Aka: Chronic Rhinosinusitis, Chronic Sinusitis
  1. See Also
    1. Allergic Fungal Sinusitis
  2. Epidemiology
    1. Prevalence: 1-5% in U.S.
  3. Pathophysiology
    1. Chronic Sinusitis is an inflammatory condition (along the lines of Asthma, Allergic Rhinitis)
    2. Mucous membrane loses normal function
    3. Contributing factors
      1. Inadequately treated Allergic Rhinitis
      2. Repeated cases of Acute Sinusitis (due to predisposing conditions such as Cystic Fibrosis)
    4. Inflammatory more than infectious, but typically mixed Bacterial flora are present
      1. Staphylococcus aureus
      2. HaemophilusInfluenzae
      3. Anaerobes (ID)
      4. Fungal organisms (immunocompromised patients)
    5. Other causes
      1. Allergic Fungal Sinusitis
  4. Risk Factors: Atypical cases
    1. Vasculitis (e.g. granulomatosis with polyangiitis) or Granulomatis disease (e.g. Sarcoidosis)
      1. May results in increased nasal inflammation and obstruction
    2. Cystic Fibrosis
      1. Poor mucociliary clearance
      2. Chronic Rhinosinusitis is very common in CF, and may predispose to pumonary infection
    3. Immunodeficiency
      1. Increased risk of fungal organisms
  5. Symptoms
    1. Facial pain or pressure (70-85%)
    2. Hyposmia or Anosmia or decreased or absent Sense of Smell (61 to 69%)
    3. Discolored nasal drainage (51-83%)
    4. Nasal obstruction (81-95%)
  6. Signs: Anterior rhinoscopy or Nasolaryngoscopy
    1. Mucopurulent nasal drainage
    2. Nasal mucosa edema
    3. Nasal obstruction
      1. Septal deviation
      2. Inferior or middle turbinate enlargement
      3. Middle meatus polyps
  7. Precautions: Red Flags suggestive of alternative diagnosis
    1. Nasal mass
    2. Diplopia
    3. Decreased vision
    4. Periorbital Cellulitis or edema
    5. Ophthalmoplegia
    6. Meningisimus
  8. Diagnosis
    1. At least 12 consecutive weeks of findings AND
    2. Objective evidence of Rhinosinusitis AND
      1. Exam with mucopurulent drainage, edema, middle meatus polyps (on anterior rhinoscopy or Nasolaryngoscopy) or
      2. Imaging (preferably Sinus CT) consistent with Sinusitis
    3. At least 2 of the following 4 cardinal symptoms
      1. Facial pain or pressure
      2. Hyposmia or Anosmia (decreased or absent Sense of Smell)
      3. Nasal drainage
      4. Nasal obstruction
  9. Imaging
    1. Sinus CT (non-contrast)
      1. Preferred imaging modality
      2. Radiation exposure <1 mSv
      3. False positive (e.g. after Upper Respiratory Infection)
    2. Sinus XRay
      1. Not recommended due to poor accuracy
  10. Management
    1. First-Line
      1. Intranasal Corticosteroids for 8-12 weeks
      2. Low pressure, high volume (240 ml) Nasal Saline irrigation (e.g. Neti Pot) three times daily
        1. Precede each dose of Intranasal Corticosteroid with saline irrigation
        2. Neti Pot type irrigation is significantly better than nasal spray
          1. Chong (2016) Cochrane Database Syst Rev (4):CD011995 [PubMed]
    2. Second-line: Systemic Corticosteroids
      1. Indicated for Nasal Polyps or more severe symptoms
      2. Limit oral Corticosteroids to short course (no longer than 3 weeks)
    3. Third-line: Antibiotics
      1. Indicated for signs of acute on Chronic Sinusitis (e.g. fever) or if not improved in 8-12 weeks
      2. Consider antibiotics guided by endoscopic sinus culture
      3. Amoxicillin-Clavulanate (Augmentin) for 2 weeks
      4. Doxycycline for 3 weeks (for antiinflammatory effects)
      5. Avoid longterm use (>3 weeks) due to poor benefit and associated risk

  11. Management: Refractory cases
    1. Surgery
      1. Septaplasty with or without turbinate reduction
      2. Endoscopic performed outpatient
        1. Removal of anatomic sinus block
        2. Improves symptoms in 85%
    2. Allergy Consultation
    3. Consider Immunologic work-up
  12. Complications
    1. Acute Sinusitis exacerbations
      1. Treat as Acute Rhinosinusitis with antibiotics
    2. Serious complications from Chronic Rhinosinusitis are rare
      1. Most of the following complications occur more commonly with Acute Bacterial Rhinosinusitis
      2. Periorbital Cellulitis or Orbital Cellulitis
      3. Orbital abscess
      4. Cavernous Sinus Thrombosis
      5. Meningitis
      6. Epidural Abscess
    3. Comorbities exacerbated by Chronic Rhinosinusitis
      1. Cystic Fibrosis
      2. Asthma

Chronic sinusitis (C0149516)

Definition (NCI) Inflammation of the paranasal sinuses that typically lasts beyond eight weeks. It is caused by infections, allergies, and the presence of sinus polyps or deviated septum. Signs and symptoms include headache, nasal discharge, swelling in the face, dizziness, and breathing difficulties.
