ABSTRACT
OBJECTIVE@#To evaluate the curative effect of endoscopic sinus surgery (ESS).@*METHOD@#Two hundred and fifty-six cases with chronic sinusitis and nasal polyps, undergone ESS from 2001 to 2007 were analysed. There were 106 cases in type 1, 134 cases in type 2 and 16 cases in type 3. Two hundred and forty-six cases undergone ESS with intranasal local anesthesia and potentialized anesthesia. Long-time follow-up was performed at 9 to 42 months (mean = 15 months).@*RESULT@#The results showed that cure rate was 78.3% for type 1, 66.4% for type 2 and 43.8% for type 3. There was significant difference in cure rate between type 1, type 2 and type 3 (P < 0.01). Complication of ESS of 256 cases was 4.3%.@*CONCLUSION@#There was higher efficacy and safety for relief of nasal polyps and for relief of chronic sinusitis with ESS. The difference of clinical type in nasal polyps and chronic sinusitis affected directly surgical result.
