Background: Sudden sensorineural hearing loss is an emergency condition requiring immediate diagnosis and treatment. There are several theories explaining pathogenesis of it. Some of them including vascular disease, viral infection, metabolic disease, autoimmunity, trauma and combinations of multiple factors are suggested to be the causes of it.
Purpose: This study attempted to detect correlation between dyslipidemia and occurrence of Idiopathic sudden sensorineural hearing loss.
Materials and methods: This study was a cross sectional that included patients attended to Audiology Unit in Hospital of Benha University in the period from Janurary to November 2021 and diagnosed as having SSNHL within one week, radiological and laboratory studies were done to those patients.
Results: One hundred and forty seven patients diagnosed as having idiopathic sudden sensorineural hearing loss. Forty one of them were excluded and the remaining 106 had laboratory studies (lipid profile) with results as following; 58 patients (54.7%) had increased level of total cholesterol, 61 patients (57.5%) with decreased high density lipoprotein, and 64 patients (60.3%) with elevated low density lipoprotein.
Conclusions: The study concluded that dyslipidemia represents risk factor for occurrence of sudden sensorineural hearing loss.
