Sudden sensorineural hearing loss (SSNHL) is defined as the sudden onset of unilateral sensorineural hearing loss of ≥30 dB over at least three contiguous audiometric frequencies (1). Diabetes is a risk factor of SSNHL, possibly due to microangiopathy (2). Currently, the clinical studies of SSNHL rarely focus on diabetic patients. The correlations between biochemical data and hearing outcomes in SSNHL are seldom analyzed. We analyzed the characteristics of SSNHL in diabetic patients and tried to elucidate the possible prognostic factors.
Medical charts of diabetic patients admitted for SSNHL from 1984 to 2003 were retrospectively reviewed. A total of 67 patients (38 men and 29 women) with a mean …
