  • Abstract
  • Look Inside

The therapeutic applicability of the low-frequency square current on external canal of the severe deafness was studied.

Eighty-five per cent among 20 deaf cases that had shown electrically hypo-excitability (index a/b2 was smaller than 0.1) recovered 20 db. or more in estimating at the standard hearing level. A few 25% among 16 deaf cases whose index a/b2 was above 0.1 proved to be improved with their hearing. The rest 75% did never. Four children, on which au-ditory chronaximetry 'could not be surveyed, had no chance to effectually receive this ther-apeutic application.

In conclusion, low-frequency square current is applicable as a treatment improving the acoustic aquity of the deafness accompanied by the hypo-excitability, to which the so-call-ed neural deafness would be id entified.
