Observations Cliniques Sur Le Traitement Radio-Acoustique De La Surdité

Abstract

The Manfredi's radioacoustic treatment of deafness rouses an adequate stimulation of the neurosensorial structures. As for the indications, they principally consist in hypacousis of the perceptive type, towards which the otologist was, one might say, altogether at a loss. It is necessary to consider that when the hypacousis of transmission becomes serious, it causes a cochlear recession to such an extent that also in cases of otosclerosis important improvements have been attained.

The absolute absence of any risk or inconvenience makes the radioacoustic method a treatment to be attempted at all events. Regarding the so-called cofo-surgery, they are cases of otosclerosis that through the radioacoustic treatment have attained such an improvement, that surgery was unnecessary; other cases in which the surgical prognosis was very doubtful on account of the presence of a considerable perceptive component, the surgical operation was made possible owing to the radioacoustic treatment; and finally other cases improved by the operation of mobilizing the stapes in regard to the transmission component, have completed the success by means of the radioacoustic treatment that, acting on the neurosensorial apparatus, has integrated the surgical results.

Also concerning acoustic prothesis, there is no doubt that there are cases of deafness that improved to a point to enable to dispense from recurring to the prothesis; but there are other cases in which the radioacoustic treatment allows the patient to make use of the prothesis.
