Introduction: Sudden sensorineural hearing loss (SSNHL) is an emergency case that requires immediate and comprehensive management. This condition can be caused by Streptococcus suis bacterial meningitis. Complete blood counts (CBC) examinations are often carried out in SSNHL patients that caused by infection. Some CBC components can be clinical indicators of the severity and prognosis of SSNHL. Objective: To find out the differences in CBC among S. suis bacterial meningitis patients with SSNHL and S. suis bacterial meningitis patients with normal hearing at Prof. Dr. I.G.N.G. Ngoerah Hospital Denpasar from January 2019 – May 2023. Methods: This study used an analytical research design using a retrospective case control method to compare CBC results (hematocrit, NLR, PLR, MLR, RDW and MPV) in 40 cases patients with SSNHL due to S. suis bacterial meningitis and 40 controls patients with S. suis bacterial meningitis patients with normal hearing. Result: In this study, it was found that there is no significant difference between case group compared to control group in terms of CBC results. The mean hematocrit value was 40.67 (± 4.45) in cases and 40.87 (± 4.08) in controls, with p-value 0.842. The mean MPV value was 9.82 (± 1.58) in cases and 9.33 (± 1.78) in controls, with p-value 0.200. The mean NLR value in the case group was 24.46, while in the control group it was 28.79, with p-value 0.124. The mean PLR value in the case group was 200.01, while in the control group it was 247.80, with p-value 0.126. The mean MLR value was 1.33 in cases and 1.19 in controls, with p-value 0.303. The mean RDW value was 12.98 in cases and 12.81 in controls, with p-value 0.950. Conclusion: From 40 people suffering SSNHL due to S. suis bacterial meningitis it was found that most of research subjects are men (75%) and the average age of subjects is 53 years. This study found that there were no significant differences between the results of mean hematocrit, NLR, PLR, MLR, RDW and MPV in patients with SSNHL due to S. suis bacterial meningitis compared to controls.
