This book was released on 2024-09-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endoscopic transorbital surgery of the orbit, skull base and brain is a new surgical discipline that has developed over the last decade out of a collaboration between otolaryngologists, neurosurgeons and oculoplastic surgeons. Tumors and other pathology of the skull base are some of the most difficult to approach and treat for surgeons since they lie at the interface of several traditional specialties, namely the eye, the paranasal sinuses and the brain. For this reason, no single surgical specialty is fully trained to independently reach this region, which requires collaborative approaches that are technically demanding and often long and arduous procedures. In the last decade, using the endoscopic techniques and instrumentation, otolaryngologists, oculoplastic surgeons and neurosurgeons, have together shown that the orbit can be used as a minimally disruptive corridor to reach the skull base lateral to the carotid artery as well as other areas that are difficult to access through transcranial or endonasal approaches. These approaches are now even being used to remove brain tumors involving the frontal and temporal lobes, including those that extend through the middle cranial fossa and into the posterior fossa, without visible external scars or the need for a traditional craniotomy. In addition, they have been used to clip aneurysms, treat seizure disorders, drain abscesses, repair CSF (brain fluid) leaks, and restore skull fractures – all without the additional risks, trauma and prolonged recovery of previous open surgical techniques. The literature is now demonstrating that these endoscopic procedures have comparable or improved safety compared to open surgery, while creating less collateral damage, and result in reduced patient stays. Due to their novelty, few surgeons have acquired the necessary experience, knowledge and expertise to introduce these approaches into their practice, yet due to their safety and efficacy they are rapidly becoming a critical skill set. This is the first text of its kind to codify and proliferate these new approaches more rapidly through the country and world, appealing to otolaryngologists, oculoplastic surgeons and neurosurgeons who deal with pathology involving the skull base.

Book excerpt: Unique skull-base surgical resource features strategic, technical, and philosophical pearls from master surgeons In a sense, surgeons go into battle every time they enter the OR. Like soldiers, they must be prepared to make profound sacrifices to protect innocent people (their patients), while putting egos aside and resisting the call of fame. Skull Base Surgery: Strategies by Walter Jean and distinguished contributors provides eloquent expression to the inner voices that speak to surgeons during each stage of battle. Unlike other textbooks that only emphasize the technical building blocks surgeons need, this resource focuses on state-of-the-art skull-base procedures, important thought processes, and vital strategies required to perform them. Size and shape variations, diverse biological characteristics, different anatomic locations and extensions, and specific relationships and entanglements with nerves and vessels make all skull base tumors unique and highly challenging. In addition to anatomy, two other important factors need to be considered every time a surgeon enters the OR – the particular circumstances of the patient and surgeon. Throughout this remarkable book, master neurosurgeons take readers on an insightful journey exploring the decision-making process of choosing and executing a surgical approach, with firsthand pearls from the battlefield. Key Highlights Nine sections organized by anatomy cover tumors in the anterior, anterolateral, lateral, central, postero-superior, and postero-inferior skull base regions, and clivus, petrous bone, and ventricles Thirty-two systematically organized chapters flow from clinical presentation and radiographic/anatomical findings of specific patients and tumors – to decision-making and execution of the surgical approach Real-life cases enhance understanding of all the elements that go into each operation Perspectives sections at the end of each chapter embrace the concept of diverse surgeon viewpoints on similar ideas, techniques, and approaches This exemplary book is essential reading for neurosurgery and otolaryngology residents, fellows, veteran practitioners, and allied health personnel who care for patients with skull base tumors.

Book excerpt: "The combined endoscopic endonasal, transethmoidal, transcribriform approach with endoscope-assisted supraorbital craniotomy is a minimally invasive approach that can be used as an alternative to the classic transcranial, transfacial, or combined craniofacial approaches to lesions of the anterior cranial fossa. This approach is best used for lesions that extend anteriorly to the frontal sinus, laterally beyond the lamina papyracea, and inferiorly into the ethmoid sinus. This chapter details the approach as well as closure of the combined endoscopic endonasal, transethmoidal, transcribriform approach with endoscope-assisted supraorbital craniotomy"--

Download or read book Anterior Skull Base Tumors written by P. Nicolai and published by Karger Medical and Scientific Publishers. This book was released on 2020-07-30 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, interest in the management of anterior skull base tumors has been fostered by the introduction and subsequent rapid expansion of indications of transnasal endoscopic techniques. In parallel, extraordinary progress has been made in all the other disciplines which are involved in the complex process of managing anterior skull base tumors, leading to substantial improvements in diagnosis and treatment. The anterior skull base can be involved in a large variety of tumors of a varying nature and histology, which in the majority of cases originate from adjacent anatomic sites. In fact, primary lesions of the anterior skull base mainly include osteoma and other tumors originating from bone and cartilage. Tumors involving the anterior skull base have their origin prevalently in the sinonasal tract, but lesions developing on the intracranial site, such as meningiomas, may also extend caudally to encroach upon this area. All these lesions are rare, which means that the pertinent literature does not include prospective studies or treatment guidelines based on a high level of evidence. In view of the extreme histological variability of lesions involving the anterior skull base, much emphasis has been placed on addressing the different nuances of treatment in relation to histology, especially for malignant tumors. The chapters focusing on surgery provide divergent views on selection criteria for a specific surgical technique, which is the aim of this publication.
