Which are the surgical methods of tmj disc repositioning? do you need an open surgery or it can be done by arthroscopy?thank you very much.

An arthroscopic: Approach would be would be a more conservative approach and would be the preferred approach whenever possible.

Surgery: Last Resort: Surgery should only be used as a last resort TMJ treatment, except for possibly in acute trauma. Oral orthotics (night/bite guards), adjusted diet, ceasing paranormal habits, adjusting the bite, should be exhausted first. The disc can be "tied back" arthroscopically after it is mobilized ("freed up") or treated open.

Tricky: The questions on TMJ disc repositioning aren't so much how is it done, but will it last? Recurrence and relapse is the issue. Specifically, the disc can be repositioned either arthroscopically or open depending on the position/quality/adhesion of the disc and the capabilities/experience/training of the surgeon.

Depends: The specific problem and findings will dictate the treatment. Sometimes the disc is not repairable and needs to be removed and replaced. If the disc is ok, it first needs to be freed up and moved into its correct orientation. It is then secured there either by suturing, lasering, excising posterior tissue, cautery, etc. Some are done arthroscopically, some have to be done open. Key: lasts?

Either: Most often requires open surgery. A few docs try it through the scope

TMJ Disc: Especially at your age, I would try to avoid TMJ surgery until after all conservative treatment modalities fail. You need to find one or even two TMJ specialists to evaluate your situation. Many dentists call themselves "TMJ Specialists" but few really have the training and experience to help the severe or chronic cases.
