Clinical role of vitamin D, vitamin B12, folate levels and hematological parameters in patients with sudden sensorineural hearing loss.

Background: Sudden sensorineural hearing loss (SSNHL), which is frequently observed in otolaryngology clinics, is characterized by sudden onset hearing loss that can develop within hours or days. Its etiology is still not fully understood.

Aims/objectives: This research aims to identify prognostic biomarkers that can be utilized to assess the progress of SSNHL as well as circumstances that may predispose individuals to the disease.
