Book excerpt: Introduction : La base du crâne centrale sépare le compartiment intracrânien et les espaces extracrâniens rhinopharyngés et sinusiens. Les pathologies de cette région sont variées et peuvent se développer à partir des éléments intracrâniens, extracrâniens ou de la base du crâne elle-même. Elles sont rares, surtout chez l'enfant. La voie cranio-faciale a été la voie d'abord chirurgicale de référence avant le développement de la voie endoscopique endonasale. L'objectif de cette thèse était de déterminer les spécificités diagnostiques et thérapeutiques chirurgicales des diverses pathologies de la base du crâne centrale de l'enfant, pour l'Oto-Rhino-Laryngologiste. Matériels et méthodes : Il s'agit d'une étude rétrospective de dossiers de patients opérés par l'ORL éventuellement en association avec le Neurochirurgien à l'Hôpital Pédiatrique de la Timone, entre 1995 et 2017. Les patients ayant eu une lésion de la base du crâne centrale traitée chirurgicalement ont été inclus. Résultats : Nous avons inclus 51 patients. L'âge moyen était de 10 ans au moment de la chirurgie (de 19 jours de vie à 19 ans). Dix-sept patients avaient une pathologie tumorale. Les signes cliniques variaient en fonction de la localisation tumorale (signes rhinologiques, ophtalmologiques, détresse respiratoire). Les fibromes nasopharyngiens étaient réséqués par voie endoscopique endonasale 24 heures après une artérioembolisation. Les lésions intrasellaires étaient aussi abordées par voie endoscopique endonasale. Les lésions intrinsèques de la base du crâne (fibrome ossifiant) ou ayant un contingent intracrânien important avaient nécessité un abord transcrânien ou un abord combiné. Treize patients avaient une déhiscence de la base du crâne. Celles-ci peuvent se manifester par une rhinorrhée claire chronique, une obstruction nasale (méningocèle/méningoencéphalocèle) ou des épisodes de méningite. Pour les kystes et/ou fistules du dos du nez, une communication avec le compartiment intracrânien est à rechercher avec un scanner et une IRM ; un abord transcrânien est à prévoir si une telle communication est suspectée. Les brèches sont réparées par voie endoscopique endonasale. Un abord combiné transcrânien et endonasal ou endonasal seul peuvent être choisis pour les méningocèles/méningoencéphalocèles. Parmi les 21 patients qui avaient une pathologie infectieuse, 19 avaient une complication intracrânienne de sinusite aiguë (empyème extra ou sous-dural, abcès cérébral, thrombophlébite cérébrale). Un drainage par voie transcrânienne était effectué en cas de collection volumineuse, de déficit neurologique, d'hypertension intracrânienne ou d'échec d'un drainage sinusien ou d'une antibiothérapie seule. Conclusion : Les signes cliniques des pathologies de la base du crâne sont variés mais certains sont spécifiques à une catégorie d'affections. L'abord endoscopique endonasal permet une prise en charge chirurgicale efficace des pathologies de la base du crâne centrale, même chez les nourrissons. Cependant, elle ne remplace pas l'abord transcrânien, notamment pour les extensions tumorales intracrâniennes importantes, pour certaines méningocèles et méningoencéphalocèles, pour les empyèmes ou abcès cérébraux volumineux.
