Abstract

Objective:

To determine the relationship between severe tinnitus and inflammation using the neutrophil-to-lymphocyte ratio as a marker of stress.

Methods:

A total of 107 patients who had been suffering with severe tinnitus (tinnitus handicap inventory scale grades of 3–5) for at least 2 weeks were recruited. Patients underwent detailed ENT examinations and audiometric tests to exclude a relevant pathological cause of the tinnitus. Patients with systemic diseases, malignancy or inflammatory diseases that could alter neutrophil-to-lymphocyte ratio were excluded. A total of 107 age- and sex-matched healthy control participants were also recruited. Routine laboratory test results and neutrophil-to-lymphocyte ratio were compared between the patients and controls.

Results:

Lipid profile, liver function, white blood cell count, haemoglobin level, mean corpuscular volume, and vitamin B12 and folate levels were similar among the patients and controls. However, mean neutrophil-to-lymphocyte ratio was significantly higher among the patients than the controls (p < 0.05).

Conclusion:

The findings of this novel study suggest that neutrophil-to-lymphocyte ratio should be considered during the evaluation of tinnitus patients as a potential clinical marker of tinnitus. Further studies are required to verify the findings.
