Blocked sinuses: There may be anatomic airway/nasal deformity, like a deviated nasal septum, overgrown bone (turbinates), or bone at the holes that aerate sinuses. The mucous membranes may swell and block the natural air holes into the sinuses, along with mucous or bacterial exudate (pus). Finally, there are some soft tissue masses (tumors) that can also block these holes. Smoking also aggravates tissues.
