Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios in Pediatric Patients with Idiopathic Sudden Hearing Loss

Abstract

OBJECTIVE: We investigated the significance of the neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios, which have recently been used in adults for the prognosis of idiopathic sudden hearing loss (ISHL), in the prognosis of idiopathic sudden hearing loss in a pediatric population. MATERIALS AND METHODS: A total of 13 males and 8 females younger than19 years with idiopathic sudden hearing loss were retrospectively examined between January 2008 and August 2016.The control group consisted of 12 healthy males and 12 healthy females. Patients were divided into two groups: those who recovered after treatment and those who did not. RESULTS: A statistical significance for the neutrophil-to-lymphocyte ratio was detected between the patient group and control group and between patients who recovered and those who did not (p<0.05). No statistical significance for the platelet-to-lymphocyte ratio was detected between the patient group and control group and between patients with recovery and those without recovery (p>0.05). CONCLUSION: The neutrophil-to-lymphocyte ratio is an important marker for the prognosis of idiopathic sudden hearing loss in pediatric patients, similar to its use in adult patients.
