Patients with sudden sensorineural hearing loss (SSNHL) may lose their hearing. The relationship between SSNHL and total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels is still unclear. The association of TC, TG, HDL-C, and LDL-C levels with the risk and prognosis of SSNHL was explored in this study. After searching for literature in different databases, 13 researches were used to summarize the risk and prognosis of SSNHL associations with TC, TG, HDL-C, and LDL-C using meta-analysis. Total cholesterol had a significant association with the risk of SSNHL (95% CI, 1.34-2.91). Adjustment for confounding factors and grouping criteria of TG were all significant sources of heterogeneity. One of the significant sources of heterogeneity in the LDL-C subgroup analyses was an adjustment for confounders. Sensitivity analysis revealed a robust association between TC and the risk of SSNHL. There was a significant publication bias in the association between TC and SSNHL prognosis High TC level is a risk factor for SSNHL.
