Randomised controlled trial comparing conventional steroid treatment to conventional steroids plus hyperbaric oxygen treatment in sudden sensorineural hearing loss within two weeks of onset.
The Effectiveness of Steroids and Hyperbaric oxygen for sudden sensorineural hearing loss (SHOOSH): a randomised controlled trial.

Conditions
Summary
This trial is to determine the efficacy of HBOT in addition to steroids in the treatment of ISSHL against conventional steroids alone. There has been increasing evidence of efficacy and a recent Cochrane review suggested a large well designed RCT is needed to understand the role of HBOT. There are wide differences in clinical management across Australia due to the lack of evidence of which strategy is best. This trial hopes to bring clarity to the best management in terms of hearing outcomes.
Eligibility
Inclusion Criteria7
- Documented diagnosis of ISSHL as defined by the criteria of NIDOCD.
- Presentation within two weeks of onset of symptoms.
- Adult aged 18 or over.
- Normal hearing in contralateral ear.
- Exclusion of retro-cochlear mass.
- No contraindication to oral steroids.
- Fitness for compression in a HBOT chamber.
Exclusion Criteria4
- Contraindication to HBOT as assessed by a hyperbaric physician.
- Unstable Type 1 diabetes.
- Other causative agent for hearing loss suspected (e.g. drugs, acoustic trauma).
- History of middle ear surgery which in the ENT surgeon’s opinion would exclude the patient from being able to be pressurized.
