摘要:ObjectiveTo evaluate the significance of Chinese version of sinonasal outcome test22 (SNOT22) in the evaluation of posterior paranasal sinus lesions and to guide the perioperative care.Methods50 patients with posterior paranasal sinus lesions were included, and 50 healthy ones were chosen as control. The quality of life (QOL) statuses of the controls and those of the patients before operation, one, 3, 6 and 9 months after treatment were evaluated with Chinese version of SNOT22. The total scores and scores of each dimension between the controls and the patients before treatment, and those between the patients before and after treatment were compared. The correlations between QOL statuses, Jorgensen CT staging scores and SNOT22 scores of the patients were analyzed respectively.ResultsAfter treatment, the QOL in patients with posterior paranasal sinus lesions got improved significantly. There was a weak positive correlation between the preoperative scores of sinonasal Jorgensen CT staging and the Chinese version of SNOT22.ConclusionThe Chinese version of SNOT22 can be applied to effectively evaluate the preoperative QOL of patients with posterior paranasal sinus lesions, therefore provide references for treatment options and guide perioperative care.
