DISEASES OF THE EAR IN CHILDHOOD

DISEASES OF THE EAR IN CHILDHOOD DISEASES OF THE EAR AND AGE OF PATIENT Each period of life—childhood, middle age and old age—has its own peculiar type of ear trouble. With few exceptions, the person who has passed the age of 50 has a greater or lesser defect in the upper tone ranges, the result of degeneration of the cochlear nerve. Such defects involve primarily the upper tone range and therefore interfere but little with the hearing of the voice; only exceptionally do they progress so far as to constitute a serious handicap. During middle life there is a different form of ear trouble, usually beginning in early adult life. Like the process which involves the eighth nerve in old age, this disease of the ear which occurs during adult life is produced by changes that are permanent. The alterations are primarily not of the nerve, but are such as to produce fixation or rigidity in http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American journal of diseases of children American Medical Association

Abstract

DISEASES OF THE EAR AND AGE OF PATIENT Each period of life—childhood, middle age and old age—has its own peculiar type of ear trouble. With few exceptions, the person who has passed the age of 50 has a greater or lesser defect in the upper tone ranges, the result of degeneration of the cochlear nerve. Such defects involve primarily the upper tone range and therefore interfere but little with the hearing of the voice; only exceptionally do they progress so far as to constitute a serious handicap. During middle life there is a different form of ear trouble, usually beginning in early adult life. Like the process which involves the eighth nerve in old age, this disease of the ear which occurs during adult life is produced by changes that are permanent. The alterations are primarily not of the nerve, but are such as to produce fixation or rigidity in