Download or read book Imagerie Haute R solution en pathologie de l oreille et de la base du cr ne written by Frédérique Dubrulle and published by . This book was released on 2010 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Depuis le début des années 1990, l'imagerie de l'oreille et de la base du crâne s'est considérablement développée. Des pathologies récentes, mal connues ont été explorées en imagerie, en particulier en IRM. L'objectif de mes travaux de recherche, a été de développer des séquences Haute Résolution (HR) sur l'oreille et la base du crâne permettant une analyse sémiologique fine et une caractérisation de ces différentes pathologies dans l’objectif d’une prise en charge plus adaptée. Le début de mes travaux a été orienté vers le conduit auditif interne. Mon but initial a été de mettre point et de développer une séquence 3 HR T2 sur l'oreille interne et le conduit auditif interne ainsi qu’une séquence spin écho T1 HR en coupes fines. Ces séquences ont permis l’analyse précise de l'extension des schwannomes vestibulaires dans le fond du conduit auditif interne. Cette étude a permis de dégager des critères intéressants en imagerie dans le choix thérapeutique (chirurgie versus radio-chirurgie) et dans le choix de la voie d'abord chirurgicale. Mon travail s’est également orienté vers le développement des séquences de diffusion en base du crâne, le but était de développer une séquence de diffusion HR dans le suivi des cholestéatomes opérés de l'oreille moyenne. Les récidives de cholestéatome sont fréquentes et les oreilles opérées sont parfois difficiles à analyser en TDM en cas de comblement de la cavité opératoire. Des séquences IRM spécifiques sont alors nécessaires pour différencier une récidive de cholestéatome, du tissu fibro-inflammatoire fréquemment présent. Plusieurs auteurs avaient montré l'intérêt des séquences de diffusion du fait de coefficients de diffusion très différents entre le tissu fibro-inflammatoire et le cholestéatome. Cependant ces premières séquences de diffusion EPI basse résolution, étaient peu adaptées au rocher et la base du crâne. Notre travail a été de mettre au point et de développer une séquence de diffusion HR Turbo Spin écho adaptée à l'oreille et à la base du crâne permettant le dépistage des récidives de cholestéatome et de valider cette séquence par comparaison au gadolinium tardif et à la chirurgie. Mon travail sur la base du crâne haute résolution m'a également permis de développer des séquences Spin Echo T1 et 3D Echo de gradient T1 en Haute Résolution avec saturation de la graisse permettant une analyse fine des extensions tumorales périnerveuses à la base du crâne principalement dans les cancers du nasopharynx. Ces travaux ont permis de définir les voies d'extension précises de ces tumeurs afin de ne pas sous-évaluer le stade initial de ces tumeurs dans la classification TNM de l'UICC. Ces travaux associés à ceux d'autres chercheurs ont permis de mettre à jour récemment cette classification UICC des tumeurs du nasopharynx. Une de mes principales voies de recherche a été le dépistage, l'analyse et la description des pathologies de l’oreille interne. Une étude longitudinale menée de 1998 à 2008 incluant toutes les pathologies intra-labyrinthiques découvertes au CHU de Lille, a permis de définir et de caractériser trois grands types de pathologies distinctes: les schwannomes intra-labyrinthiques, les labyrinthites, les hémorragies intra-labyrinthiques. Ces pathologies nécessitent des prises en charge différentes. Nous avons pu également définir des critères pronostics en particulier des critères de gravité nécessitant une prise en charge rapide adaptée. Dans le cadre ce travail de recherche sur les pathologies de l’oreille interne, nous nous sommes également intéressés au Syndrome de déhiscence du canal semi-circulaire supérieur, syndrome clinique récemment décrit par Minor en 1998. Une étude précise des cas découverts entre 2007 et 2009, associant le scanner HR de l’oreille et la fusion des images HR en IRM (fusion entre une séquence d’angio-IRM HR et la séquence 3D HR T2), a permis de mettre en évidence une variante de la forme classique, correspondant, non pas à une déhiscence osseuse isolée du canal semi-circulaire supérieur, mais à une déhiscence du sinus pétreux supérieur venant au contact du labyrinthe membraneux au niveau du canal semi-circulaire supérieur. La prise en charge chirurgicale étant très différente en cas de déhiscence vasculaire. Mon travail sur la base du crâne et l'imagerie haute résolution m'a également conduit à m'intéresser aux outils d'aide à la planification et à la prise en charge chirurgicale des tumeurs de la base du crâne. En effet, ces tumeurs, souvent bénignes, sont d'accès difficile en raison de l'importance des rapports nerveux et vasculaires à ce niveau. Le but est de développer une méthode de reconstruction tridimensionnelle de ces tumeurs dans leur environnement vasculaire et nerveux permettant au chirurgien de modéliser et de choisir sa voie d'abord. Ces reconstructions 3D des tumeurs de la base du crâne et de leur environnement montrent l’intérêt de l’imagerie HR de la base du crâne non seulement pour les radiologues mais également pour les chirurgiens et pour l’enseignement de cette région.

