Sinusitis, which we now generally refer to as sinusitis, is diagnosed based on specific examinations and surgical interventions are considered when indicated. After surgery, regular follow-ups are necessary, along with nasal cavity cleaning to prevent the recurrence of sinusitis. Typically, after discharging the surgical patient, we advise them to return to the clinic for a follow-up after a week. Subsequently, based on specific conditions during the follow-up, patients are instructed to return for further check-ups after two weeks, four weeks, eight weeks, and even up to three months. This process should continue for about half a year, during which regular clinic visits for follow-ups are necessary. During these visits, the doctor will assess the healing of the sinus cavity and schedule the next follow-up appointment accordingly.
