    Abstract:
    PURPOSE: To compare short-term outcomes and procedure times for intra-articular steroid injection (IASI) to the temporomandibular joint (TMJ) with and without the use of intraoperative image guidance for patients with juvenile idiopathic arthritis (JIA). MATERIALS AND METHODS: This is a retrospective study of children with JIA who underwent TMJ IASI at Boston Children's Hospital (Boston, MA). Patients were divided into groups according to IASI technique: 1) "landmark" group if performed by an oral and maxillofacial surgeon using an anatomic landmark technique with no intraoperative image guidance or 2) "image-guided" group if performed by an interventional radiologist using intraoperative ultrasound and computed tomography. Predictor variables included IASI technique (landmark vs image guided), age, gender, JIA subtype, category of medications for arthritis, and presence of family history of autoimmune disease. Outcome variables were changes in patient-reported pain, maximal incisal opening (MIO), synovial enhancement ratio (ER), and total procedure time. RESULTS: Forty-five patients with 71 injected TMJs were included. Twenty-two patients with 36 injected TMJs were in the landmark group and 23 patients with 35 injected joints were in the image-guided group. There were no relevant differences in age, gender, family history of rheumatologic disease, or disease subtype between groups. There were no differences in resolution of pain (P = 1.00), increase in MIO (P = .975), or decrease in ER (P = .492) between groups, but procedure times averaged 49 minutes longer for the image-guided group (P < .008). CONCLUSIONS: There were no statistical differences in short-term outcomes, but procedure times were longer for the image-guided group. Although specific indications for the use of image guidance might exist, routine use of this procedure cannot be justified.
