bipolar electrocautery, CPAP, nasal obstruction, obstructive sleep apnoea, radiofrequency ablation


Objective: To investigate the treatment effect of radiofrequency ablation (RFA) on nasal obstruction, continuous positive airway pressure (CPAP) compliance, Epworth sleepiness scale (ESS) and sleep quality were compared with that of bipolar electrocautery (BEC) in patients using CPAP.
Material and Methods: Participants were randomised into two groups and treated with either RFA or BEC. Data were collected regarding nasal obstruction, total nasal symptoms, CPAP compliance, daytime sleepiness and sleep quality before and after treatment at 1, 3 and 6 months.
Results: Twenty-eight patients were enrolled in the study. Both methods relieved nasal obstruction at 1, 3 and 6 months. At 6 months, the symptom was improved by 83.4% and 64.2% in the RFA and BEC groups, respectively. The total nasal symptoms decreased at 3 and 6 months in both groups as well, exhibiting 75.7% and 40.6% improvement at 6 months in the RFA and BEC groups, respectively.
Conclusion: Both RFA and BEC have the ability to relieve nasal obstruction in such patients.
