Anatomical Variation of the Maxillary Sinus in Cone Beam Computed Tomography

الملخص EN

Purpose.

The aim of this paper is to report a case in which the cone beam computed tomography (CBCT) was important for the confirmation of the presence of maxillary sinus septum and, therefore, the absence of a suspected pathologic process.

Case Description.

A 27-year-old male patient was referred for the assessment of a panoramic radiograph displaying a radiolucent area with radiopaque border located in the apical region of the left upper premolars.

The provisional diagnosis was either anatomical variation of the maxillary sinuses or a bony lesion.

Conclusion.

The CBCT was important for an accurate assessment and further confirmation of the presence of maxillary septum, avoiding unnecessary surgical explorations.
