Avaliação da prevalência de células de Haller e sua relação com alterações maxilofaciais

Introduction: The Haller Cells are described as aerated ethmoidal cells, located in the inferior margin of the orbit, near the ostia of the maxillary sinuses. The Cone Beam Computed Tomography (CBCT) is widely used in dentistry, allowing acquisition of images of the craniofacial region. Objective: to identify in CBCT exams the Haller´s cell relationship with the following conditions: sinus disease, bony nasal septum deviation, endodontic treatment and periapical lesions. Materials and methods: 99 CBCT exams were used, from which 51 were included in the research criteria. The images were analyzed in the Xelis Dental® software to identify the presence or absence of the Haller Cell, as well as the relationship with the mentioned conditions. Results: Among the 51 CFCT exams evaluated, 35.3% presented Haller´s Cell on the right side and 23.5% on the left side. Whereas the relationship of the Haller Cells with one or more alterations mentioned here, on the right side we had it in 72% of the cases, while on the left side such relationship was present in 75% of the cases. Conclusion: CBCT exams that present the infraorbital margin allow to verify the presence or absence of the Haller Cell. In this sample, we verified a greater presence of endodontic cases, bony nasal septum deviation and sinus disease cases in individuals who presented Haller Cells.
