Cancer of the head and neck continues to be a challenge. Increasing incidence has pushed malignancy of the upper aerodigestive tract into the first rank of cancer. In some countries it follows bronchial carcinoma in frequency and is more common than gastro-intestinal and gynaecological cancer. This increasing incidence makes it difficult to train enough highly specialised staffwho are also responsible for the care of many other patients, requiring sophisticated microsurgery of the ear and nose. The question of quality is even more difficult. Oncological success in the treat ment of head and neck cancer is bought at the price of crippling of vital functions such as eating, breathing, voice and sight and furthermore of striking aesthetic de formity. Mutilation of this highly functional collection of organs is more keenly felt than that of any other region of the body. It is vital, therefore, that the surgeon keeps up with the recent achievements of functional surgery in order to offer the best ser vice to his patients. Cancer of the larynx is no exception. Despite newer techniques of radiotherapy and chemotherapy, surgery still gives the best oncological results. This requires a wide spectrum of operations varying from minimal ablation to total laryngectomy."

Singing has been a characteristic behaviour of humanity across several millennia. Chorus America (2009) estimated that 42.6 million adults and children regularly sing in one of 270,000 choruses in the US, representing more than 1:5 households. Similarly, recent European-based data suggest that more than 37 million adults take part in group singing. The Oxford Handbook of Singing is a landmark text on this topic. It is a comprehensive resource for anyone who wishes to know more about the pluralistic nature of singing. In part, the narrative adopts a lifespan approach, pre-cradle to senescence, to illustrate that singing is a commonplace behaviour which is an essential characteristic of our humanity. In the overall design of the Handbook, the chapter contents have been clustered into eight main sections, embracing fifty-three chapters by seventy-two authors, drawn from across the world, with each chapter illustrating and illuminating a particular aspect of singing. Offering a multi-disciplinary perspective embracing the arts and humanities, physical, social and clinical sciences, the book will be valuable for a broad audience within those fields.

Many congenitally deaf infants and children suffer vestibular failure, which produces problems with their postural control, locomotion and gait. However it is known that these children can eventually catch up with their normal balance control status in terms of development and growth as a result of central vestibular compensation. In Vertigo and Balance Disorders in Children the author provides comprehensive and integrative information on the vestibular system. The materials presented range from the history of its study, basic anatomy and physiology of vestibular organs, mechanism of balance and motor function development, to clinical aspects of vestibular disorders including their evaluation and pediatric neurology. Although there have been books discussing postural responses of infants and children with vestibular disorders, this is the first to present the influence of peripheral vestibular disorders and central vestibular compensation comprehensively. This book will benefit not only practitioners in this field such as pediatric otolaryngologists, pediatricians, child neurologists and neurologists, but also clinical specialists such as neonatologists, physical therapists and speech therapists, helping them to better care for patients with vestibular failure.

One of the fastest growing areas in Otolaryngology today is sleep medicine. More than one third of all adults and children with sleep disorders present initially to an otolaryngologist for diagnosis and treatment, but there is a paucity of available educational material written from and for the ENT perspective. Designed for clinicians, residents, and otolaryngologists wanting to sit for the American Board of Medical Specialties' conjoint Board Certification in Sleep Medicine which, on implementation in 2007, allowed Board Certified Pediatricians, Otolaryngologists, Neurologist/Psychiatrists and Pulmonologists to sit for the exam, this new book was put together by 2 of the only 49 Otolaryngologists who were board certified in sleep disorders in 2008. Sleep Medicine features chapters from experts in other related fields, provides materials necessary to practice sleep medicine, covering the basics of both adult and pediatric sleep medicine as it applies to the clinical practice of Otolaryngology.It is the only book to provide an in-depth review of clinical sleep medicine with coverage of sleep testing modalities and to focus on the clinical sleep disorders that an otolaryngologist is likely to see in the office. The evaluation, including history, examination and testing, are detailed with clinical examples; Treatment options, including Positive Airway Pressure, Mandibular Advancement Devices and Surgical Treatments are discussed with regard to efficacy, patient selection and appropriate follow-up; and an extended section focuses on the evaluation of the sleepy or fatigued patient, a group frequently seen by otolaryngologists with etiologies possibly due to causes other than obstructive sleep apnea. From the foreword: "Sleep Medicine will be the only clinical sleep disorders book that will be extremely useful to Otolaryngologists practicing sleep medicine or desiring to learn the clinical aspects of sleep medicine. This will be a welcome addition to the sleep medicine arsenal of literature and useful to other practitioners who are looking for a no-frills textbook that is primarily focused on the evaluation and therapy of patients with sleep disorders.Although there are several chapters addressing various therapeutic and surgical approaches to the patient with sleep disordered breathing, do not think this is only useful for an otolaryngologist!This will be a very handy clinical reference manual since the editors took extra care to make sure this book also represents the multidisciplinary scope of the field.

Written for residents and practitioners of otolaryngology, medical oncology, radiation oncology, and maxiollofacial surgery, this book provides the reader with a comprehensive, concise discussion of the best evidence available on which to base clinical decisions needed when managing patients with squamous cell carcinomas of the oral cavity, pharynx and larynx. Because of its accessible and practical format, this book is considerably different than other related titles on the market. Formatted with questions at the beginning of each chapter that are then answered with evidence and best practices available for each case, each chapter addresses situations the clinician is likely to face in the diagnostic evaluation and treatment of a patient with cancer of the head and neck. Most clinical decisions in the management of cancers of the head and neck region are based on the results of a few controlled, randomized clinical trial trials (Evidence Level I). However, most decision-making is based on the results of case-control studies (Evidence Level II), descriptive studies, reports of expert committees, or opinions of respected authorities (Evidence Level III). This information is scattered throughout the literature and often comingled with information about other topics. Therefore, there is a need for a publication in which the evidence pertinent to making decisions regarding a particular clinical problem is distilled from the literature and presented in a single concise, clinical, situation-driven source. Cancer of the Oral Cavity, Pharynx and Larynx: Evidence-Based Decision Making is just such a resource.
