The brain relies on the sinuses in various ways as well. Aside from providing clean, oxygen-rich air to the brain via the bloodstream, the sinuses aid the brain in several autonomic nervous system responses. For instance, we know that there is a nasopulmonary reflex that causes a drop in oxygen saturation levels throughout the body when your nose and/or nasopharynx are obstructed. I see this when there is a tissue mass in the nasopharynx or when packing is placed there to stop a nosebleed.
