Objective: This study aimed to analyze the therapeutic effect of Ginkgo biloba extract (EGb 761) on sudden sensorineural hearing loss (SSNHL) and its influence on hemorheology. Methods: The clinical data of patients diagnosed with SSNHL and admitted to the Wendeng Hospital of Traditional Chinese Orthopedics and Traumatology of Shandong Province from May 2020 to May 2023 were retrospectively analyzed. Based on different clinical treatment protocols, patients were divided into a control group (treated with routine treatment) and an administration group (treated with routine treatment + EGb 761). Both groups underwent drug treatment for 10 days. Subsequently, the hearing threshold, hemorheological parameters (blood high shear viscosity, blood low shear viscosity, plasma viscosity, and platelet aggregation rate) and inflammatory factors and serum levels (C-reactive protein, interleukin-6, tumor necrosis factor-α and soluble vascular cell adhesion molecule-1) of these groups were compared. Results: This study comprised 120 patients, with 66 cases in the control group and 54 cases in the administration group. Following treatment, the total effective rate of the administration group was significantly higher than that of the control group (90.74% vs. 72.73%) ( P -value < 0.05). The hearing threshold, hemorheological parameters, inflammatory factors, and serum levels were significantly lower in the administration group than in the control group ( P -value < 0.05). Conclusions: Compared with routine treatment, joint EGb 761 in the SSNHL treatment may improve the hearing threshold and hemorheological indexes of patients, inhibit the inflammatory response, and promote the recovery of hearing function. Moreover, no serious adverse reactions are observed, indicating adequate safety.
