A 22-year-old man is brought to the emergency department after being struck in the face with a basketball two hours ago. He reports significant pain, a nosebleed that has since stopped, and difficulty breathing through his nose. Past medical history is negative. Vital signs are within normal limits. On physical examination, there is marked swelling and ecchymosis over the nasal bridge. The nose appears slightly deviated to the right. Palpation reveals crepitus and point tenderness over the nasal bones. Speculum examination shows no humps or fluctuant masses on the nasal septum. He is able to move his eyes in all directions without double vision, and his dental occlusion is normal.
Which of the following is the most appropriate next step in management?
The correct answer is:
B) Observation and follow-up in 3 to 7 days
The nasal bone is the most commonly fractured bone in the face. The diagnosis is primarily clinical, based on the history of trauma, presence of swelling, deformity, crepitus, and tenderness. In the acute setting, significant soft tissue swelling often obscures the underlying bony alignment, making immediate reduction difficult and inaccurate. The standard of care for a simple nasal fracture is to allow the swelling to subside and re-evaluate the patient in 3 to 7 days. If a significant cosmetic or functional deformity persists once the swelling is gone, a closed reduction can be performed within a 1- to 2-week window before the bones begin to malunite.
Answer choice A: Immediate closed reduction under local anesthesia, is incorrect. Immediate reduction is generally avoided unless the patient presents within the first hour before swelling has peaked, or if there is a severe, gross deformity that is easily correctable.
Answer choice C: Plain film X-ray of the nasal bones, is incorrect. Plain X-rays are not recommended for isolated nasal fractures. They have low sensitivity and specificity, and the management is dictated by clinical appearance and breathing function, not by the presence of a fracture line on film.
Answer choice D: Urgent CT scan of the facial bones, is incorrect. A CT scan is not indicated for an isolated nasal fracture. It should be reserved for cases where there is suspicion of more complex injuries, such as orbital floor fractures (look for diplopia or limited upward gaze) or Le Fort fractures (look for malocclusion).
Answer choice E: Urgent needle aspiration of the nasal bridge, is incorrect. Needle aspiration is not a standard treatment. However, it is vital to distinguish the fracture in this case from the management of a septal hematoma, which requires immediate incision and drainage.
Key Learning Point
The diagnosis of a nasal bone fracture primarily clinical, based on the history of trauma, presence of swelling, deformity, crepitus, and tenderness. In the acute setting, significant soft tissue swelling often obscures the underlying bony alignment, making immediate reduction difficult and inaccurate. The standard of care for a simple nasal fracture is to allow the swelling to subside and re-evaluate the patient in 3 to 7 days. The most critical part of the physical exam for a nasal fracture is the internal speculum exam to rule out a septal hematoma. A septal hematoma appears as a dark red or bluish, fluctuant swelling on the nasal septum. If left untreated, it can lead to pressure necrosis of the septal cartilage, resulting in a saddle-nose deformity or septal abscess.
