Abstract
A healthy,12-year-old female patient, presented with an anterior open bite requesting orthodontic treatment. A panoramic radiograph was requested for treatment planning (Figure 1). An incidental finding of well-defined multilocular radiolucencies were detected superimposed over the right ramus and middle cranial fossa region. The patient was asymptomatic with no clinical signs of facial asymmetry. A cone-beam computerised tomography (CBCT) scan was requested to exclude any occult pathology (Figure 2).
Highlights
The cone-beam computerised tomography (CBCT) images showed multiple air-filled spaces that are continuous with the mastoid air cells, affecting the temporal and sphenoidal bones (Figure 2 A-D)
The airspaces were limited to the right side and were associated with areas of mild expansion, best visualised in the lateral and medial pterygoid plates (Figure 2C)
The aetiology is due to a combination of congenital and environmental factors, including increased pressure within the middle ear.[3]. These entities are often asymptomatic with infrequent reports of tinnitus or headaches
Summary
The CBCT images showed multiple air-filled spaces that are continuous with the mastoid air cells, affecting the temporal and sphenoidal bones (Figure 2 A-D). The airspaces were limited to the right side and were associated with areas of mild expansion, best visualised in the lateral and medial pterygoid plates (Figure 2C).
