Abstract
Temporomandibular Joint (TMJ) involvement in patients with ulcerative colitis (UC) is a rare manifestation. To the best of our knowledge there are only two cases in the literature reported the presence of TMJ involvement in a patient with UC. We report a case of 23-year-old female with a two-year history of UC she was complaining of unilateral temporomandibular jaw pain, the pain was severe enough to affect her daily activities, she was not able to speak and there was a limitation of mouth opening. The patient was only able to open her mouth for 2.5 cm. C-reactive protein and erythrocyte sedimentation rate were high, rheumatoid factor was negative. The computed tomography (CT) of the mandible and teeth reveals flattening with erosion of the condylar process of the left mandibular joint without the presence of joint effusion or soft tissue swelling. Our patient was managed by biological treatment Ustekinumab for 6 months, as a result the patient improved and she was able to open her mouth up to 4 cm. Clinicians should be aware of the importance of biological treatment in these circumstances, TMJ arthritis in UC patients is considered a rare and unusual picture of extraintesinal IBD manfistations.
