Sinusitis
Sinusitis is defined as "an inflammatory process of the mucous membranes of the paranasal sinuses that occurs in three stages: acute, subacute, and chronic. Sinusitis results from any condition causing ostial obstruction or from pathophysiologic changes in the mucociliary transport mechanism."[1]
Etiology/causes
Microbiology
Diagnosis
History and physical examination
A systematic review by the Rational Clinical Examination concluded "maxillary toothache, poor response to nasal decongestants, abnormal transillumination, and colored nasal discharge by history or examination are the most useful clinical findings in primary care populations."[2] More recently reported is that a "red streak in the lateral recess of the oropharynx predicts acutesinusitis." (picture)[3]
CT Scan
For acute sinusitis, interpreting abnormal computed tomography scan results is difficult because most patients with a common cold will have abnormalities of the maxillary sinuses.[4]
For chronic sinusitis, computed tomography has many false positive results.[5]
Treatment
Antibiotics
Clinical practice guidelines by the Infectious Diseases Society of America recommend treatment if one of:[6]
- "Onset with persistent symptoms or signs compatible with acute rhinosinusitis, lasting for ≥10 days without any evidence of clinical improvement"
- "Onset with severe symptoms or signs of high fever (≥39°C [102°F]) and purulent nasal discharge or facial pain lasting for at least 3–4 consecutive days at the beginning of illness"
- "Onset with worsening symptoms or signs characterized by the new onset of fever, headache, or increase in nasal discharge following a typical viral upper respiratory infection (URI) that lasted 5–6 days and were initially improving (“double-sickening”)"
Clinical practice guidelines by the American Academy of Otolaryngology - Head and Neck Surgery address treatment and state:[7]
- "observation without use of antibiotics is an option for selected adults with uncomplicated ABRS who have mild illness (mild pain and temperature <38.3 degrees C or 101 degrees F) and assurance of follow-up"
Patients diagnosed without imaging
Many meta-analyses of this topic have been done.[8]
One patient in 15 benefit from antibiotics if their diagnosis is based on clinical findings without use of imaging according to one meta-analysis of individual patient data.[9] This number is improved to 8 if there is purulent rhinorrhea.
However, this most recent trial in the meta-analysis[10], and a subsequent trial[9], showed no benefit from amoxicillin.
Regarding choice of antibiotics, a second meta-analysis (not using individual patient data)concluded that respiratory quinolones (moxifloxacin, levofloxacin, or gatifloxacin) were not better than amoxicillin–clavulanate or 2nd and 3rd geneneration cephaolosporings.[11]
Topical corticosteroids do not seem to help patients who are diagnosed without imaging.[10]
Patients diagnosed with imaging
Topical corticosteroids
Topical corticosteroids may improve the resolution or improvement of symptoms.[12][13]
