summarize this The sinuses rely on tiny hair-like structures called cilia to move mucus and foreign particles out of the nasal passages. Smoking impairs this mucociliary clearance mechanism, making it less efficient. As a result, mucus can accumulate in the sinuses, creating an environment conducive to infection.
