Overview

AP and lateral nasal bone radiographs assess nasal bone alignment and detect fractures. The AP view images the nasal bones en face while the lateral view profiles displacement. These views are used for initial trauma assessment when CT is not immediately available.

Technique

Obtain AP and lateral projections with the detector centered to the nasal bones and use appropriate exposure. Ensure minimal rotation and immobilize the head to reduce motion. Remove external nasal splints or dressings when safe to do so.

Clinical Indications

Nasal bone radiographs are indicated for trauma with suspected nasal fracture and deformity. They help detect displaced fractures and septal deviation. CT provides detailed assessment for complex facial trauma and surgical planning.

Image Assessment

Assess nasal bone continuity displacement and associated soft tissue swelling. Evaluate for septal hematoma and recommend ENT consultation when indicated. Document findings relevant to cosmetic and functional outcomes.
