What is the recommended imaging approach for assessing suspected sinus pathology related to dental disease?

• A. Panoramic radiograph for screening, followed by CBCT if detailed evaluation is required
• B. MRI is preferred for all sinus issues
• C. CT of the brain is required
• D. Periapical radiographs alone are sufficient

Answer: (A)

When imaging suspected sinus pathology from dental disease, start with a panoramic radiograph to screen the region. It provides a broad view of the maxillary dentition and the floor of the maxillary sinus, helping detect obvious disease signs and assess tooth-root relationships to the sinus in a single image. If the screen suggests sinus involvement or if detailed evaluation is needed for treatment planning, follow with cone-beam CT. CBCT offers high-resolution, 3D visualization of the sinus anatomy, ostia, mucosal changes, bone integrity, and the precise relationship between tooth roots and the sinus walls. This level of detail is essential for planning procedures or assessing the extent of disease, and it generally uses a lower radiation dose than conventional CT for targeted dental imaging. MRI isn’t the preferred initial modality for this scenario because it excels at soft tissue contrast but provides limited bone detail critical for dental-sinus pathology. CT of the brain is unnecessary for routine dental-sinus issues, and periapical radiographs alone fail to show the broader sinus involvement. The two-step approach of panoramic screening followed by CBCT when detailed evaluation is needed best balances efficiency, detail, and radiation exposure.
