Long-term safety and efficacy of radiofrequency ablation in the treatment of sleep disordered breathing: a meta-analysis

Radiofrequency ablation (RFA) is used in the treatment of sleep disordered breathing (SDB), particularly in the alleviation of snoring. The literature provides evidence that the short-term results are promising; however, the long-term efficacy is a matter of contention. In this article, we present the results of a literature search of studies that use RFA in the treatment of SDB which have a follow-up time of greater than a year. RFA was found to be a safe technique with minimal morbidity. The overall Visual Analogue score from six studies showed the overall mean improvement to be 4.3 (confidence intervals 3.4-5.12). Apnea Hypopnea Index (AHI), improved significantly in five of the studies analysed. Epworth Sleepiness Score (ESS), improved significantly in six of the studies analysed. In conclusion, the evidence suggests that RFA for SDB results in a significant improvement in follow-up times of at least a year. Since RFA can be applied in a clinic setting and leads to minimal disruption to daily life, this treatment option can be considered for those unwilling to participate in the more traditional surgical options for SDB.
