Prognostic value of mean platelet volume on tinnitus.

Objective: This study aimed to determine whether there was any relationship between tinnitus and mean platelet volume.

Methods: This retrospective study was conducted between January 2013 and January 2014 in Ankara Atatürk Hospital and Ondokuz Mayıs University Hospital, Turkey, on a study group of 86 patients with tinnitus and a control group of 84 healthy subjects. Mean platelet volume was recorded and comparisons were made between the two groups.

Results: Mean (± standard deviation) platelet volume was 7.67 ± 0.83 μm(3) in the study group and 7.28 ± 0.56 μm(3) in the control group. There was a statistically significant difference in mean platelet volume between the tinnitus patients and the healthy subjects (p < 0.05).

Conclusion: The clinical findings indicated that tinnitus patients had a higher mean platelet volume than the healthy control subjects; however, the pathophysiological mechanism remains unclear.
