Abstract

Single photon emission computed tomographic(SPECT) imaging, performed at oral and maxillofacial surgery department, is valuable in assessing temporomandibular dysfunction, looking for metastases in patients with malignancies, diagnosing facial asymmetry. Conventional planar scintigraphy is limited by two-dimensional representation of three-dimensional structures. The SPECT exam, by sectioning through a distribution of tracer, eliminates the obscuring effects of tracer located outside the plane of interest. In our department, we used this image for four type cases retrospectively. 1. Those patients who have facial asymmetry 2. To find metastases in patients with malignacies 3. In combination with magnetic resonance imagine, to confirm the diagnosis of internal joint derangement 4. To evaluate the viability of grafted bone. Recently, this image is able to be used in those patients whose symptoms etiology cannot be explained by other diagnostic techniques.
