To investigate the value of nasal endoscopy in the surgery of the nasal inverted papillomas.29 patients with nasal inverted papilloma, 15 cases of them were applied nasal endoscopic surgery (nasal endoscopic surgery group), 14 cases were applied nasal lateral incision surgery(nasal lateral incision group), and compared the results of the two surgery.Follow-up 1.8 years.nasal endoscopic surgery group(1 case) was obviously lower than nasal lateral incision group(5 cases), P < 0.01; The hospitalization time: nasal endoscopic surgery group(13.1 d) was obviously short than nasal lateral incision group(20.4 d), P < 0.01; The volume of blood during surgery(I-II stage): nasal endoscopic surgery group(175 ml) was obviously lower than nasal lateral incision group(525 ml), P < 0.01;The nasal endoscopy was a better method for treating I-II stage nasal inverted papilloma, and the major advantage is an incision of the face can be avoided. As to III-IV stage disease, should be carefully selected endoscopic surgery. Nasal lateral incision surgery still was a safe and reliable therapeutic method.
