Minimally invasive, single-staged multilevel surgery (MISS MLS) could be an optimal treatment for selected patients with obstructive sleep apnea (OSA). We aim to systematically review the efficacy of MISS MLS for patients with OSA, as well as the clinical outcomes and possible complications in OSA patients before and after MISS MLS.

Systematic review and meta-analysis. Six databases were searched, and the PRISMA guideline was followed.

Patients with OSA receiving MISS MLS.

The random-effects model was adopted for the statistical synthesis. The percentage and 95% confidence interval (CI) were adopted as the effect measurements of MISS MLS for OSA. Subgroup analyses and sensitivity analyses were also performed to identify the heterogeneity among the studies.

There were initially 154 articles for identification. Eventually, six studies with a total of 848 OSA patients completely met the inclusion criteria and were further enrolled for analysis. The pooled analysis showed statistically significant lower AHI (apnea/hypopnea index, /hr.; mean difference: -8.931, 95% CI: -11.591 to -6.271, I²  = 87.4%), ESS (mean difference: -2.947, 95% CI: -4.465 to -1.429, I²  = 94.9%), and snoring severity with 0-10 visual analog scale after surgery (mean difference: -4.966, 95% CI: -5.804 to -4.128, I²  = 96.4%). The success rate was 46% in mild/moderate OSA; however, 18% in severe OSA. There were no major complications occurred.

The acceptable surgical outcomes, esp. in mild/moderate OSA, and rare complications are the major advantages of MISS MLS. The evidence of this study could aid the decision making in selecting suitable treatment programs for OSA patients.
