After an elbow strike to one side of the nose during water polo causing unilateral epistaxis, localized swelling, slowed bleeding, and no tenderness on bony palpation, what concerning complications should be evaluated?

Immediate Concerns After Nasal Trauma

You need to rule out a nasal septal hematoma immediately—this is the most critical concern that can lead to permanent cartilage damage and septal perforation if missed. 1

Key Red Flags to Assess Now

Even though the bleeding has slowed and there's no bony tenderness, several concerning complications require evaluation:

1. Septal Hematoma (Most Urgent)

• Examine the nasal septum internally for a boggy, bluish swelling on either side
• This appears as a soft, fluctuant mass obstructing the nasal passage
• Must be drained within 24 hours to prevent cartilage necrosis and permanent deformity 1
• The absence of bony tenderness does NOT rule this out—it's a soft tissue injury

2. Unilateral Epistaxis Requiring Further Investigation

The fact that bleeding is from one side only is significant. According to guidelines, recurrent unilateral nasal bleeding warrants nasal endoscopy to exclude underlying pathology 2. While this is your first episode, the unilateral nature combined with trauma history means you should:

• Monitor for rebleeding over the next 24-48 hours
• Seek ENT evaluation if bleeding recurs
• Be aware that nasal masses, though rare, can present with unilateral epistaxis (55% of nasal malignancies present this way) 2

3. Warning Signs Requiring Immediate Medical Attention

Seek emergency care if you develop any of these symptoms 2:

• Vision changes (could indicate orbital involvement or vascular injury)
• Fever over 101°F (infection risk)
• Increasing pain (expanding hematoma or infection)
• Swelling of the face (spreading infection or vascular injury)
• Shortness of breath or labored breathing
• Loss of color around the skin of the nose (tissue ischemia)
• Return of significant bleeding that doesn't stop with 15 minutes of direct pressure

4. Rare but Serious: Vascular Injury

Though uncommon, facial trauma can cause pseudoaneurysm of the internal carotid artery, which can present with recurrent severe epistaxis even months after injury 3. This is more relevant if you develop:

• Recurrent severe bleeding episodes
• Massive blood loss (>500-1000ml)
• Associated neurological symptoms

Immediate Management Steps

Right now, you should:

1. Perform or have someone perform an internal nasal examination to look for septal hematoma—this cannot wait
2. Apply direct pressure by pinching the soft part of your nose for a full 15 minutes if bleeding continues 2
3. Use oxymetazoline or phenylephrine nasal spray (2 sprays in the bleeding nostril) after clearing clots, then hold pressure for 5 more minutes 2
4. Avoid nose blowing, strenuous activity, heavy lifting, bending over, and straining for at least one week 2
5. Use acetaminophen for pain—avoid aspirin and ibuprofen as they increase bleeding risk 2
6. Sleep with head elevated to reduce nasal blood flow 2

When to Get Imaging

CT maxillofacial without IV contrast is the appropriate imaging if you develop 4:

• Visible or palpable nasal deformity
• Persistent tenderness
• Recurrent bleeding
• Any of the warning signs above

The absence of bony tenderness on external palpation is reassuring but doesn't exclude cartilaginous injury or septal hematoma, which are soft tissue injuries.

Follow-Up Care

You should be evaluated by a clinician within 24-48 hours even if symptoms seem minor, specifically to:

• Rule out septal hematoma through internal examination
• Assess for any delayed complications
• Receive proper wound care instructions
• Document the injury for potential delayed complications

Common pitfall: Many nasal injuries are underdiagnosed because internal examination is not performed 5, 6. The external appearance and lack of bony tenderness can be falsely reassuring while a septal hematoma develops internally.