This book was released on 2012 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviews the role of endoscopic endonasal techniques During the last decade the endoscopic endonasal approach (EEA) to the skull base has become a very powerful method to add to the array of neurosurgical technologies. This volume provides a broad overview of the role of transnasal approaches in a wide spectrum of skull base diseases. It starts with a historical perspective of the evolution from the microscope to the endoscope in endonasal surgery and then explores in depth the principles and techniques of the various methods. Discussed are topics based on anatomical boundaries: pituitary fossa to the suprasellar space to the cavernous sinus, clivus and the anterior cranial fossa. Access to the infratemporal and posterior fossae via both the endoscopic endonasal and the retrosigmoid approaches are reviewed. In addition, the critical topic of reconstruction following 'minimally invasive' skull base surgery and finally the learning curve and complications associated with the applications of these new and exciting approaches are discussed. This volume will provide the latest knowledge to help neurosurgeons, otolaryngologists, head and neck surgeons as well as craniofacial surgeons understand the applications and practice of this important technique.

Download or read book Atlas of Head and Neck Imaging written by Suresh K. Mukherji and published by Thieme. This book was released on 2011-01-01 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designed for easy use at the PACS station of viewbox, here is your right-hand tool and pictorial guide for locating, identifying, and accurately diagnosing lesions of the extracranial head and neck. This beautifully produced atlas employs the spaces concept of analysis, which helps radiologists directly visualize complex head and neck anatomy and pathology. With hundreds of high quality illustrations, this book makes the identification and localization of complex neck masses relatively simple. This book provides CT and MR examples for more than 200 different diseases of the suprahyoid and infrahyoid neck, as well as clear and concise information on the epidemiology, clinical findings, pathology, and treatment guidelines for each disease. Each space within the head and neck has its own separate section, with examples of the common pathology that arises in this area. A standard format consisting of "Epidemiology, Clinical Presentation, Pathology, Treatment, and Imaging Findings," allows quick and efficient access to well-structured subjects. This uniform organization streamlines research for radiologists at any level of training. Although well over 200 pathologies are included within this remarkable text, Atlas of Head and Neck Imaging focuses primarily on the suprahyoid and infrahyoid neck, providing exceptionally detailed information on the most challenging aspects of this field. Radiologists and radiation oncologists will find this visual text ideal as a quick anatomic reference and diagnostic tool. Radiology residents preparing for board exams and neuroradiology fellows and staff studying for the CAQ exam will also benefit from the wealth of information.
Download or read book Color Atlas of Vascular Tumors and Vascular Malformations written by Odile Enjolras and published by Cambridge University Press. This book was released on 2007-04-02 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemangiomas and superficial vascular malformations are disfiguring birthmarks that can occur over 65% of a child's body. This atlas will focus on the classification, multidisciplinary approach, recognition and identification, and treatment options for this class of pathology. Vascular malformations, composed of malformed vessels, never regress and sometimes expand rapidly. They occur in any body part including viscera. They cause cosmetic problems, functional disability and can be life threatening and require radiologic imaging and pathology to recognize and perform differential diagnosis on various vascular anomalies. In addition, new techniques, including molecular biology procedures, have evolved allowing less invasive and a more effective approach to diagnosis and treatment.

