Radiographic appearance of the maxillary sinuses in health and disease

The maxillary sinuses are frequently seen on intra-oral and panoramic radiographs taken in general dental practice. Variation in normal appearances of the maxillary sinuses can be mistaken for disease and a wide range of odontogenic and non-odontogenic diseases can change sinus appearance. This means that a systematic approach is needed when interpreting radiographs, including those of the sinuses. The article provides examples of normal anatomy and illustrations of some of the more common abnormal findings, as well as suggestions for management in these cases. CPD/Clinical Relevance: The maxillary sinuses are visible on radiographs in general dental practice, meaning that practitioners need to be able to recognize features of health and disease in them.
