Cholesteatoma and Anterior Tympanotomy available in PDF, EPUB and Kindle. Acquired aural cholesteatoma poses a unique procedural dilemma with regard to pathogenetic research and theory building. Because cholesteatoma spontane ously occurs only in the poorly pneumatized human ear, its pathogenesis is specific to humans. Nonetheless, because of the ethical questions surrounding human experimentation, pathogenetic study has almost exclusively involved nonhuman subjects. Indeed, attempts have failed in almost all animal expe riments except with the gerbil, and even here experimental designs have been improbable compared with human cholesteatoma. Cholesteatoma in the gerbil is useful, therefore, only for the study of pathology and not for human pathogenesis. I hold that the pathogenesis of cholesteatoma will be understood by studying the cholesteatomatous ear, that is, the malpneumatized ear of the human. The anatomical difference between the normal and malpneumatized ear is a probable cause of cholesteatoma. This difference may be found clinically in facial nerve decompression and cholesteatoma surgery, as, for example, facial nerve palsy occurs usually in the normal, well-pneumatized ear. Of course, conventional animal experimentation will not confirm this clinical difference since there is no ideal animal model for the poorly pneumatized human ear. Present surgical techniques for cholesteatoma vary greatly according to indi vidual otosurgeon's opinion. The most extreme difference of opinion is focused on whether to remove the external ear canal wall. Normally, the best option would be not to remove the canal wall if cholesteatoma recurrence can be prevented. Simply put, recurrence of cholesteatoma comes about when its cause has not been removed during primary surgery.

Download and read online ebook Tympanic Membrane Retraction Pocket write by Salah Mansour. This book was released on 2015-02-27. Tympanic Membrane Retraction Pocket available in PDF, EPUB and Kindle. This book reviews current knowledge of the etiopathogenesis, pathophysiology, and molecular biology of tympanic membrane retraction pockets and provides clear guidance on clinical assessment and treatment. A new diagnostic approach based on clinicoradiologic correlations is presented, and the ability of computer tomography to offer objective criteria for improved differentiation between stable and unstable or unsafe retraction pockets is explained. Surgical options are discussed, and on the basis of their own clinical and surgical experiences the authors propose a novel procedure, masto-atticotomy with anterior epitympanotomy (AER surgery), which addresses the causative factors underlying a retraction pocket. This surgery aims to restore adequate aeration routes for the middle ear compartments situated above the tympanic diaphragm; it results in better control of the pathology and in most cases prevents its recurrence. The book will assist otologists and surgeons in ensuring that retraction pockets are effectively diagnosed and treated, avoiding progression to cholesteatoma.

Download and read online ebook Microsurgical Management of Middle Ear and Petrous Bone Cholesteatoma write by Mario Sanna. This book was released on 2019-07-10. Microsurgical Management of Middle Ear and Petrous Bone Cholesteatoma available in PDF, EPUB and Kindle. The key reference dedicated to surgery for cholesteatoma... The cholesteatoma, strictly speaking a cyst and not a cancer, nevertheless shows expansive and destructive growth patterns that may give rise to serious symptoms and consequences, including fatality, not unlike those seen for malignant neoplasms. The great challenge of therapy is to eradicate the pathologic growth while preserving hearing and other critical functions of the middle ear and petrous bone, respecting the proximity of vital neural and vascular structures, and the intricate three-dimensional relationships involved. Mario Sanna's Microsurgical Management of Middle Ear and Petrous Bone Cholesteatoma is the ultimate illustrated guide to complete management of the cholesteatoma, including assessment of the full expansion and degree of destruction caused by the growths, and short- and long-term follow-up to assess and treat for recurrence. Key Features Brilliantly illustrated with diagnostic images from otoscopy and radiology, both normal and pathological Step-by-step description of approaches and techniques for the procedures Special coverage of petrous bone cholesteatoma, which is less frequent than other forms but more difficult to diagnose and treat, with introduction and description of a new function-sparing procedure, the subtotal petrosectomy Microsurgical Management of Middle Ear and Petrous Bone Cholesteatoma extends Mario Sanna's passionate dedication to excellence in otologic teaching and training into this highly complex surgical area. Practitioners, residents, and fellows will find it indispensable.

This book was released on 2011-10-28. Cholesteatoma available in PDF, EPUB and Kindle. Master the challenges of cholesteatoma management with this definitive reference Thieme congratulates Eric E. Smouha on being chosen by New York magazine for its prestigious Best Doctors 2015 list. In this succinctly-organized text, leading specialists have created a comprehensive guide to cholesteatoma and chronic ear disease. Based on the bestselling AAO-HNS course, Cholesteatoma provides in-depth advice for the medical and surgical management of this middle ear entity. Cholesteatoma begins with an introduction of the disease and its general considerations, including preoperative assessment, the role of imaging, and the wet ear. Comprehensive chapters then present the three components of middle ear surgery which are the middle ear, the mastoid, and the meatus and the resultant cavity. The expert authors provide perspective on the controversies in cholesteatoma management like canal wall reconstruction, facial nerve monitoring, the use of endoscopes in chronic ear surgery, and postoperative care. Features: Accompanying online media includes 20 surgical videos performed and narrated by the authors More than 340 vibrant full-color illustrations demonstrate the different disease progressions not shown in any other text Insightful chapters cover recidivism and complications of both the disease and surgery, while O.R. cases illustrate surgical approaches Otolaryngology-head and neck surgeons, residents and fellows will refer to this concise reference on a daily basis for the most up-to-date information on cholesteatomas and other middle ear lesions.
