anatomical variations, maxillary sinus, Haller cellsAbstract
Haller's cells are known as common anatomical variation in the region of the maxillofacial complex, located between the floor of the orbit and the roof of the maxillary sinus. This study aims to review the literature on its prevalence, observing differences in age, sex, laterality, and shape, in addition to its possible relationship with symptoms as orofacial pain, sinusitis, and nasal obstructions. The review analyzed articles published between 2018 and 2024, using panoramic radiographs and cone beam computed tomography (CBCT). The results showed large variation in prevalence (from 7% to 70%), with unilateral and bilateral forms, in addition to different morphologies. CBCT showed greater accuracy in identifying these cells. It is concluded that, although these cells are clinically relevant, further studies are needed to clarify their relationship with pathological conditions and to improve diagnostic imaging.
