Challenges in plain film radiographic diagnosis for the dental team

The maxillary sinus is the largest of the paranasal sinuses, with its structure and contents commonly visualised on dental radiographs. Dental practitioners are required to evaluate the entire radiograph, and it is likely there is limited exposure to maxillary sinus pathoses and radiological interpretation in the undergraduate curriculum and routine continuing professional development courses. This review covers radiological features of common benign and malignant sinus disease. Identification of normal anatomical features, common variations and pathoses can facilitate holistic patient management and potentially early detection of neoplastic disease.
