Abstract
A case of a maxillary antrolith, a calcareous body found in the maxillary sinus cavity of a 38-year-old male was reported. The patient has a 3-year history of left epistaxis and headache. Three months prior to examination he developed dull pain on the left upper molar region. Although rhinoscopy revealed normal findings, a small radiopaque image was obtained at the bottom of the maxillary sinus by orthopantomography. The maxillary antrolith was removed through a gingivolabial approach. The removed antrolith was 10×9×4.5mm in size and weighed 0.3 grams. The case was compared with a case of a tooth in the maxillary sinus and maxillary osteoma in terms of radiology and surgical findings.
We analyzed 21 such cases reported in the Japanese literature and discussed the differential diagnosis of maxillary antrolith.
