Rhinomanometry is a non-invasive test that measures how easily air flows through your nose when you breathe. It helps doctors assess nasal airway resistance, which means how much effort it takes to breathe through your nose. Think of it as a way to check if your nose is functioning like a clear tunnel—or if it’s more like a narrow, blocked pipe.

Nasoendoscopy is a procedure to examine the internal structures of the nose and throat. It’s a tool the doctor uses to help diagnose various conditions, including enlarged adenoids, nasal polyps or allergic rhinitis (hayfever).
