Nasal polyps are mostly seen in adults and are caused by long-term edema of the nasal mucosa, with metaplasia and chronic inflammation as the main causes. Clinical manifestations can be progressive nasal congestion, increased nasal discharge, olfactory disturbance and headache. It can be single or multiple, unilateral or bilateral, but most of them are multiple and bilateral. Most polyps need to be treated by surgery, but recurrence after surgery has been the main problem for patients with nasal polyps.
Treatment with nasal endoscopic surgery is used to completely remove nasal polyps. This is the guarantee to reduce the recurrence rate after surgery. Since nasal polyps are mostly not only confined to the nose, but can also invade the sinuses in the surrounding area, the traditional method of removing nasal polyps using a trap is prone to recurrence. Nasal endoscopic surgery can not only reach deeper and hidden areas to completely remove nasal polyps, but also reduce the recurrence rate of nasal polyps through surgical operations that conform to the physiological functions of the human body. Due to the limitations of laser and microwave, patients must be very careful when choosing to use laser, microwave, etc. to treat nasal polyps.
