How are sinus problems managed?

Management of Sinus Problems

The management of sinus problems should follow a stepwise approach, beginning with intranasal corticosteroids, saline irrigation, and appropriate antibiotics for bacterial infections, with surgical intervention reserved for cases that fail maximal medical therapy. 1

Diagnosis

Clinical Presentation

• Key symptoms:
  • Acute sinusitis: nasal congestion, purulent rhinorrhea, facial pain/pressure, post-nasal drainage, headache, cough 2
  • Chronic sinusitis: similar symptoms but more subtle, with less prominent pain 2
  • Decreased sense of smell in chronic cases 1

Physical Examination

• Look for:
  • Mucosal erythema and purulent nasal secretions
  • Sinus tenderness on palpation
  • Periorbital edema
  • Pharyngeal erythema 2, 1

Diagnostic Testing

• CT imaging is the technique of choice to confirm sinusitis when:
  • Symptoms are vague
  • Physical findings are equivocal
  • Disease persists despite optimal therapy 2
• Nasal endoscopy should be performed to confirm the presence/absence of nasal polyps 1
• Warning signs requiring urgent evaluation: orbital swelling/pain, forehead swelling, diplopia, visual changes, neurological symptoms 1

Treatment Algorithm

1. First-Line Medical Therapy

• Intranasal corticosteroids

  • Recommended for nasal congestion and overall symptom control 1
  • Particularly effective in patients with marked mucosal edema
  • Helps decrease inflammation, swelling, and white blood cell influx 3

• Saline irrigation

  • Prevents crusting of secretions
  • Facilitates mechanical removal of mucus
  • Improves mucociliary transit times 1

2. Antibiotic Therapy (for bacterial sinusitis)

• First-line antibiotic: Amoxicillin-clavulanate 1, 4

  • Duration: 10-14 days for acute disease 2, 1

• Alternative antibiotics (for penicillin-allergic patients):

  • Cefpodoxime proxetil
  • Cefuroxime axetil
  • Cefdinir
  • Trimethoprim-sulfamethoxazole 1
  • Azithromycin (500mg once daily for 3 days) has shown 88% clinical cure rate at Day 7 for acute bacterial sinusitis 4

• Treatment failure: If no improvement in 3-5 days, consider alternative antibiotic 2

3. Additional Therapies

• For allergic component:

  • Consider referral to allergist/immunologist for patients with chronic or recurrent sinusitis 1
  • Fluticasone propionate nasal spray (200 mcg once daily) has shown significant relief of sinus pain and pressure in patients with allergic rhinitis 5

• For GERD-related sinusitis:

  • Medical treatment of GERD can result in significant improvement in sinusitis symptoms 2

4. Surgical Intervention

• Consider only after failure of maximal medical therapy:

  • Full 6 weeks of saline irrigations
  • Complete course of antibiotics
  • 6 weeks of intranasal corticosteroids 1

• Requirements for surgery:

  • Objective evidence of disease on CT imaging
  • Correlation between CT findings and symptoms
  • Re-evaluation of patient's symptoms and condition 1

• Surgical options:

  • Balloon sinus dilation for appropriate cases
  • More extensive surgery for cases with nasal polyps, osteitis, bony erosion, or fungal disease 1

Special Considerations

Chronic Sinusitis Subtypes

• Chronic hyperplastic eosinophilic sinusitis (noninfectious form) 2
• Fungal sinusitis (more common in southeast and southwest US) 2
• Patients with nasal polyps may require:
  • Short course of oral corticosteroids
  • Followed by topical intranasal steroids 1

Associated Conditions

• Asthma: Medical and/or surgical management of sinusitis can result in objective and subjective improvement of asthma 2
• Otitis media: Often associated with sinusitis 2
• Immunodeficiency: Consider testing in cases of recurrent sinusitis 2
• Cystic Fibrosis: Consider testing in children with nasal polyps, Pseudomonas colonization, or early-onset chronic sinusitis 2

Common Pitfalls to Avoid

• Overuse of antibiotics for viral infections 1
• Prolonged use of topical decongestants (should be limited to no more than 3 days) 6
• Failure to distinguish between viral rhinitis and bacterial sinusitis 1
• Inadequate duration of antibiotic therapy for acute bacterial sinusitis 2, 1
• Proceeding to surgery without adequate medical therapy or without objective evidence of disease on CT imaging 1
