A case of odontogenic maxillary sinusitis with many calculi

We report a case of odontogenic maxillary sinusitis with many calculi. The patient was 37-yearold woman who was introduced to our department for treatment of a calcified mass in the right maxillary sinus. Maxillary sinusectomy was performed with the patient under general anesthesia. A total of 55 stones (∅1-5mm) were found in the maxillary sinus. Histopathological study revealed maxillary sinusitis with some fine sequestra in the membrane. Most of the stones had several sequestra as nuclei.
