Anterior Skull Base Tumors

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.

The consummate guide on the contemporary management of complex skull base tumors from renowned multidisciplinary experts! An increased understanding of the biology and molecular characterization of skull base tumors has led to innovative new approaches. Endoscopic tumor resection, surgical reconstruction, and advances in radiation delivery, chemotherapy, and targeted biologic therapy, have greatly expanded treatment options for patients with these challenging tumors. The updated second edition of Comprehensive Management of Skull Base Tumors by master surgeons Ehab Hanna, Franco DeMonte, and an impressive group of global experts reflects expanded knowledge of skull base tumors and evidence-based advances. This generously illustrated second edition is organized into three sections with 42 chapters. Section I features expanded coverage of endonasal skull base anatomy and surgical principles, as well as radiotherapeutic advances such as proton therapy and stereotactic radiation. Section II is focused on site-specific procedures with emphasis on surgical approaches, and Section III focuses on tumor-specific considerations with emphasis on multidisciplinary treatment approaches. Core topics of this thorough book include pathology, genetics, diagnostic considerations, surgical reconstruction, rehabilitation, chemotherapy, functional outcomes, quality of life issues, neurocognitive assessment, and cerebrovascular management. Key Features In-depth discussion of anatomic regions of the cranial base, including surgical anatomy, regional pathology, differential diagnosis, clinical assessment, diagnostic imaging, and surgical approaches Incidence, epidemiology, pathology, staging, multidisciplinary treatment, outcome, and prognosis for a wide range of neoplasms including squamous cell carcinoma, chondrosarcomas, chordomas, meningiomas, schwannomas, paragangliomas, pituitary adenomas, craniopharyngiomas, epidermoids, and fibro-osseous lesions Outstanding illustrations, surgical and clinical photos, imaging, tables, and videos new to this edition, enhance understanding of complex skull base tumors The most comprehensive resource available today on the management and treatment of skull base tumors, this book is essential reading for neurosurgical and otolaryngology residents. It will also benefit surgeons who specialize in oromaxillofacial, craniofacial, and plastic and reconstructive surgery.

The management of tumors in and adjacent to the skullbase is challenging given the complex and critically important anatomy of the region and the wide diversity of tumor pathologies that may be encountered. To help navigate the complexities of contemporary multidisciplinary management of these patients, Drs. Hanna and DeMonte bring you Comprehensiv

Skull base anatomy is extremely complex, with vital neurovascular structures passing through multiple channels and foramina. Brain tumors such as pituitary tumors, acoustic neuromas, and meningiomas are challenging to treat due to their close proximity to cranial nerves and blood vessels in the brain, neck, and spinal cord. Medical imaging is an essential tool for identifying lesions and critical adjacent structures. Detecting and precisely mapping out the extent of disease is imperative for appropriate and optimal treatment planning and ultimately patient outcome. Eugene Yu and Reza Forghani have produced an exceptional, imaging-focused guide on various neoplastic diseases affecting the skull base, with contributions from a Who's Who of prominent radiologists, head and neck surgeons, neurosurgeons, and radiation oncologists. The content is presented in a clear and concise fashion with chapters organized anatomically. From the Anterior Cranial Fossa, Nasal Cavity, and Paranasal Sinuses - to the Petroclival and Lateral Skull Base, an overview and detailed analysis is provided for each region. Key Highlights Fundamentals of skull base imaging, including recent developments in diagnostic modalities More than 400 radiographs, color anatomical drawings, and color intraoperative photos elucidate the imaging appearances of a wide spectrum of disease affecting the skull base, as well as important anatomic variants and pathways of disease spread Clinically oriented imaging approach focuses on diagnostic and prognostic features important in the evaluation of skull base abnormalities Atlas of skull base CT and MRI anatomy provides an easy to access, quick reference for identifying important anatomic landmarks Insights on the pathways of tumor growth and the role of clinical imaging in the management of skull base cancers Critical and contrasting viewpoints from multidisciplinary experts provide a well-rounded perspective This invaluable resource chronicles current knowledge in state-of-the-art skull base tumor imaging with clinical pearls on pathophysiology, prognosis, and treatment options. It is a must-have for radiology, neurosurgery, and otolaryngology residents and clinicians who care for patients with head and neck neoplasms.

This book is a comprehensive guide to skull base imaging. Skull base is often a “no man’s land” that requires treatment using a team approach between neurosurgeons, head and neck surgeons, vascular interventionalists, radiotherapists, chemotherapists, and other professionals. Imaging of the skull base can be challenging because of its intricate anatomy and the broad breadth of presenting pathology. Although considerably complex, the anatomy is comparatively constant, while presenting pathologic entities may be encountered at myriad stages. Many of the pathologic processes that involve the skull base are rare, causing the average clinician to require help with their diagnosis and treatment. But, before any treatment can begin, these patients must come to imaging and receive the best test to establish the correct diagnosis and make important decisions regarding management and treatment. This book provides a guide to neuoradiologists performing that imaging and as a reference for related physicians and surgeons. The book is divided into nine sections: Pituitary Region, Cerebellopontine Angle, Anterior Cranial Fossa, Middle Cranial Fossa, Craniovertebral Junction, Posterior Cranial Fossa, Inflammatory, Sarcomas, and Anatomy. Within each section, either common findings in those skull areas or different types of sarcomas or inflammatory conditions and their imaging are detailed. The anatomy section gives examples of normal anatomy from which to compare findings against. All current imaging techniques are covered, including: CT, MRI, US, angiography, CT cisternography, nuclear medicine and plain film radiography. Each chapter additionally includes key points, classic clues, incidence, differential diagnosis, recommended treatment, and prognosis. Skull Base Imaging provides a clear and concise reference for all physicians who encounter patients with these complex and relatively rare maladies.
