Treatment for Sinus Problems
For acute bacterial sinusitis, start with intranasal corticosteroids and saline irrigation as first-line therapy, reserving antibiotics only for symptoms lasting 10-14 days or severe presentations with fever, purulent discharge, and facial pain. 1
Acute Bacterial Sinusitis Management
When to Use Antibiotics
- Reserve antibiotics for specific criteria only: symptoms persisting 10-14 days without improvement, OR severe acute infection with fever plus purulent nasal discharge, facial pain/tenderness, or periorbital swelling 1
- If antibiotics are warranted, use amoxicillin with clavulanate as first-line therapy (not amoxicillin alone), targeting Streptococcus pneumoniae, Haemophilus influenzae, and anaerobes 1
- Prescribe a 10-14 day course for acute disease; switch to an alternative antibiotic if no improvement within 3-5 days 1
First-Line Non-Antibiotic Therapy
- Intranasal corticosteroids reduce inflammation and are helpful as adjunctive therapy for acute and recurrent sinusitis 1
- Nasal saline irrigation (high-volume, using squeeze bottle or neti pot with isotonic or hypertonic solution 2-3.5%) provides symptomatic relief with minimal risk 2, 3, 4
- Topical decongestants (oxymetazoline 0.05%) provide rapid relief but limit use to 3-5 days maximum to prevent rhinitis medicamentosa 1, 2
Special Considerations for Comorbidities
For patients with hypertension, glaucoma, or cardiovascular disease:
- Avoid or use extreme caution with oral decongestants (pseudoephedrine) due to increased systolic blood pressure, heart rate, and risks in patients with arrhythmias, angina, coronary artery disease, or uncontrolled hypertension 1, 2
- Prioritize intranasal corticosteroids as the safest and most effective option for nasal congestion in these patients 2
- Topical decongestants should be avoided in patients with glaucoma, bladder neck obstruction, or hyperthyroidism 1, 2
For patients with asthma:
- Treating sinusitis (medically or surgically) results in objective and subjective improvement of asthma symptoms 1, 5
- Consider leukotriene receptor antagonists (montelukast) which have similar efficacy to oral antihistamines and may benefit both rhinitis and asthma 2, 6
Chronic Rhinosinusitis Management
Definition and Diagnosis
- Chronic rhinosinusitis requires ≥12 consecutive weeks of at least two cardinal symptoms: facial pain/pressure, hyposmia/anosmia, nasal drainage, or nasal obstruction, plus objective evidence on endoscopy or CT imaging 7
First-Line Treatment
- Daily high-volume saline irrigation combined with intranasal corticosteroid sprays is the cornerstone of chronic sinusitis treatment 7, 3, 4
- Hypertonic saline (2-3.5%) irrigation improves sinus-related quality of life, decreases symptoms, and reduces medication use; compliance averages 87% with minimal side effects 4
- Mandatory smoking cessation if applicable 7
Address Underlying Factors
- Evaluate for allergic rhinitis: Consider antihistamines, allergy testing, and immunotherapy if present, as allergic rhinitis augments bacterial sinusitis 1, 7, 5
- Screen for GERD: Medical treatment of gastroesophageal reflux disease results in significant improvement in sinusitis symptoms 1, 7
- Recognize asthma connection: Medical or surgical management of sinusitis improves asthma outcomes 1, 7
Role of Antibiotics in Chronic Sinusitis
- The role of antibiotics in chronic sinusitis is controversial 1
- For chronic infectious sinusitis with evidence of active bacterial infection, consider longer duration therapy (minimum 3 weeks, potentially up to 3 months) with attention to anaerobic pathogens 1, 7
- For chronic non-infectious (hyperplastic) sinusitis, consider systemic corticosteroids instead of antibiotics 1
When to Refer to Specialist
Consultation with an otolaryngologist or allergist/immunologist is indicated when: 1, 7
- First-line medical therapy fails after 8-12 weeks
- Sinusitis is refractory to usual antibiotic treatment
- Sinusitis is recurrent (≥3 episodes per year)
- Quality of life is significantly affected
- Need to clarify allergic or immunologic basis
- Associated with unusual opportunistic infections
- Complicating conditions present: chronic otitis media, nasal polyps, recurrent pneumonia, immunodeficiencies, aspirin sensitivity, allergic fungal disease
Surgical Considerations
- Functional endoscopic sinus surgery may be appropriate for medically resistant sinusitis, particularly with localized persistent disease in the ostiomeatal complex 1, 7
- Defer surgery until smoking cessation is achieved 7
Adjunctive Therapies
For Nasal Congestion
- Intranasal antihistamines (azelastine) are efficacious and equal to or superior to oral second-generation antihistamines for seasonal allergic rhinitis, with clinically significant effect on nasal congestion 1, 8
- Intranasal anticholinergics (ipratropium bromide) effectively reduce rhinorrhea but have no effect on other nasal symptoms; can be combined with intranasal corticosteroids for enhanced effect 1, 2
Antihistamines and Decongestants
- Avoid first-generation antihistamine/decongestant combinations due to significant sedation, performance impairment, and dangerous anticholinergic effects 2
- Second-generation oral antihistamines alone are less effective for nasal congestion than for other nasal symptoms 1, 2
- If oral decongestants are necessary, pseudoephedrine 60 mg every 4-6 hours is the only proven effective oral decongestant; phenylephrine should be avoided due to extensive first-pass metabolism 2
Other Supportive Measures
- Antihistamines, mucolytics, and expectorants may provide symptomatic benefit in selected cases 1
- Adequate hydration and fluids promote drainage 5
Common Pitfalls to Avoid
- Do not overdiagnose sinusitis or unnecessarily treat with antibiotics; appropriate criteria must be met 1
- Never use topical decongestants beyond 3-5 days due to risk of rhinitis medicamentosa 1, 2, 9
- Do not use oral decongestants in patients with cardiovascular disease, uncontrolled hypertension, glaucoma, or hyperthyroidism without extreme caution 1, 2
- Avoid phenylephrine as an oral decongestant; it is ineffective at standard doses 2
- Ensure proper nasal irrigation technique: use clean devices, proper salt concentration (2-3.5%), and clean thoroughly after each use to prevent infections 3
