Plasma radio-frequency ablation in treatment of obstructive sleep apnea hypopnea syndrome

Objective: To investigate the clinical effect of plasma radio-frequency in treatment of obstructive sleep apnea hypopnea syndrome(OSAHS).Method: Thirty-eight cases of OSAHS were treated by plasma radio-frequency ablation and the clinical data of these cases were also retrospectively analyzed.Results: The operation time was 8-15 min,hemorrhage was 2-15 ml.At post-operative 6 months,56% cases had an effect,41% had an improvement,and 3% had no effect,and the total effective rate was 97%.At post-operative 12 months,53% had an effect,38% had an improvement,and 9% had no effect,and the total effective rate was 91%.The longest time of apnea,the longest time of hypopnea,the lowest SaO2 and apnea-hypopnea index were statistically significant before and after operation,but there was not a significantly different between post-operative 6 and 12 months.Conclusion: Plasma radio-frequency ablation is convenient,simple and safe for obstructive sleep apnea hypopnea syndrome.
