Paranasal sinuses are cavities within the bones of the face and skull, they are directly related to the nostrils and their function is the heating of the air that enters during the breath, also, participate in the phonation, breathing and the perception of the smell. Like other structures within the facial mass, they can present anatomical variants considered as normal and that are not related to some type of pathology or the beginning of the same ones. The objective of the present pilot study of the anatomical variants of the maxillary sinuses by cone beam tomography was to evaluate 40 beam scans were reviewed for a total of 80 maxillary sinuses. The following anatomical variants were evaluated: agenesis, hypoplasia, exostosis, pseudoseptum, pneumatization. It was found that 16 maxillary sinuses (37.2%) were male and 27 (62.8%) were female. The mean age of the patients was 43.7 years with a S.D.14.0years. Where, 55(68.8%) presented anatomic al variants. The most frequent anatomic variant was pneumatization with a total of 23 cases (41.8%), followed by a case with a total of 12 cases (21.8%). In addition, there were 8 cases (14.6%) of exostosis.
