Many patients with temporomandibular disorder and coexisting tinnitus find that therapy improves or resolves their tinnitus in conjunction with their TMD symptoms. Ninety-three patients with TMD who reported having coexisting tinnitus were questioned and given clinical tests. These assessment instruments were then evaluated for their ability to suggest tinnitus improvement as a result of TMD therapy. This study suggests that asking targeted questions and performing a clinical test could be of significant value in helping practitioners identify which patients with TMD and coexisting tinnitus will experience improvement in, or resolution of, their tinnitus when TMD symptoms have improved significantly.
