Direct sagittal CT imaging of the TMJ provides several distinct advantages. Most significant is that direct imaging allows noninvasive evaluation of the disk. Direct sagittal CT scanning can confirm a clinical diagnosis of internal derangements as well as monitor splints intended for recapturing of the disk. Furthermore, the CT direct imaging allows excellent views of the bony architecture similar to those obtained with tomography. Used with clinical history and physical examination, CT can provide an excellent diagnostic modality to help provide better care for patients with internal derangement of the TMJ.
