This definitive reference work replaces Konigsmark and Gorlin's Genetic and Metabolic Deafness (1976). Whereas the earlier volume covered 151 genetic conditions related to hearing loss, this work covers 435. As before, the authors first discuss isolated hereditary hearing loss and then present hearing loss syndromes such as those involving the nervous system, eye, external ear and musculoskeletal system. The discussions are authoritative, practical and well-illustrated, and those of the most important syndromes are very detailed. Introductory chapters deal with the history of the field, clinical approach, embryology of the ear, tooth anomalies and hearing loss, and related endocrine and metabolic disorders. Throughout, the authors pay careful attention to nomenclature and classification. This will be an invaluable resource for all professionals concerned with genetic hearing loss, including medical geneticists, audiologists and otolaryngologists.
