Tinnitus: a theoretical view and a therapeutic study using amylobarbitone.

A hypothetical discussion of the mechanisms producing tinnitus has been described along with an outline of previous treatments given. A small group of 40 patients with troublesome tinnitus were studied, 20 of whom were treated with amylobarbitone, and the results have been presented. An attempt is made to compare the subjective assessment made by patients of their symptom with an audiometric assessment of the same symptom both before and after the study.
