This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1896 Excerpt: ... adenoid masses from the nasopharynx. This was followed by further improvement in hearing, and she can now carry on conversation more easily, and indeed acts as the interpreter between her younger deaf brother and the writer. She is 14 years old. A. F., aet. 5, was also born deaf. When three years old he heard and spoke nothing. About this time his hearing began to appear without treatment. Now he distinguishes vowels and a few numbers imperfectly. He is brother to the above B. F. Cases of this kind suggest two important points: 1. Congenital deafness does not mean total absence or destruction of the internal ear, and there may be a development of the organ, and certainly there is sometimes a development of its function long after birth. 2. Treatment applied to the middle ear and naso-pharynx may remove causes which accentuate an already existing deafness due to absence or destruction of parts of the internal ear. The prognosis, therefore, in congenital deafness is not altogether bad. So strongly was the father of these two patients convinced of this, that he has every confidence that his boy of five will, in time, hear like his girl of fourteen. He does not stake their chances so much on treatment as on the proof he has that their hearing has improved, and is now improving spontaneously. In acquired cases, the prognosis appears to depend on: 1. The amount of remaining hearing. 2. The presence of curable disease in the accessible parts of the organ of hearing--the middle ear and naso-pharynx. 3. The date of onset of the deafness. That the remaining hearing of a deaf mute is not a stationary quantity the writer feels quite sure. Many deaf children admitted to our institutions with a remnant of hearing are found when tested to have lost much of that remnant. ...
