What are the symptoms and treatment options for Pan Sinusitis (Pansinusitis), an inflammation of all sinuses?

From the Guidelines

Pan sinusitis should be treated with conservative measures, including nasal saline irrigation and intranasal corticosteroids, and antibiotics such as amoxicillin-clavulanate for bacterial cases, with careful consideration of potential complications and the need for further evaluation or specialist referral. The treatment of pan sinusitis typically begins with conservative measures, including nasal saline irrigation 2-3 times daily and intranasal corticosteroids like fluticasone (2 sprays in each nostril once daily) or mometasone (2 sprays in each nostril once daily) 1. For bacterial pan sinusitis, antibiotics are recommended, with amoxicillin-clavulanate (875/125 mg twice daily for 5-7 days) being the first-line choice due to its coverage against common pathogens including beta-lactamase producers 1. Alternatives for penicillin-allergic patients include doxycycline (100 mg twice daily) or levofloxacin (500 mg daily for 5-7 days) 1. Pain relief can be achieved with acetaminophen or NSAIDs like ibuprofen. Decongestants such as pseudoephedrine may provide temporary symptom relief but should be limited to 3-5 days to avoid rebound congestion. If symptoms persist beyond 7-10 days of treatment, worsen after initial improvement, or include high fever, severe headache, or visual changes, further evaluation is necessary as complications like orbital cellulitis or intracranial spread may occur 1. Some key points to consider in the treatment of pan sinusitis include:

• The importance of distinguishing between viral and bacterial causes of sinusitis, as antibiotics are only effective against bacterial infections 1
• The potential for complications, such as orbital cellulitis or intracranial spread, which require prompt evaluation and treatment 1
• The need for further evaluation or specialist referral in cases of recurrent or chronic pan sinusitis, or in cases where symptoms persist or worsen despite treatment 1
• The use of imaging studies, such as CT or MRI, in the evaluation of pan sinusitis, particularly in cases where complications are suspected or in cases of recurrent or chronic disease 1

From the FDA Drug Label

1. 4 Acute Bacterial Sinusitis: 5 Day and 10 to 14 Day Treatment Regimens Levofloxacin tablets are indicated for the treatment of acute bacterial sinusitis due to Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis [see Clinical Studies (14.4)].

PAN SINUSITIS treatment with levofloxacin is indicated for acute bacterial sinusitis due to specific microorganisms, including Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis.

• The treatment regimens are 5 Day and 10 to 14 Day. 2

From the Research

Definition and Diagnosis of Pan Sinusitis

• Pan sinusitis is a condition where all the sinuses in the head are inflamed, including the frontal, ethmoid, maxillary, and sphenoid sinuses.
• The diagnosis of pan sinusitis is typically based on clinical symptoms, such as facial pain or pressure, fever, and purulent nasal discharge, as well as imaging tests like computed tomography (CT) scans 3.
• The challenge lies in distinguishing between the symptoms of bacterial and viral sinusitis, as the treatment approaches differ significantly 3, 4.

Treatment Options for Pan Sinusitis

• Antibiotics are often prescribed for patients with severe symptoms or those who do not respond to initial treatment, with amoxicillin being a common first-line treatment 3, 4.
• For patients with a beta-lactam allergy, alternative antibiotics like doxycycline or respiratory fluoroquinolones may be used 3.
• Supportive care, including saline irrigation, nasal steroids or antihistamines, and decongestants, can help reduce the severity of symptoms 3.
• High-dose amoxicillin/clavulanate has been shown to be effective in treating acute bacterial sinusitis, especially in adults 5.
• The use of fluticasone nasal spray as an adjunct to amoxicillin has been found to be beneficial in reducing symptom severity in children with acute sinusitis 6.

Complications and Prevention

• Complications of pan sinusitis are rare but may include orbital cellulitis, meningitis, and abscess, highlighting the importance of prompt and effective treatment 3.
• The use of antibiotics like amoxicillin/clavulanate has been found to be effective in preventing the development of resistant bacterial strains 7.
• The development of new high-dose formulations of amoxicillin/clavulanate has improved the treatment of drug-resistant pathogens, such as Streptococcus pneumoniae 7.
