Objective: This study aimed to investigate the prognostic value of systemic immune inflammation index (SII) in sudden idiopathic sensorineural hearing loss (SISNHL). Methods: Eighty-nine patients diagnosed with SISNHL were included in this study. SII was calculated from the complete blood count when the patients were hospitalised. The patients were treated in accordance with our routine SISNHL protocol. Hearing recovery was evaluated in accordance with Siegel’s criteria, and two main groups were created (complete and incomplete recovery groups). The control group consisted of patients who were admitted to our clinic for hearing examination. SIIs were statistically analysed amongst these three groups (control, complete recovery and incomplete recovery groups). Results: The mean SII of the three groups significantly differed (p= 0.002). The control group significantly differed from the two other groups (complete recovery group: p= 0.023, incomplete recovery group: p= 0.048). The complete recovery group did not significantly differ from the incomplete recovery group (p= 0.950). Conclusion: SII had no prognostic value in patients diagnosed with SISNHL. However, SIIs were significantly higher in the patient groups diagnosed with SISNHL than those in the control group. This finding supports the predictive value of SII in SISNHL. Studies with more participants are needed to demonstrate the predictive value of SII in SISNHL.
