Tinnitus is a condition in which the patient feels a sound in the ear without any external stimuli causing the sound. Idiopathic subjective tinnitus is highly common in adults. Mean platelet volume (MPV) is an important laboratory marker frequently used to evaluate numerous clinical conditions. This study aimed to investigate whether MPV shows a significant difference in patients with subjective tinnitus. The retrospective study included 421 patients with subjective tinnitus and 118 healthy age- and gender-matched control subjects. MPV and platelet (PLT) counts were recorded for each participant. No significant difference was observed between tinnitus patients and healthy controls concerning MPV value. Further studies are needed to investigate unknown mechanisms related to subjective tinnitus.
