The quality of relevant studies was assessed using NIH quality assessment tool for observational cohort and cross-sectional studies as well as NIH tool for quality assessment for case series studies. <strong>Results:</strong> Meta-analyses of relevant studies showed that the surgical technique that achieved the best reduction on AHI (Apnea/Hypopnea Index) was the lateral pharyngoplasty followed by the Anterior Palatoplasty, with a significant mean reduction of [(SMD = −0.848, 95% CI (−1.209 - −0.487), p-value < 0.001) and (SMD = −0.864, 95% CI (−1.234 - −0.494), p-value < 0.001), respectively]. The technique responsible for the best improvement in Epworth Sleepiness Score (ESS) was the Relocation Pharyngoplasty, with a significant mean reduction of [SMD = −0.998, 95% CI (−1.253 - −0.743), p-value < 0.001]. Minimal O2 saturation level improved most with the Expansion Sphincter Pharyngoplasty, with a significant mean reduction of [SMD = 1.011, 95% CI (0.581 - 1.440), p-value < 0.001]. The surgical procedure that results in the best post-operative Visual Analogue Scale (VAS) was Z-Palatoplasty, with a significant mean reduction of [SMD = −1.551, 95% CI (−2.049 - −1.052), p-value < 0.001]. Soft palate length changes with a significant mean reduction of [SMD = −2.219, 95% CI (−2.730 - −1.708), p-value < 0.001]. Finally, meta-analyses of relevant studies showed that expansion sphincter pharyngoplasty achieved the overall highest success rate [event rate = 77%, 95% CI (65.4% - 85.5%), p-value < 0.001]. <strong>Conclusion:</strong> The best procedure for treating OSA varies from patient to patient and there is no universal cure-all. Careful patient selection and pre-operative evaluation are mandatory.展开更多
