Currently, most hearing loss cannot be helped by surgery or medications. The most appropriate treatment for most sensorineural and some conductive hearing loss is with properly fitted hearing aids. This textbook, representing the collaborative efforts of leading otologists and audiologists, is designed for otolaryngologists, both those in training as well as in practice, to enhance the basic knowledge of hearing aid mechanics and dispensing taught in residency programs. The text has informative chapters on special testing, real-ear measurements, the requirements of fitting the pediatric patient with hearing loss, as well as the patient with tinnitus and hearing loss that otolaryngologists can expect to see commonly in practice. The increasing body of the "science" of hearing aid fitting is addressed in chapters covering evidence-based prescribing of hearing aids, as well as future trends to be expected in hearing aid and otologic research. Practical suggestions on professional marketing of hearing aids, as well as a breakdown of the economics of hearing aid dispensing to enhance profitability in today's increasingly difficult practice environment are also well covered.The text is sure to enhance the knowledge base of the otolaryngologist in one of the fastest growing areas within the specialty.
