Hypoglossal Nerve Stimulation Therapy for Pediatric Obstructive Sleep Apnea: A Meta-Analysis

초록

Background/Objectives: This study evaluates the efficacy of hypoglossal nerve stimulation as an alternative intervention for pediatric patients with obstructive sleep apnea (OSA) unresponsive to standard therapies and examines the uniformity of therapeutic outcomes across different patient cohorts. Methods: An extensive systematic search was performed across four principal databases (PubMed, EMBASE, Cochrane Library, and Web of Science) utilizing keywords associated with pediatric OSA and hypoglossal nerve stimulation, encompassing studies up to July 2025 that provided objective polysomnographic metrics (e.g., apnea-hypopnea index [AHI] values) to enable the quantitative assessment of pre- and post-intervention effects in children. The primary outcome measured was the ratio of means (ROM), determined from pre–post data in single-group studies, with summary estimates obtained using the fixed-effects model. Results: The systematic review included nine eligible studies with a total of 140 pediatric subjects, the majority of whom were adolescents with Down syndrome. AHI meta-analysis outcomes indicated a marked improvement in OSA severity, yielding an overall ROM of 0.57 [95% confidence interval: 0.49–0.65]. The therapeutic benefit demonstrated a high degree of uniformity across cohorts, as indicated by minimal statistical heterogeneity (I2 = 16%, p = 0.30). Funnel plot assessment showed no statistically significant evidence of systematic publication bias. Conclusions: Current evidence suggests that hypoglossal nerve stimulation therapy is a safe, effective, and valuable alternative for pediatric OSA patients who do not respond to conventional therapies.
