Abstract

The thickness of the roof of the glenoid fossa (RGF) is highly variable, but there are no reported cases of absence of mineralized bone at the RGF in an asymptomatic patient. We present the rare finding of a large apparent discontinuity of the RGF discovered incidentally on cone-beam computed tomography (CBCT) images of an asymptomatic temporomandibular joint in a 22-year-old female, which was proven to be a normal joint on magnetic resonance images. The apparent discontinuity of the RGF in this case, considered in the light of known measurements of the RGF, may actually represent very thin bone that could not be visualized because of the relatively large CBCT voxel size. A review of the published literature revealed no clinical significance of a thin RGF.
