Anatomical variations that narrow the ostiomeatal complex, including septal deviation, paradoxical middle turbinates, and Haller cells, make this area more sensitive to obstruction from mucosal inflammation. Mechanical obstruction of the ostiomeatal complex from foreign bodies, polyps, or tumors can also result in acute sinus disease. Systemic diseases that result in decreased mucociliary clearance, including cystic fibrosis and Kartagener syndrome, can be predisposing factors for acute sinusitis in rare cases. Patients with immunodeficiencies (eg, agammaglobulinemia, combined variable immunodeficiency, and immunodeficiency with reduced immunoglobulin G [IgG]– and immunoglobulin A [IgA]–bearing cells) are also at increased risk of developing acute sinusitis.
