Exploring Radiotherapy of Temporomandibular Joint Arthritis

September 22, 2025 updated by: Cora Waldstein, Medical University of Vienna

With this pilot study, the acute side effects and potential pain relieve after radiotherapy (RT) of the temporomandibular joint (TMJ) are prospectively recorded.

For this purpose, the symptoms of the jaw joint arthrosis/arthritis are recorded using a symptom-oriented questionnaire and the numeric rating scale for pain assessment.

Furthermore, it is examined whether the irradiation is feasible.
