A TOTAL of 157 patients with clinical and audiometric findings suggestive of cochlear otosclerosis and tomographic evidence of capsular changes have been treated with sodium fluoride (NaFl) and then re-examined by tomography. The time interval between the first and following radiographic examinations ranged from a minimum of six months to two years.
The Table shows the distribution of the 157 patients according to age from the larg
est group which was in the 40's it tapers down on either sides, the youngest patient being 14 and the oldest 76. A total of 111 or 71% of the patients showed no change in the degree, extension, and type of involvement following NaFl therapy.
In nine cases (5.5%) a worsening of the capsular involvement was noticed due either to increase in size of the focus or foci or extension of the involvement to other portions of the cochlear capsule.
