Steroids comprise the mainstay of treatment for idiopathic sudden sensorineural hearing loss (ISSNHL).

Since steroidal treatment was integrated to clinical practice guidelines, newly published no-treatment or placebo arms in clinical trials are scarce.

We evaluated the effectiveness of steroidal treatment ± hyperbaric oxygen therapy, the data should be compared to spontaneous recovery.

The aim of this paper is to find the most accurate spontaneous recovery rate, in the light of which, other treatment modalities should be judged.

Eligible studies published until July 2021 were identified through systematic searches of ‘PubMed’, ‘Web of Science’ and ‘Google Scholar’.

Retrospective studies and randomised/non-randomised control trials involving only adult participants (≥18 years) with ISSNHL, and placebo/no treatment were included.

Only articles that used the American Academy of Otolaryngology–Head and Neck Surgery's diagnostic criteria for ISSNHL were included.
