A 9-year-old boy is brought to the emergency department after being struck in the nose by a baseball. He experienced immediate pain and a brief episode of epistaxis. His parents note that over the last several hours, he has become increasingly unable to breathe through either nostril. On physical examination, the nose appears straight, but internal speculum examination reveals a bilateral, boggy, bluish-red fluctuant swelling of the nasal septum that completely occludes the nasal passages. The swelling is tender to palpation and does not diminish with the application of topical vasoconstrictors.
Which of the following is the most appropriate next step in management?
The correct answer is:
B) Immediate incision and drainage of the swelling
This patient has a nasal septal hematoma. This is a surgical emergency because the accumulated blood separates the septal cartilage from its blood supply, the perichondrium. If the pressure is not relieved within 24–72 hours, the cartilage undergoes ischemic necrosis. The standard of care is immediate incision and drainage, followed by the placement of anterior nasal packing to prevent the re-accumulation of blood (a "dead space" management). Failure to treat this promptly can result in a septal abscess or a saddle-nose deformity, where the bridge of the nose collapses due to the loss of structural support from the cartilage.
Answer choice A: Apply a tight nasal packing and reassess in 24 hours, is incorrect. Applying packing without prior drainage would actually increase the pressure on the cartilage and accelerate necrosis.
Answer choice C: Order a non-contrast CT scan of the facial bones, is incorrect. While imaging may be used to rule out complex midface fractures, the diagnosis of a septal hematoma is purely clinical. Imaging should never delay the urgent drainage required to save the cartilage.
Answer choice D: Perform a needle aspiration for culture and sensitivity, is incorrect. While aspiration might be used for very small hematomas, a formal incision and drainage is preferred to ensure complete evacuation of the clot and to allow for the placement of a drain, if necessary.
Answer choice E: Reassure the parents and prescribe oral amoxicillin, is incorrect. Antibiotics to prevent Staphylococcus aureus abscess are often given after drainage, but they cannot treat the mechanical pressure and ischemia caused by the hematoma itself.
Key Learning Point
A septal hematoma is a medical emergency characterized by a soft, fluctuant, bluish swelling of the nasal septum following trauma. Management requires urgent incision and drainage to prevent ischemic necrosis of the septal cartilage, which can lead to a saddle-nose deformity or a septal abscess.
