In clinical work, often after we tell patients that they must return to the hospital for regular review after surgery, there are still a small number of patients who can not come for timely review for various reasons, and now with the help of the good doctor platform, we will communicate with new and old patients on this issue. First of all, rhinology has its own specificity from the professional point of view, each person has four groups of sinuses, including maxillary sinus, sieve sinus, frontal sinus and pterygoid sinus, these structures are anatomically deep in the frontal and anterior rhinoscopes to determine the prognosis and severity of the disease is far from enough. Secondly, nasal diseases such as nasal polyps, sinusitis and involutional papilloma have a prominent feature that they are prone to recurrence, and the recovery of the nasal mucosa after surgery usually takes about half a year. During this period of time, the nasal mucosa will appear edema, vesicles, granulation and other common phenomena, these problems will continue to interfere with the recovery of the nasal mucosa of the operative cavity. If these problems are not cleared up in time and the nasal mucosa fails to return to normal for a long period of time, it can lead to reoccurrence of the disease. Thirdly, the doctor will clean up the vesicles, granules and other diseased tissues in a timely manner during the review, and at the same time will instruct the patient to take medication according to the review situation in order to promote the recovery of the nasal mucosa, and when the nasal mucosa is completely restored to normal, the likelihood of recurrence will be greatly reduced. Therefore, regular review after nasal endoscopic surgery is important and exceptionally necessary, each patient should pay attention to each postoperative review as much as the surgery, and adjust the amount of medication as prescribed by the doctor after the review, so as to ensure the effect of postoperative recovery. Many patients are concerned about how often they should come for a review. Generally speaking, the first review will be conducted 1 week after the surgery, at which time the doctor will carry out a thorough cleaning of the nasal cavity, removing blood clots and scabs in the nasal cavity, in order to prevent adhesions in the nasal cavity and promote wound healing. Then, depending on each patient’s recovery and the type of surgery, 2-4 checkups will be conducted within one month after the surgery. In the first six months, the checkups are usually conducted once a month, once every 2-3 months in the second six months, and once every six months thereafter.
