[Logistic regression analysis on influence factors of chronic sinusitis after endoscopic sinus surgery]

To explore the clinical effect and the influence factors after endoscopic surgery for chronic sinusitis.

The clinical data of 337 patients with chronic sinusitis treated by endoscopic surgery were analyzed, including gender, age, culture level, course of the disease, the days of hospitalization, medical history, smoking, drinking, early surgery history, allergic rhinitis (AR) history, clinical classification, visual analogue scale (VAS) score, nasal endoscopy score, nasal polyps, CT examination score, side, nasal adhesion and postoperative follow-up compliance. The clinical effect of endoscopic sinus surgery was evaluated 6 months after operation according to the 1997 Haikou standard. SPSS 18.0 software and conducted chi-square test and logistic regression analysis were used to analyze the data.

Three hundred and thirty-seven chronic sinusitis patients were followed up after endoscopic surgery. It was found that 298 cases (88.4%) cured, 29 cases (8.6%) improved, 10 cases (3.0%) invalid. The clinical curative effect of the patients with chronic rhinosinusitis without nasal polyp was better than that of the patients with chronic rhinosinusitis with nasal polyp, the difference was statistically significant (χ(2) = 10.932, P < 0.01). After many factors Logistic regression analysis, the most important effect factor in the clinical curative effect were clinical type, AR or not, VAS score, nasal endoscopic examination score, CT examination score, multiple nasal polyp or not, postoperative nasal adhesion or not and postoperative follow-up compliance.

The clinical effective of endoscopic sinus surgery is influenced by not only surgery itself, but also by clinical classification, whether and not with AR and so on.
