The use of SPECT in the assessment of post-traumatic changes in the temporomandibular joint has been infrequent, as
compared with other radiographic techniques. SPECT have the potential to detect active bone remodeling whereas
corresponding radiographs may be normal or document past structural change in the joint. Thorough examination of
TMJ especially after trauma saves the paiieni from neglected treatment and further complications. This study was
conducted on 24 joints of 12 adult patients (10 males, 2 females), who undergone 3dimensional computerized
tomography (3D-CT) to confirm and define the location and direction of the fractured segments then they were.
send for treatment. After one yean-they were sent to do MRI and SPECT examination. The results of this study revealed
high percentage (66.6) of displaced discs at the traumatized joints, also a considerable percentage of displaced discs in
the unaffected joints. Small percentage (8.3) of the affected joints showed disc deformities. (91.6) of affected joints
examined by SPECT were positive and gave high ratios of uptake, although 3 joints showed normal position and
morphology on MR images. A considerable percentage (58.3) of unaffected joints gave positive results on SPECT.
Similarly five joints of them were normal on MRI. Sensitivity and specificity of SPECT was 83 and 58 respectively.
There was a statistical significance difference regarding count ratio of the affected and unaffected joints (P < 0.05). It
was concluded that 3D-CT technique produced im;.ges that allowed an improvement in the visualization of affected
structures. The clinician should noi rely on results of MRI alone specially if they do not correlate with clinical
symptoms, but should consider another confirmatory technique which is more sensitive for detecting and staging
osseous diseases of the TMJ related to disc dysfunction. SPECT can detect altered joint mechanics that are not evident at
functionally anatomic MR imaging.
