What is the BEST radiographic modality to evaluate for fascial space infections in the neck/jaw?
Show answer and explanation
Correct answer: D. CBCT (cone-beam CT) provides the best anatomical detail of fascial spaces
- A. Lateral cephalometric films show midline structures but cannot detail fascial spaces.
- B. Panoramic radiograph can show obvious swelling and dental origin but cannot accurately delineate fascial space involvement.
- C. Occlusal films are for mandible/palate — not useful for neck space infections.
- D. Correct. For evaluating FASCIAL SPACE INFECTIONS (such as lateral pharyngeal space, Ludwig's angina), CT (ideally contrast-enhanced CT, or CBCT) is the imaging modality of choice. It accurately delineates the extent of infection, identifies abscess collections, and guides surgical planning.
