Abstract: Objective To analyze the related factors affecting the postoperative prognosis of chronic rhinosinusitis(CRS)patients, and to provide effective reference for the treatment of patients with CRS. Methods Ninety CRS patients in our hospital from May 2014 to November 2015 were randomly selected and confirmed by sinus coronal CT scan and nasal endoscopic examine. All patients underwent endoscopic sinus surgery after continuous glucocorticoid nasal spray(200 μg per diem)and anti-inflammation therapy for 3 days. The related factors affecting the surgical treatment effect were analyzed. Results Before surgery, patients had very serious symptoms of head pain, rhinobyon and postnasal drip, which were effectively improved after treatment. But there is no significant improvement in general discomfort and hyposmia symptom. There were marked differences between the postoperative visual analog scale(VAS)score and 24 weeks and 48 weeks after surgery. Patients with nasal polyps or not, the long-term use of nasal congestion or not, has the history of sinus surgery or not, adhere to the implementation of the comprehensive treatment after surgery or not were related factors affecting the postoperative prognosis. Conclusion Nasal endoscopic surgery is effective in the treatment of patients with CRS, and can effectively improve the clinical symptoms. Acquaintance with patients past history, detection of allergens and implementation of comprehensive therapy after surgery is very important to improve the surgical effect.
