Correlation analysis between hearing curve type and dyslipidemia in sudden sensorineural hearing loss

Objective To analyze the characteristics of blood lipid metabolism in patients with sudden sensorineural hearing loss (SSNHL), and to explore the relationships between the incidence and therapeutic effect and hearing curve type in SSNHL. Methods Clinical data of 385 cases with SSNHL treated in our department from Jan 2012 to July 2019 were analyzed retrospectively to observe the correlations between patients'' age, type of hearing curve, curative effect and blood lipid. Results A total of 385 cases were collected, including 163 males and 222 females. They ranged in age from 12 to 85 years with an average age of 46. Compared with the patients with hearing curve of low-frequency and high-frequency descending types, the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C) of those with flat descending type and total deafness were increased, and the levels of high density lipoprotein (HDL-C) were decreased. The levels of TC and LDL-C in 40~69 age group were higher than those in 10~39 group, and the differences were statistically significant (P>0.05). As for the hearing curve, the rates of total deafness type of the 40~69 age group and 10~39 age group were 39.9% and 32.8%, and those of the flat descending type were 51.2% and 47.4%. There were no significant differences in levels of TC, TG, HDL-C and LDL-C among the patients with different therapeutic effects. Conclusions The pathogenesis of SSNHL with different types of hearing curve may be different. Blood lipids may play an important role in the pathogenesis of SSNHL in patients with flat descending curve and total deafness through the mechanism of increasing blood viscosity and vascular endothelial cell damage.
