The first follow-up visit is very important! Generally, patients in our hospital may be discharged soon after surgery, and before discharge, the bedside doctor will clean the patient’s nasal cavity once, but because the cleaning is arranged 2-3 days after the surgery, at this time the patient’s nasal cavity is still in a more serious state of edema, the doctor can only remove part of the oozing and blood accumulation in the nasal cavity, and a large amount of oozing from the middle nasal tract, absorbable filling materials can not be completely removed. If forcibly removed, but caused the patient’s pain, bleeding, so that the patient left a psychological shadow, and even some patients told the doctor that “the operation is not so difficult, but cleaning the nasal cavity is very painful for me.” The first post-operative follow-up is usually one week after discharge from the hospital, when the edema of the surgical cavity has been reduced, and the middle nasal passage is relatively easy to be exposed when cleaning, and the patient can tolerate it better at this time. At this time, the accumulated blood, absorbable stuffing material, pseudomembrane, etc., can be thoroughly removed from the surgical cavity, and the accumulated blood in the sinus cavity can be attracted cleanly. Generally, at the end of the cleaning, the patients often say, “After the surgery, I feel that my preoperative symptoms have been reduced a lot, and I don’t think there are still so many things in my nose. Although we did a very good job in the surgery, the patient’s nose has problems again after a few months or even a few years, and when they come back to the doctor for checkups, they will find that the surgical cavity has been adhered to all over the place, and then they miss the best time to clean up the nose, and it is too late to regret.
