At the patient's first visit to the author's office, neurotologic testing with tuning forks revealed diplacusis at 512, 2,048, and 4,096 Hz.
At follow-up 3 months later, the patient reported that the diplacusis had become a little worse, the aural fullness more pervasive, and the hyperacusis worse on the days he took the risedronate.
The patient returned in another 3 months and reported that the diplacusis was better toward the end of the etidronate cycle but worse on days when he took risedronate.
Four months later, no change had occurred in the diplacusis; it remained better toward the end of the etidronate cycle and worse during the days on risedronate.
Six months later, which marked the 16th month of treatment overall, the patient returned (and brought with him an article on monaural diplacusis (1)).
