Abstract
INTRODUCTION: The aetiology, management and prognosis of idiopathic Sdden Sensorineural Hearing Loss (ISSNHL) are still uncertain despite adequate investigation. OBJECTIVE: We conducted the present study to investigate the possible relationship between the neutrophil-to-lymphocyte ratio (NLR) and the prognosis of ISSNHL based on PSM. METHODS: This was a retrospective observational study. Data and statistical analyses were performed using the SPSS statistical program (SPSS 19.0). PSM was performed using STATA (15.0). RESULTS: NLR = 3.42 was the cut-off value. After PSM, 84 pairs of patients were successfully matched. The number of patients in the effective group with the NLR < 3.42 and NLR < 3.42 were significantly different (P < 0.001). CONCLUSION: The NLR is an inexpensive and reliable index to predict the ISSNHL. We hold the view that the NLR can be a reliable factor for clinical doctors to predict the prognosis in ISSNHL. To further prove that the NLR is a powerful prognostic factor in ISSNHL, larger prospective studies are required in the future.
