During a physical exam after a nasal bone fracture, which finding must you look for to prevent ischemic necrosis of the nasal septum?

• A. Orbital fracture
• B. Posterior epistaxis
• C. Septal hematoma
• D. Facial fracture

Answer: (C)

The main idea is recognizing a septal hematoma after nasal trauma. A hematoma that forms in the nasal septum, trapped between the mucoperichondrium and the septal cartilage, can press on the cartilage’s blood supply. This compression cuts off the nourishment the cartilage needs, so if the hematoma isn’t drained promptly, the septal cartilage can undergo ischemia and die, leading to a deformity known as a saddle nose and ongoing nasal obstruction. That’s why you should actively look for a boggy, swollen, tender septum and nasal obstruction after a nasal fracture. Urgent drainage is essential—incision and drainage of the hematoma with proper nasal packing and, when appropriate, antibiotics—to prevent necrosis. Other findings like an orbital fracture, posterior epistaxis, or a broader facial fracture don’t directly explain the risk of septal cartilage necrosis in the way a septal hematoma does, so identifying the hematoma is the critical step.
