A collection of 1002 patients with severe tinnitus, drawn from the Tinnitus Data Registry, were retrospectively surveyed to determine which traits or attributes of tinnitus could indicate the possibility of temporomandibular joint dysfunction (TMD) as the cause of tinnitus. The patients were divided into two groups: (1) a TMD group, consisting of 69 patients for whom there was no known cause of tinnitus except for one or more temporomandibular joint (TMJ) indicators, and (2) a comparison group with mixed etiologies (n = 860). Seventy-three patients were eliminated due to excessive complications relating to cause. The two groups were compared seeking those attributes of tinnitus that significantly separated them. No single benchmark standard was discovered that exclusively indicated tinnitus from TMJ origins. However, a total of 10 "TMJ Indicators" were discovered. The data for each of these indicators is presented and discussed. In addition, the attributes that did not significantly separate the two groups are listed. The study concludes with a recommendation for TMJ referral for those tinnitus patients with unknown etiology who demonstrate any three or more of the TMJ indicators.
