Yes, tear ducts are connected to the sinuses through a system of small passages. The tear ducts drain tears from the eyes into the nasal cavity, specifically through the nasolacrimal duct, which empties into the inferior nasal meatus. This connection is why your nose may run when you cry, as excess tears can flow into the nasal passages.
When air comes out of your tear ducts during nose blowing, it indicates a connection between the tear ducts and nasal cavity, possibly due to a tear duct blockage or nasal congestion. This condition can be uncomfortable but is usually not a serious concern. If persistent or bothersome, it's best to consult a doctor for further evaluation.
