Case report of a maxillary antrolith

Abstract

Introduction: Antroliths, which are pathological calcifications within the maxillary sinus, are a rare occurrence. While some may present with symptoms, most maxillary antroliths are asymptomatic incidental findings.

Presentation of case: We report a case of a 67-year-old lady with a round radiopacity within her right maxillary sinus as seen on the panoramic radiograph. Subsequent cone beam computed tomography (CBCT) scan detailed a well circumscribed radiopacity at the floor of the maxillary sinus. Surgical excision was done via Caldwell-Luc procedure.

Discussion: A review of literature was carried out with particular reference to the etiology, clinical and radiographic features and management of antroliths. Radiological examination of the sinus by standard Waters, panoramic radiograph and CT scan can aid in identification and diagnosis. While biopsy may be indicated to rule out differential diagnoses with similar presentations, in otherwise small and asymptomatic antroliths, they are generally left alone and periodic check-ups appear to be the primary choice of treatment. Surgical removal is considered the treatment of choice for antroliths with complications.

Conclusion: With regular long term follow ups, prophylactic removal of small and asymptomatic antroliths may not be necessary. However, treatment options should be presented to the patient and the ultimate decision lies with the patient with informed consent taken.