Available in PDF, EPUB and Kindle. Book excerpt: “The reading of STRESS and ORALITY written by F. HARTMANN and G. CUCCHI led me to believe that we should consider the problem of certain migraines, neck pain, fibromyalgia, and chronic fatigue from a radically different angle than the historically traditional approach.” Pr Roger Guillemin (Nobel Laureate in Medicine) Are oral disorders only an issue for dentists? The answer is no. If your patients complain of pain and/or discomfort, if some are diagnosed as suffering from migraines, fibromyalgia or chronic fatigue, and if classical therapies have remained ineffective, this book could help in your daily practice. When it comes to the complex pathology called Temporo-Mandibular Disorders (TMD) most specialists favour a multidisciplinary approach and treatment of socio-psycho-emotional factors as well as dental, lingual or postural disorders. Yet little is known - from a clinical point of view - about a tricky oral spastic habit called severe teeth clenching. In view of the lack of clinical findings from classical investigations on the subject, it could be considered as the “hidden part of an oral parafunctional iceberg”. Neuroscience has been able to shed some light on the multiple connections between trigeminal and non-trigeminal nervous centres, which confirms the significant involvement of the stomatognathic system and trigeminal nerves (V) in both oral as well as non-oral major functions such as eating, breathing, speaking, hearing, and standing ... and also confirms the extensive participation of the paired Vs in the human adaptation process. Too many physicians are still reluctant to admit the pathological responsibilities of the Vs. Therefore their role remains largely underestimated by clinicians. Stress conditions in introverted people cause a parafunctional habit (i.e. severe clenching), which in turn produces trigeminal overstimulation and nociception. Through a process of sensitization this can perturb some non-trigeminal nervous areas, such as the vestibular nuclei and cerebellum (involved in equilibrium). Would you then be willing to accept the possibility that a stressed and introverted patient who clenches hard, durably or frequently may end up suffering from dizziness? If not, this book is not for you. But if you accept the scientific data and clinical facts this book will offer a concrete therapeutic protocol: the Relaxing and Moderating Treatment (RMT), which can greatly help you to familiarize yourself with and neutralize this little known deleterious spastic oral parafunction and its many disconcerting pain-causing and dysfunctional clinical effects. Prepare to be amazed by the results, just as we were!
Download or read book The Evo Devo Origin of the Nose Anterior Skull Base and Midface written by Roger Jankowski and published by Springer Science & Business Media. This book was released on 2013-03-19 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phylontogenic theory proposes an original understanding of nose, sinus and midface formation and development by looking back in evolution for the first traces of the olfactory organ and then tracing its successive phyletic transformations to become part of the respiratory apparatus and finally the central point of human facial anatomy. Von Baer’s, Darwin’s, Haeckel’s, Garstang’s, Gould’s and Buss’ explorations of parallels between phylogeny and ontogeny help to trace the nose and midface story. The paradigm of existing parallels between ontogeny and phylogeny proves useful both in seeking to understand the holoprosencephalic spectrum of facial malformations (which represent radically different pathways of facial development after the life’s tape has been started to run again) and in formulating hypotheses on chordate to vertebrate evolution. The phylontogenic theory leads to new medical hypotheses on nose and sinus diseases and opens the field of evolution and development-based medicine.
Download or read book Diseases of the Sinuses written by Christopher C. Chang and published by Springer. This book was released on 2014-06-06 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diseases of the Sinuses: A Comprehensive Textbook of Diagnosis and Treatment, 2nd Edition, offers the definitive source of information about the basic science of the sinuses and the clinical approach to sinusitis. Since the widely praised publication of the first edition, understanding of sinus disease has changed dramatically, mainly as a result of recent developments and new discoveries in the field of immunology. This updated and expanded edition is divided into sections addressing, separately, the pathogenesis, clinical presentation, medical and surgical management of acute and chronic rhinosinusitis. Special entities such as autoimmune-related sinusitis, allergy and sinusitis, and aspirin-exacerbated respiratory disease are discussed in separate chapters. The role of immunodeficiency is also addressed. The management section has been fully updated to incorporate new medical modalities and surgical procedures. Developed by a distinguished group of international experts who share their expertise and insights from years of collective experience in treating sinus diseases, the book will appeal to anyone who has an interest in sinus disease, including both physicians and allied health professionals. Internists, pediatricians, allergists, otolaryngologists and infectious disease specialists will find the book to be an invaluable, comprehensive reference. Physician assistants and nurse practitioners who work with specialists who treat sinus disease will also benefit from the book.
