Hyperbaric oxygen for idiopathic sudden hearing loss: is the routine application helpful?

Conclusion: We recommend the routine application of hyperbaric oxygen (HBO) in conjunction with intravenous steroid (IVS) for all patients with idiopathic sudden sensorineural hearing loss (ISSNHL). For best results, this therapy must be started within 14 days.

Objective: To investigate the necessity of routine application of HBO therapy for ISSNHL.
