Exostosis with cysts in the maxillary sinus is extremely rare. We report two cases of exosotosis with cysts in the maxillary sinus. One patient was a 42-year-old woman who was referred to our hospital because of a radiopaque lesion in the right maxillary sinus. Computed tomography showed a high density oval mass with a low density round lesion containing the roots of the right maxillary first and second molars in the maxillary sinus. The mass, measuring 25 × 15 × 15 mm, and soft tissue lesion were removed surgically via the carine fossa under general anesthesia. The histopathological diagnosis was exostosis with a mucous cyst of the maxillary sinus. The other patient was a 29-year-old woman who was referred to our hospital because of gingival swelling and pain of the right upper third molar. Computed tomography showed a high density oval mass with a cystic lesion containing the right maxillary third molar in the right maxillary sinus. The mass, measuring 30 × 23 × 15 mm, and the cyst were removed surgically via the carine fossa under general anesthesia. The histopathological diagnosis was exostosis with a dentigerous cyst.
