[Postoperative effects of balloon sinuplasty on chronic rhinosinusitis: a Meta-analysis].

Objective To evaluate the postoperative clinical effects of balloon sinuplasty on chronic rhinosinusitis. Methods PubMed, OVID, Embase, Cochrane Library, Proquest, Web of Science, Sinomed, Wan Fang and CNKI database (from established time to March of 2017) were searched for trials about the chronic rhinosinusitis treated by balloon sinuplasty. The relavent literatures were screened, and the prospective control studies were chosen. Lund-Mackay and SNOT-20 scores were used as the outcome idicators, and the methodological quality of the literatures were evaluated strictly. The extracted data were analyzed by Revman 5.3 software. Results A total of 7 prospective before-after self-controlled studies were included, and the overall quality of which was relatively high. Meta-analysis showed that the Lund-Mackay scores at 6 months post-operation, the SNOT-20 scores at 6 months and more than 1 year post-operation were significant lower than baseline when balloon sinuplasty used in the surgery; the SNOT-20 scores at more than 1 year post-operation was lower than baseline when a standalone ballon sinuplasty was performed. All the results was statistically significant (P<0.05), and all the SMD were more than 0.8. Conclusions The postoperative effect of balloon sinuplasty on chronic rhinosinusitis is obvious, and the subjective symptoms in patients is relieved effectively.
