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

• A. Panoramic radiograph for screening, followed by CBCT if detailed evaluation is required
• B. CBCT for screening, followed by panoramic if needed
• C. MRI as initial study
• D. Periapical radiographs only

Answer: (A)

Screening with a panoramic radiograph covers both the teeth and the maxillary sinus in one exam, making it the sensible first step when dental disease could be contributing to sinus symptoms. It’s efficient, widely available, inexpensive, and delivers a broad view to spot obvious dental sources of infection or gross sinus involvement that might explain the patient’s signs. If the panoramic raises concerns or if a precise assessment is needed for diagnosis or treatment planning, cone-beam CT provides detailed three-dimensional information about bone and sinus anatomy. CBCT can show the exact relationship between a tooth, its root, and the sinus floor, the extent of any bony destruction, ostiomeatal complexity, mucosal thickening, and any open communication with the dental roots—information that guides surgical or endodontic decisions and reduces surprises during intervention. MRI isn’t used initially here because the priority is hard-tissue and dental-sinus relationships, and it’s less practical for identifying bony changes and dental sources. Periapical radiographs alone don’t give the full sinus view and can miss sinus pathology, so they aren’t sufficient as the sole imaging approach for suspected sinus involvement related to dental disease. So the recommended approach is: start with a panoramic radiograph for screening, then use CBCT for detailed evaluation if needed.
