Acute sinusitis is usually bacterial in origin. A URI or severe allergic rhinitis leading to obstruction of the ostia and stasis of drainage often precedes it.
Haemophilus influenzae and Streptococcus pneumoniae are the organisms most commonly found in adults. In chronic sinusitis, the infecting organisms are variable, and a higher incidence of anaerobic organisms is seen (eg, Bacteroides, Peptostreptococcus, and Fusobacterium species).
In children, similar organisms are seen, with the addition of Moraxella catarrhalis. In older children and young adults, Staphylococcus aureus is an occasional finding.
In systemically impaired hosts, Candida, Aspergillus, and Phycomycetes may be the cause. Risk factors include the following: diabetes mellitus, cancer, hepatic disease, renal failure, burns, extreme malnutrition, and immunosuppressive diseases. [
