Patient: The nostril is not ventilated and causes headache. After surgery, one nostril is still not ventilated and yellow liquid comes out every day. A: Has there been an outpatient review after surgery? Is it persistent or intermittent non-ventilation? Because if all the inferior turbinates are removed, hyperventilation after surgery, there will also be atrophic rhinitis, nasal dryness, etc., so nasal turbinate surgery, most of the turbinates will remain part of the operation. There is yellow fluid flow every day, more or less. Generally is inflammation, commonly used nasal sprays such as endosolna and reno-cort can improve.
