The post-operative review of sinusitis depends on the specific condition of the individual patient, and there is no uniformly prescribed time and steps. For most patients, it may be divided into early review and late review, as follows: first, early review, mainly 1 to 2 weeks after the patient is discharged from the hospital, you can come to the hospital for nasal cavity cleaning treatment, mainly to clean up the nasal cavity blood crust and nasal secretions, you can come back to the hospital one to two weeks later to review, review mainly to avoid adhesions of the nasal mucosa, remove the nasal mucosa blood crust, dry crust and other secretions The main purpose of the review is to avoid the formation of fibrinous adhesions in the early stage. Secondly, after one month, it is mainly the late review, the late review time is once a month, some patients can also come once half a month, this review time lasts for three months to six months. During the post-check, the main concern is whether there is any local vesicle or granulation formation, whether there is any recurrence of polyps, whether there is any blockage of the sinus opening and other related changes. During the review, the doctor needs to perform endoscopic nasal clearance to remove the early vesicles and to separate the local adhesions to avoid affecting the ventilation over time. All in all, the post-operative review of sinusitis is scheduled by the doctor according to the patient’s condition, and the review is mainly a change of medication, and the patient himself needs to take oral medication to consolidate the treatment.
