Management of Nasal Barotrauma
For nasal/sinus barotrauma, initiate treatment with oral decongestants, topical nasal decongestants (limited to 3-5 days), and topical nasal steroids, with oral steroids added for moderate-to-severe cases; reserve functional endoscopic sinus surgery (FESS) for refractory cases that fail conservative management.
Initial Conservative Management (First-Line)
Start all patients with the following regimen immediately:
- Oral decongestants (pseudoephedrine 120 mg) - proven effective in adults for pressure equalization 1
- Topical nasal decongestants (xylometazoline spray) - superior to oral decongestants for mucosal decongestion, but limit use to 3-5 consecutive days maximum to prevent rebound congestion 2
- Topical nasal corticosteroids (mometasone or fluticasone at maximal dosage) - continue for 6 weeks 3
- Analgesics (acetaminophen) for pain control 4
- Nasal saline irrigation with large-volume hypertonic (3-5%) saline - improves symptoms better than isotonic, though causes more nasal irritation 2. Use only micron-filtered, boiled, or distilled water 2
Oral Corticosteroids for Moderate-Severe Cases
Add a tapering course of oral steroids for patients with significant symptoms 5, 6. The evidence shows:
- 63.6% success rate with oral steroids in barosinusitis 6
- Modest benefit when combined with other therapies 2
- Use a 5-day to 1-week course 3, 5
Adjunctive Therapy Based on Underlying Conditions
Add antihistamines ONLY if allergic rhinitis is present - they worsen symptoms in non-allergic patients by drying nasal mucosa 2. The case report demonstrates that undiagnosed allergic rhinitis significantly increases barotrauma risk, and proper AR management prevented recurrence 4.
Add antibiotics ONLY if bacterial sinusitis initiated the episode - not routinely indicated 5.
Expected Timeline for Resolution
Most cases resolve with conservative management:
- Stage I-II barotrauma: Treat conservatively for 1 week 5
- Submucosal hemorrhages in affected sinuses spontaneously resolve within 1 year 4
- Follow-up imaging at 2 weeks, 1 month, and 1 year shows progressive resolution 4
Surgical Intervention for Refractory Cases
FESS is indicated when conservative treatment fails after 6 weeks 3. The surgical success rate is excellent:
- 91.5% success rate for FESS in refractory barosinusitis 6
- 35 of 40 divers (87.5%) successfully resumed activities after treatment (medical or surgical) 3
- No significant long-term hazards for future pressure exposure 3
Adjunctive procedures may include middle meatal antrostomy, maxillary antrostomy (20.7%), septoplasty (15.5%), or turbinate surgery (9.1%) based on anatomic findings 6.
Critical Pitfalls to Avoid
- Do not use topical decongestants beyond 5 days - causes rhinitis medicamentosa (rebound congestion) 2
- Do not use antihistamines in non-allergic patients - worsens congestion 2
- Do not use contaminated water for nasal irrigation - risk of Naegleria fowleri infection 2
- Do not delay diagnosis of underlying sinonasal pathology - undiagnosed allergic rhinitis or chronic rhinosinusitis dramatically increases recurrence risk 4, 3
Prevention for Future Pressure Exposure
Before flying or diving after barotrauma:
- Ensure complete resolution of symptoms
- Optimize management of any underlying allergic rhinitis or chronic rhinosinusitis 4
- Consider prophylactic oral decongestant before flight and nasal decongestant spray just prior to descent 5
- Wait minimum 1 week after most interventions, longer if surgical treatment was required 7
