No results posted yet for this study

Summary

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).

Conditions

  • Temporomandibular Disorders (TMD)
  • Temporomandibular Joint Disc Displacement, With Reduction
  • Temporomandibular Joint Disc Displacement, Without Reduction

Interventions

PROCEDURE

Arthroscopy & saline irrigation alone

Arthroscopic lysis and lavage refers to an arthroscopic procedure where the temporomandibular joint is rinsed with saline solution and where the joint capsule is distended and where adhesions are lysated bluntly

PROCEDURE

Discectomy

Discectomy refers to open temporomandibular joint surgery where the joint disc is completely removed without being replaced.
