Contact a study team

Contact the TINNITOX study for tinnitus with jaw clenching or jaw pain (Norway)

Read the EU trial record, open 'Locations and contact points', and contact the listed public study contact for Norway. Ask whether TINNITOX may be relevant if you have tinnitus with bruxism or jaw-muscle pain and whether a referral is needed.

Before you go

Available in: Norway
Time now: 5 minutes or less
Cost: No payment required
Commitment afterwards: An enquiry takes a few minutes. The published participant description involves eight visits over a year, including injection and control visits; placebo is part of the study. Ask the research team to confirm the current protocol, eligibility and costs.

Important to know. The EU record lists adult patients in Norway and the live status 'Authorised, recruiting'. The study concerns tinnitus with bruxism and/or jaw-muscle myalgia, with further medical exclusions. It requires visits to Sørlandsklinikken in Arendal. Botulinum toxin is being investigated here; an established tinnitus benefit is not claimed. Only the study team can assess eligibility and explain risks, costs and consent. An enquiry is not enrolment, and no personal benefit is promised. Tinnitus Action is independent and does not receive your enquiry or health information.

What you do: Ask the study team whether you might be suitable.
Where it happens: In the official EU Clinical Trials register. Open “Locations and contact points” to find the public contact for Norway.
When it counts: When you have sent your enquiry. It does not mean you are taking part; the study team decides.

About this opportunity

Purpose: TINNITOX is a blinded, placebo-controlled study testing botulinum-toxin injections into jaw muscles for tinnitus associated with bruxism or jaw-muscle pain.
