WebMar 21, 2010 · Other suggested benefits of nasal saline irrigation include enhanced ciliary beat activity, removal of antigen, biofilm, or inflammatory mediators, and a protective role on sinonasal mucosa . Nasal irrigation is also particularly useful after endoscopic sinus surgery to clear crusts and thick mucus that are common postoperatively ( 5 ). WebSep 11, 2024 · The ciliary beat frequency is dependent on dynein ATPase activity and the ability of cilia to increase it in response to various stimuli. Agents that were shown to increase CBF are beta 2 agonists, cholinergic drugs, adenosine triphosphate and phosphodiesterase inhibitors, mostly through a Ca 2+ /cAMP-dependent manner [ 108 ].
