Abstract:
OBJECTIVE:To analyze the clinical characteristics and treatment effect between bilateral (bi-) and unilateral (uni-) sudden sensorineural hearing loss (SSNHL).
METHOD:Four hundred and eighty cases of SSNHL were retrospective study, which were divided into two groups of bi-SSNHL (n = 40) and uni-SSNHL (n = 440). Clinical characteristics and treatment effects were compared of the two groups.
RESULT:The incidence rate of bi-SSNHL was 8.3 percent and uni-SSNHL was 91.7 percent of all patients with SSNHL. Bi-SSNHL occurs more commonly in patients of old age, diabetes mellitus, and lipid panes abnormalities compared to uni-SSNHL. Twenty-eight ears in the bi-SSNHL group showed hearing recovery (35%), compared with 56.4 percent of patients with uni-SSNHL.
CONCLUSION:Bi-SSNHL and uni-SSNHL may have a completely different clinical characteristics and treatment effect, that implies a different pathophysiology and prognosis. Recognition their different clinical characteristics and treatment effect between bilateral and unilateral SSNHL can help in counseling and managing the patients and correctly evaluate the prognosis.
