A retrospective study of tinnitus sufferers who had completed suicide was done. A questionnaire was compiled & circulated world-wide. Adequate information was obtained for 28 cases. An association between suicide & left-sided tinnitus reported previously, was not conclusively replicated. In fact, no particular tinnitus parameter, or associated audiological symptoms was over-represented in the suicide series. Demographically, tinnitus suicide victims were characterized by being male, elderly, & socially isolated. There was a high prevalence of psychiatric morbidity, in particular depression. A suicide attempt within the year preceding suicide was noted in 5 individuals. (12 refs.)
