Internal Fixation Of The Mandible

The rigid internaI fixation of mandibular fractures has become a widely ac cepted practice among European surgeons. The caution or even outright re jection voiced at a congress of the German Society of Maxillofacial Sur 1970s is no longer prevalent. Through a process of geons held in the late critical review and implementation, rigid internaI fixation has become an established treatment modality at numerous centers, especially in Switzer land, the Federal Republic of Germany, and the Netherlands. By comparison, the method has received very little attention in North America and the Anglo-Saxon countries. By and large, surgeons in these countries continue to treat mandibular fractures by intermaxillary fixation, possibly supplemented by the use of interosseous wires. Many recent edi tions of surgical texts confirm this. Lately, however, there appears to be a surge of interest in methods of functionally stable internaI fixation, especially in the United States of America, and AO/ ASIF instruction courses are increasingly in demand. This book is intended to aid course participants in their lessons and practi cal exercises and also to guide the clinical practitioner in the application of AO/ ASIF principles.

The colleagues of the past 20 years who have contributed to the case material upon which this manual is based are too numerous to credit by name.

The atlas format of Craniomaxiollofacial Fracturesclearly shows how to manage fractures to the head, face and jaw bones with rigid internal fixation. All fractures, from the simple to the most complex, are covered. The book is ideal for physicians from various specialties who diagnose, treat or refer craniomaxillofacial trauma. It describes for the first time the classical fracture types most commonly encountered and their representations by standard radiographs and diagrams. The AO system is prominently featured throughout the atlas.

This manual provides comprehensive information on the surgical techniques in internal fixation of fractures, in restoring tumour defects, and osteotomies in the craniofacial skeleton. Through detailed and instructive drawings together with clinical situations shown on x-rays it offers important guidelines for the surgeon in the operating room. The techniques are based on the general principles developed and continuously refined by the AO/ASIF group. This manual constitutes the written guideline of the surgical techniques as taught in the AO/ASIF courses and workshops throughout the world.

This is an open access book with CC BY 4.0 license. This comprehensive open access textbook provides a comprehensive coverage of principles and practice of oral and maxillofacial surgery. With a range of topics starting from routine dentoalveolar surgery to advanced and complex surgical procedures, this volume is a meaningful combination of text and illustrations including clinical photos, radiographs, and videos. It provides guidance on evidence-based practices in context to existing protocols, guidelines and recommendations to help readers deal with most clinical scenarios in their daily surgical work. This multidisciplinary textbook is meant for postgraduate trainees, young practicing oral surgeons and experienced clinicians, as well as those preparing for university and board certification exams. It also aids in decision-making, the implementation of treatment plans and the management of complications that may arise. This book is an initiative of Association of Oral and Maxillofacial Surgeons of India (AOMSI) to its commitment to academic medicine. As part of this commitment, this textbook is in open access to help ensure widest possible dissemination to readers across the world. ; Open access Unique presentation with contents divided into color-coded core competency gradations Covers all aspects of oral and maxillofacial surgery Supplemented with videos of all commonly carried out procedures as operative video Every chapter or topic concludes with "future perspective" and addresses cutting edge advances in each area Every topic has a pull out box that provides the most relevant systematic reviews/ key articles to every topic.

Since 1958 the Association for the Study of Internal Fixation (ASIF) has worked to establish the experimental and biomechanical prin ciples of the operative treatment of fractures. It has been proven that immediate, pain-free mobilization, made possible by stable internal fixation, is the key to restoring function in a fractured extremity. The same principles were applied in 1972173 by Roland Schmoker, who developed a universal plate and sophisticated instrument set designed initially for the treatment of comminuted fractures of the mandible. To extend the applications of his plate to reconstructions after ex tensive tumor resections, he supplemented the device with tem poromandibular joint prostheses and anchoring elements for the at tachment of dentures. He first tested the functional stability of these implants experimentally in sheep. Later he found that the minipig had a more human-like jaw shape and masticatory action, and so he tested the implants in 37 mini pigs that underwent extensive mandibular re sections without bone grafting, using sequential dye injections and postoperative weight gain to chart the progress of osseous regener ation. Seven other animals were not operated and served as controls.

Functionally stable internal fixation is of particular relevance to maxillo facial surgery, because it obviates the discomforts and inconveniences of intermaxillary fixation. Given the biomechanics and biophysics of the skeletal system, the true im mobilization of bone can be achieved only through highly technical means. Willenegger speaks of an "advanced school" of bone surgery which, when fully realized, will enable excellent results to be achieved even in the most difficult fractures. To accomplish this goal, ongoing refinements are needed in surgical methods and technology. Advancing the state of operative tech nique has been a central concern of the Association for the Study of Inter nal Fixation since its establishment 25 years ago. For this reason, a major priority of the AOI ASIF has been to develop its own surgical instrumen tation. With the help of technical commissions comprised of experts from medi cine, research and manufacturing, the AOI ASIF has been able to develop and successfully test a line of surgical instruments whose trademark is known and respected the world over. For every specialty in traumatology and orthopaedics, including maxillofacial surgery, the AOIASIF has devel oped both a basic and a special instrument set designed to meet specific anatomic requirements.
