title: Prognostic value of mean platelet volume on tinnitus.
abstract: 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).
  
  
  CONCLUSIONS
  The clinical findings indicated that tinnitus patients had a higher mean platelet volume than the healthy control subjects; however, the pathophysiological mechanism remains unclear.
