Sinusitis surgery in the past sinusitis was treated by some ancient method, let’s say taking a capsule, a nasal mirror, and doing this surgery under the frontal mirror. Now almost all the second- to third-degree hospitals in the country are doing it under a nasal endoscope, and then it’s a minimally invasive nasal surgery, so all the incisions are made in the nasal cavity, a mirror is placed in the nasal cavity, and then the patient’s nasal anatomy is revealed in the TV mirror. So we operate with a minimally invasive enlarged anatomy, and the incision is made inside the nasal cavity, so there is no wound on the outside of the nasal cavity. Routinely before the operation, you have to cut your nasal hair, not to catch a cold, avoid tuberculosis, hypertension, diabetes, etc. When you have some underlying diseases, they should all be controlled in a stable state, and then actively cooperate with the preoperative examination, and if there are no contraindications to surgery, the surgery can be performed.
