In 20 years of practice I've never seen this done. Most of the time temporomandibular disorders are a conservative musculoskeletal problem that should be managed by a properly trained physiotherapist. Needles are rarely required.
Dear Stephen M. Shaffer I agree with your opinion, but there is alternative therapy, intra articular injection of hyaluronic acid is safe, effective painless, I practice for more than 10 year with this therapy in cases ,clicking, crepitation,and lock and dislocation, I found very effective and considered as alternative to arthroscientesis of TMJ disorder.
