The development that has characterized ENT in recent years is extremely impressive. Much has to be attributed to advances in sensory physiology with which this specialty is intimately linked. For example, developments in auditory neurophysiology have revolutionized the assessment of inner ear disorders and paved the way for such important advances as cochlear implantation. The skull base, previously a surgical "no man's land" is now eminently accessible using microsurgical techniques. Endoscopic surgery has had a major impact on the understanding and treatment of nasal and sinus disorders and advanced the evaluation and surgery of the larynx and trachea. Better reconstructive techniques have become available to minimize morbidity from major head and neck resections. The use of lasers and microvascular techniques have been expecially valuable. Voice disorders, cosmetic surgery, sleep disturbance and molecular biology are examples of other areas engaging much of the ENT surgeon's attention. In this book, care has been taken to cover the basics of ENT assessment, and common clinical conditions are presented in a concise manner. The text has been designed to be as accessible as possible and is copiously illustrated throughout for clarity. The "Key Points" of each section are condensed into special sections to emphasize the essentials. The book should be of help to family practitioners, casualty officers, paediatricians, and physicians.
