Physical removal of irritants from nasal mucosa

Physical removal of irritants from the nasal mucosa refers to non-pharmacological interventions aimed at cleansing the nasal cavity of particulate matter, allergens, and pathogens. The process most commonly utilizes mucociliary clearance—a coordinated action of ciliated epithelial cells moving mucus toward the pharynx—and adjunctive therapies such as nasal irrigation using isotonic or hypertonic saline. These therapies are widely used for symptom relief in conditions like allergic rhinitis, chronic rhinosinusitis, and post-operative wound healing, offering benefits of reducing local inflammation, enhancing mucosal moisture, and facilitating clearance of mucus and debris. However, this is an intervention and not a discrete molecular target involved in signal transduction or cellular regulation.
