A panoramic radiograph (Figure 1) and CT examination (Figure 2) were requested to assess the area, and the images showed a severe marginal alveolar bone loss in the area of the missing upper right posterior teeth and inferior extension of the maxillary sinus floor.
CT examination of the right maxilla in the bone window: (a) axial section, (b) corrected sagittal section, (c) coronal section, and (d) surface rendering; white arrows showing a small, well-defined, corticated, spherical, radiolucency in the superioanterior wall of the right maxillary sinus wall just below the infraorbital rim and medial to the infraorbital foramen.

It measured about 3 to 4 mm in dimension and was distinct from the surrounding normal bone (Figure 3(a)). The right infraorbital nerve was protected and not violated (Figure 3(b)).
