While using a neti pot is probably the most-recognized over-the-counter method of deep nasal irrigation, one study 4 evaluated other irrigation techniques to discover which would more effectively reach the maxillary sinus and frontal recess after an endoscopic sinus surgery. For example, by flushing out pollen in the nose and sinus cavities, it helps to manage the symptoms of mild to moderate allergic rhinitis. 3 Nasal irrigation with a neti pot instills normal saline into your nasal passages with a small device that resembles a teapot.ДЄfter inserting the end of the pot in one side of your nose, the solution moves around the sinuses and out the other nostril. You may be familiar with nasal irrigation when itвЂ™s referred to as using a Neti Pot.ДЄccording to a 2009 article in the American Family Physician, 2 nasal irrigation has been an adjunctive therapy for upper respiratory conditions and is currently prescribed after nasal and sinus surgeries.
