A considerable number of patients with nasal diseases often attach great importance to surgery, but do not understand the post-surgical follow-up very well, which often makes the surgery not have the best effect, and some of them even need surgery again for recurrence. Nasal disease is obviously different from other parts of the disease, most of the nasal diseases are easy to recur, but if the quality of the surgery can be guaranteed, adhere to the post-surgery review, the chance of recurrence is greatly reduced. Because the recovery of the nasal mucosa after surgery takes about 3 months to half a year, during this time, the formation of mucosal edema, vesicles, and granulation constantly interferes with the normal recovery of the mucosa of the surgical cavity. Therefore, it is necessary to find a doctor to review regularly, the doctor will guide the medication according to the situation of the surgical cavity, and timely clean up the diseased tissues, some patients will be adherent to the nasal cavity, it is more important to deal with the timely treatment, to promote the early recovery of the mucosa, to be completely restored to the mucous membrane of the surgical cavity to achieve a cure. The first follow-up is usually 1 week after the operation, and 1 time per week within 1 month, the doctor will clean the nasal cavity once under the nasal endoscopy, in order to clean the blood clots and scabs in the nasal cavity, in order to promote the wound healing and prevent the adhesion of the nasal cavity. Then, the follow-up is usually once a month in the first six months, once every 2-3 months in the second six months, and once every six months thereafter. Patients should pay attention to the prevention of upper respiratory tract infection after the operation, and perform nasal rinsing every day.
