While at the time we questioned the necessity for an additional book in the area of craniofacial pain, this worry soon became unnecessary. The book was accepted with great enthusiasm, and in 2009, the British Medical Association highly commended the fi rst edition as one of the best books published in the medical fi eld. Reviews were complimentary: “This text- book is a joy to read,” proclaimed a 2008 review in the Journal of Orofacial Pain (Quintessence Publishing). The reviewers praised our success in integrating the broad topics of orofacial pain and headache. Furthermore, we were glad to see that this most important journal in the orofacial fi eld changed its name in 2014 from the Journal of Orofacial Pain to the Journal of Oral & Facial Pain & Headache, pointing to what was already obvious to us; these two fi elds must continue to be integrated. Integration ensures that we are consistent and relate all regional craniofacial pains to each oth- er, thereby presenting the wider picture of craniofacial pain syndromes and the overlap between primary headaches and primary orofacial pain entities. Truly, the years since the fi rst edition was published have seen some integration of the two fi elds, particularly through close collaboration be- tween dental and medical professionals for the preparation of the 2013 International Classifi cation of Headache Disorders. In spite of this, the International Headache Society’s classifi cation system does not yet adequately cover all currently accepted orofacial pain entities. Therefore, we added the recently reviewed classifi cation of the Diagnostic Criteria for Temporomandibular Disorders (DC- TMD) and drew from our wide experience in the fi eld. Certainly, in the diagnosis of acute dental and otolaryngological pain, we have continued to stress the importance of accurate, evidence-based diagnosis. This may seem oversimplistic at fi rst, but consider the reports of misdiagnosis of cluster headache, paroxysmal hemicrania, migraine, and trigeminal neuralgia as dental pains or sinus head- aches. The results to our patients are often devastating and unnecessary. Clearly as a profession, we still have hurdles to overcome. While we preserved the well-structured format of the last edition, we updated the chapters to refl ect current knowledge and added a new chapter on orofacial pain and sleep, as data continues to point to their interconnection. We have also made this edition friendlier to clinicians. In many chapters, we fi rst address the clinical picture and treatment strategies and follow with a discussion of the underlying mechanisms. In addition, the design has been updated, and we have found that the esthetic layout of the present edition, made possible by the excellent editors and production staff of the Quintessence Publishing house, makes the excursion through the pages of this book a most pleasant experience. Finally, as the fi rst edition was highly praised, we felt that we were not in a position to disappoint our faithful readers and had to keep to the high standards that are expected. We very much hope we have succeeded in this mission. vii Preface to the First Edition or many years, the area of orofacial pain was completely dominated by the concept that most facial pains were due to “disturbed function” of the temporomandibular joint (TMJ). F This was an approach established by an otolaryngologist named James B. Costen who linked etiology to derangements of the dental occlusion; facial pain was thus handed over to den- tistry. As a profession, we enthusiastically adopted the treatment of facial pain but have for many years concentrated our efforts on a mechanistic approach to treatment. These events essentially segregated facial pain from headache and, in effect, from mainstream medicine. As a result, ideal conditions were established in each of the two disciplines for the development of different ap- proaches to the understanding of mechanisms and therapy of craniofacial pain. However, as our understanding of pain mechanisms, and in particular chronic pain, developed, it became clear that facial pain has underlying neurophysiologic mechanisms common to headaches and other body areas. Masticatory muscle pain was examined in light of other regional muscle pains, and management of the TMJ was related to, and brought in line with, basic orthopedic principles. Most importantly, features of some facial pain entities are very similar to those of some head- aches. Examples include masticatory myofascial pain and tension-type headache and a facial equivalent of migraine. The dental profession has been slow in adopting medically based classification and approaches to therapy. In a similar fashion, the medical profession has been very resistant to incorporating es- tablished facial pains into current classifications; temporomandibular disorders are a prime example and currently unrecognized by the International Headache Society. One may correctly claim that toothache is unique, but is it really? On a mechanistic level, pulpitis is an inflammatory process within a confined space—not very different from the inflammatory pro- cess of migraine confined within the skull. Indeed, we believe that migraine-like mechanisms exist within the pulp chamber mimicking pulpitis, in the paranasal sinuses imitating sinusitis, and in other confined cranial structures causing atypical symptomatology. In each of these cases, anti-migraine medications are the correct treatment. Clearly the task required is integration of knowledge in this anatomically dense region, tradi- tionally divided between many medical disciplines. Based on our extensive clinical experience with patients suffering from orofacial pain and headache as well as our thorough understanding of pain mechanisms specific to the trigeminal system, we feel that we are well equipped to fulfill this task. This textbook therefore deals with oral and facial pain as well as with headaches and aims to inte- grate the knowledge across these disciplines. We hope we have succeeded. We appreciate the contribution of our teachers, colleagues, and students. Throughout our pro- fessional
