Summary:summary  The literature has documented a controversial discussion on the possible relationship of otogenous symptoms and craniomandibular dysfunction since the 1920s. Therefore, an investigation was conducted which consisted of two parts: a case study with population‐based controls and a cross‐sectional study. The aim of the first study was to screen a group of patients suffering from acute or chronic tinnitus for temporomandibular disorders (TMD) in comparison with a population‐based group of volunteers without tinnitus. To this end, 30 patients (13 females and 17 males, age 18–71 years) suffering from acute hearing loss associated with tinnitus, isolated acute tinnitus, and chronically transient tinnitus were examined for symptoms of craniomandibular dysfunction. The results were compared with those of clinical functional analysis from 1907 subjects selected representatively and according to age distribution from the epidemiological ‘Study of Health in Pomerania’ (SHIP); the occurrence of tinnitus was ruled out in these control subjects. Statistical analysis was performed with Chi‐square and Mann–Whitney U‐tests. Sixty per cent of the tinnitus patients and 36·5% of the control subjects exhibited more than two symptoms of TMD (P = 0·004). Tinnitus patients had significantly more muscle palpation pain (P
