Sudden sensorineural hearing loss: systemic steroid therapy and the risk of glucocorticoid-induced hyperglycemia.

Sudden sensorineural hearing loss is usually treated with systemic glucocorticoids. Intratympanic injections of glucocorticoids offer a possibly equivalent treatment alternative, avoiding adverse systemic effects on blood glucose. We, therefore, investigated the extent to which different doses of systemic glucocorticoid therapy affects blood glucose levels.
