The goal of this clinical trial is to evaluate the long-term outcome of surgical intervention (arthroscopy or discectomy) due to the diagnoses temporomandibular joint disc displacement with or without displacement. The main questions it aims to answer are:
* Does the surgical outcome recorded at the earlier 6-month follow up persist at the long-term follow up approximately 10 years postoperatively? * How does the radiologically determined degree of joint degeneration change with time in patients that have had joint surgery? Researchers will compare the six-month surgical outcome to the ten-year outcome to see if temporomandibular joint surgery results are stable over time.
Participants with an earlier performed joint surgery will:
* Have a clinical examination approximately ten years postoperatively. * Have a temporomandibular joint x-ray scan performed (cone-beam computed tomography).
