The <jats:styled-content style=\"fixed-case\">CBCT<\/jats:styled-content> exams were independently evaluated by two oral and maxillofacial radiologists who assessed the presence of anatomic variations and lesions of the maxillary sinus. As most of the <jats:styled-content style=\"fixed-case\">CBCT<\/jats:styled-content> exams did not allow the evaluation of the area close to the maxillary sinus roof, anatomic variations that take place at this site were not assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The anatomic variations detected were pneumatization (83.2%), antral septa (44.4%), hypoplasia (4.8%), and exostosis (2.6%). The identified lesions were mucosal thickening (\u22643\u00a0mm in 54.8% and &gt;3\u00a0mm in 62.6%), polypoid lesions (21.4%), discontinuity of the sinus floor (17.4%), air\u2010fluid level (4.4%), bone thickening of the maxillary sinus wall (3.8%), antroliths (3.2%), discontinuity of the sinus lateral wall (2.6%), sinus opacification (1.8%), and foreign body (1.6%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Anatomic variations and lesions of the maxillary sinus were common findings in <jats:styled-content style=\"fixed-case\">CBCT<\/jats:styled-content> exams of the maxilla required for dental implant planning. As some of these conditions can modify dental implant planning and must require specialized treatment, its recognition is noteworthy in dental practice, and especially in implantology.
