscopic endonasal brain surgery has become part of the surgical armamentarium for successful treatment of various cranial base pathologies. Today, it is considered the gold standard surgical technique for many types of skull base tumors. Techniques and Key Points for Endoscopic Cranial Base Reconstruction by pioneering otorhinolaryngologist Carlos D. Pinheiro-Neto and neurosurgeon Maria Peris-Celda, co-editor of Thieme's acclaimed Rhoton's Atlas of Head, Neck, and Brain, encompasses the most important endoscopic cranial base reconstruction techniques performed in the last two decades. The book features contributions from an impressive group of additional experts in this field."--Provided by publisher1 online resourc

No full textTCC (graduação) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Curso de Agronomia.Acreditando que é possível a criação animal de forma ecológica e economicamente sustentáveis, além do crescente aumento do mercado mundial para produtos de origem sustentável e que prezem o respeito ao ambiente e bem-estar animal, realizou-se o Estágio de Conclusão de Curso de Agronomia da Universidade Federal de Santa Catarina acompanhando as atividades diárias de uma fazenda onde o Pastoreio Racional Voisin é utilizado como base no manejo da pastagem e dos animais. A Fazenda Margarida, no estado do Paraná, foi a escolhida para a realização do estágio, uma vez que trabalha com o Pastoreio Racional Voisin em grande escala, além de utilizar este sistema desde 2003, ou seja, os funcionários e o proprietário tem pleno domínio da técnica utilizada. É importante ressaltar que o projeto de Pastoreio Racional Voisin da Fazenda Margarida foi concebido pelos professores Luiz Carlos Pinheiro Machado e Luiz Carlos Pinheiro Machado Filho

Combined endoscopic endonasal transpterygoid and sublabial transmaxillary approaches for a large infratemporal fossa trigeminal schwannoma
No full textBackground Trigeminal schwannomas (TSs) with solitary extracranial location are rare, and surgical excision is challenging. In recent years, the endoscopic endonasal transmaxillary transpterygoid approach (EETPA) has been advocated as an effective strategy for TSs in the infratemporal fossa (ITF). Method We describe the steps of the EETPA combined with the sublabial transmaxillary approach for the surgical excision of a giant mandibular schwannoma of the ITF. Indications, advantages, and approach-specific complications are also discussed. The main surgical steps are shown in an operative video. Conclusion A combined EETPA and sublabial transmaxillary approach represents a safe and effective option for the surgical excision of extracranial TSs

No full textThe endonasal midline inferior intercavernous approach to the cavernous sinus: technical note, cadaveric step-by-step illustration, and case presentation
No full textPurpose Traditional endoscopic endonasal approaches to the cavernous sinus (CS) open the anterior CS wall just medial to the internal carotid artery (ICA), posing risk of vascular injury. This work describes a potentially safer midline cellar entry point for accessing the CS utilizing its connection with the inferior intercavernous sinus (IICS) when anatomically present.Methods The technique for the midline intercavernous dural access is described and depicted with cadaveric dissections and a clinical case.Results An endoscopic endonasal approach exposed the periosteal dural layer of anterior sella and CS. The IICS was opened sharply in midline through its periosteal layer. The feather knife was inserted and advanced laterally within the IICS toward the anterior CS wall, thereby gradually incising the periosteal layer of the IICS. The knife was turned superiorly then inferiorly in a vertical direction to open the anterior CS wall. This provided excellent access to the CS compartments, maintained the meningeal layer of the IICS and the medial CS wall, and avoided an initial dural incision immediately adjacent to the ICA.Conclusion The midline intercavernous dural access to the CS assisted by a 90 degrees dissector-blade is an effective modification to previously described techniques, with potentially lower risk to the ICA
Anatomical Step-by-Step Dissection of Complex Skull Base Approaches for Trainees: Surgical Anatomy of the Endoscopic Endonasal and Endoscopic-Assisted Transmaxillary Transpterygoid Approaches
No full textIntroduction The endoscopic endonasal transpterygoid approach (EETPA) with or without the addition of the endoscopic-assisted sublabial anterior transmaxillary approach (ESTA) has become increasingly utilized for lesions posterior to the pterygopalatine fossa (PPF), including infratemporal fossa (ITF), lateral recess of the sphenoid sinus, Meckel's cave, petrous apex, and parapharyngeal space. The main goal of this study is to develop an educational resource to learn the steps of the EETPA for trainees. Methods EETPA and ESTA were performed in 12 specimens by neurosurgery trainees, under supervision from the senior authors. One EETPA and one ESTA were performed on each specimen on opposite sides. Dissections were supplemented with representative cases. Results After a wide unilateral sphenoidotomy, ethmoidectomy, and partial medial maxillectomy, the anteromedial bone limits of the PPF were identified and drilled out. The pterygoid progress was modularly removed. By enlarging the opening of the posterior and lateral walls of the maxillary sinus through EETPA and ESTA, respectively, the neurovascular and muscular compartments of the PPF and ITF were better identified. The EETPA opens direct corridors to the PPF, medial ITF, middle cranial fossa, cavernous sinus, Meckel's cave, petrous apex, and internal carotid artery. If a more lateral exposure of the ITF is needed, the ESTA is an appropriate addition. Conclusion Despite the steep learning curve of the EETPA, granular knowledge of its surgical anatomy and basic surgical steps are vital for those advancing their learning in complex endoscopic approaches to the ventral skull base when expanding the approach laterally in the coronal plane
