Abstract
The inferior turbinate is composed of a central bony structure surrounded by ciliated pseudostratified columnar epithelium. Underneath the epithelium, there are mucous glands, goblet cells and venous sinusoids in the submucosa, The inferior turbinate is supplied by the inferior turbinate branch of the posterior lateral nasal artery from the sphenopalatine artery. The inferior turbinates humidify the air, trap particles and direct airflow throughout the nasal cavity. Due to these functions, the inferior turbinates are often the first point of contact for allergens in the inspired air. With immune responses prompted by a cascade of inflammatory mediators such as immunoglobulin E, mast cells, histamine, and leukotrienes, mucous glands become stimulated and the vasculature within the inferior turbinate engorges. This results in inferior turbinate hypertrophy, leading to increased nasal discharge and nasal obstruction. For individuals refractory to medical therapy for nasal obstruction, surgical inferior turbinate reduction techniques can be employed to help alleviate the symptoms. For those with rhinorrhea refractory to medical therapy, surgical management aimed at reducing parasympathetic innervation to the nasal cavity to reduce nasal discharge production can be also option.
