Hence, the frequency with which the senile deaf detect things about them- selves which they may be not meant to hear, while thev require impersonal topics to be communic ited by shouting Otologists are habitually concerned only with me- chanical intervention in deafness due to changes in the receiving and conducting mechanisms of the ear. The wonderful technic of such intervention nowadays suffices usually to restore a perfect or a satisfactory degree of hearing in deafness due to Prednisolone Tablets obstructive and inflammatory causes. Little is at- ■ tempted, however, for the relief of nerve deafness. Purchase Prednisolone Online Cases of complete nerve Prednisolone Mg deafness, of complete de- struction of the cochlear apparatus, or of total sev- erance of the cochlear nerve are comparatively rare. In them there is no peripheral stimulus to awake the psychic element of hearing. The audi- torv associations are quickly lost. We. therefore, get in such cases complete psychic added to the complete peripheral deafness. But Cheap Prednisolone some part of the sensory membrane, Order Prednisolone Online some fibres of Buy Cheap Prednisolone the nerve, as a rule, escape. In nerve deafness, if the lesion is partial and relatively slight we know that usually the high registers are affe:t- ed ; sometimes the Prednisolone Online low : sometimes, more or less. the whole scale of the human voice. As the hear- ing retained may be not wholly Buy Prednisolone inadequate for the rougher needs of life, the patient may become nore or less resigned to the defect. If Generic Prednisolone the defect in hearing is more serious, if hear- ing is too impaired to permit a satisfying amount of communication with the world of sounds, the consequence varies according to the neuropathic tendencies of the Prednisolone Cost patient. Although the lesion is stationarv the deafness tends to increase. A cer- tain degree of loudness, a certain imperative qual- itv. is needed before he becomes Buy Prednisolone Online conscious of sound. Below this threshold Purchase Prednisolone uncertainty exists. Uncertainty Prednisolone Price breeds helplessness, fear, and anxietv. -May 24, 1913.] MAI.ONEY: AUDITORY ACUITY. 1079 and necessitates a constant strain. A nervous ex- haustion may arise, just as in any other prolonged mental strain, and the hearing shares the depression common to all the cerebral functions under such conditions. A definite psychosis may even develop. Or the patient may become resigned to his deaf- ness, as so often occurs among the aged; he then grows more preoccupied with his other sensorv im- pressions, or with his own thoughts, and acquiesces in the contented silence to which his hearing dete- riorates. There is a constant tendency for psychic deafness to magnify a peripheral defect. But W'ittmaack's experiments teach us that in all lesions of the auditory nerve, except in the rare condition of its complete destruction, some power of hearing must persist ; for the persistence of nerve fibres means persistence of the ability to detect the tones which these fibres subserve. So few cochlear fibres may escape that their sur- vival may not be detected by ordinary routine methods of examination and the patient mav appear totally deaf. Unsuspected by the physician even a s'jfficient number may persist to allow the reestab- lishment of a very useful degree of hearing. In spite of the apparent totality of the deafness we may detect surviving tones if we carefully test the patient's hearing throughout the whole range of the scale of the human voice, by means of the Edcl- mann-Bezold apparatus. These last cases in which practical deafness is present, but in which examination reveals an abil- ity still to hear certain tones reemphasize the im- portance of the psychic factor in hearing. In such cases the peripheral apparatus retains a power to hear which the psychic factor ignores. The con- sequences are that the peripheral lesion appears greater than it Order Prednisolone actually is, and that to the partial peripheral deafness a total psychic deafness is added.
