Distribution of nasal polyps in the study subjects was documented. Long-term quality of life assessment was carried out at 1-year after surgery by SNOT-20 analysis. Observation of a total of 214 sides of rhinal cavities revealed that nasal polyps were distributed inside the OMC at 573 sites out of the total 635 sites (90.2%), and predominantly distributed at the middle turbinate, the ethmoid sinus, the middle meatus, the uncinate process, the maxillary sinus, and the ethmoid bulla and significantly differed from the nasal polyps which were found outside the OMC (P<0.01). Statistical analysis indicated that pre-operative Sinonasal Outcome Test 20 (SNOT-20) scores and 1-year post-operative scores were statistically significant (P<0.05). The score changes of the left maxillary sinus, both sides ethmoid bulla were significant, respectively (P<0.05). Nasal polyps predominantly distribute in the OMC. The differences among the sites of nasal polyps do not significantly impact the long-term score for quality of life except for the maxillary sinus and ethmoid bulla.
