How long after surgery does recurrence usually occur? Patients are concerned about this question. Clinically, we have found that if the postoperative wound does not complete epithelialization (the medical term for the ideal state of healing is epithelialization) it is indicative of recurrence. Usually, during the recovery period of 3-6 months after surgery, the wound either epithelializes or develops pathological changes such as adhesions, formation of patches at the wound, and narrowing or complete closure of the sinus opening. Therefore, if the patient fails to achieve the desired standard of epithelialization even 1 year after surgery, then it is highly likely to recur. Postoperative nasal recovery is divided into three stages We generally divide the postoperative sinus recovery into three stages. The first stage is the cleansing stage, which is within 3 weeks after surgery. At this stage, the patient’s nasal cavity will be oozing blood – coagulation – crusting, and the mucosa is still edematous. So the patient needs to go to the hospital at that stage for the doctor to help clean up the blood crust and clear the way for the later battle. The second stage is the competition between good and evil, which is within 2 weeks to 12 weeks after surgery. During this stage, the regeneration and epithelialization of the mucosa, and the pathological changes are competing with each other, so this period is very critical. Patients need to actively cooperate with the doctor for review and use medication as prescribed to help the righteous side gain the upper hand. The third stage is the consolidation of the fruits of victory (completion of epithelialization), within 12 weeks to 6 months after surgery. Reasonable postoperative review and cleanup with medication control allows the pathological changes to disappear and the wound to complete epithelialization. The completion of these three stages is indicative of a complete success of the surgery. It is too late to judge recurrence by symptoms. Some patients say that all my symptoms have improved well after surgery, so I am sure there is no recurrence and I don’t need to go to the hospital for a review! This concept should not be taken. This is because many recurrences have no clinical symptoms, but the doctor can find edema, cystic hyperplasia and retention of secretions in the mucosa of the sinus opening through nasal endoscopy, and the recurrence can be nipped in the bud with medication at this time. If you wait for symptoms, the condition is usually more serious and requires another surgery to treat, which is more than worth the cost.
