[Evidence-based treatment of idiopathic sudden sensorineural hearing loss].

Idiopathic sudden sensorineural hearing loss is a condition, in which an idiopathic rapid unilateral decline in hearing thresholds is seen. In this review, the latest research is summarised. In Denmark, the traditional treatment is systemic steroids (SST), but new research reveals, that the use of SST lacks evidence. There is significant evidence for the use of intratympanic steroid injections (ITSI) as salvage treatment. The use of ITSI as first-line treatment, as well as combined with SST, is found to be of equal effect as SST alone. A national Danish clinical guideline is needed.
