The common diseases that require nasal endoscopic surgery in clinical practice are nasal septal deviation, chronic hypertrophic rhinitis, nasal polyps, chronic sinusitis, nasopharyngeal fibrovascular tumor, rhinitis, adenoid hyperplasia and other diseases. After completing the preoperative examination to assess that the patient can tolerate the surgery, endoscopic resection of the intranasal lesions under general anesthesia is required. The duration of hospitalization for this disease is approximately five days, and the postoperative nasal cavity is filled bilaterally with a tumescent sponge to stop bleeding and prevent perforation of the nasal septum or hematoma formation. On the third postoperative day, the expansion sponges were removed from both nasal cavities and the patient was discharged on the fifth postoperative day after the nasal cavity was cleared.
