Objectives: Current opinion for the treatment of obstructive sleep apnea (OSA) leans towards minimal invasive procedures. The frequently used radiofrequency ablation technique for the treatment of tongue base hypertrophy is a favorable alternative. In our study, we aimed to evaluate our complication rates and evaluate our experiences with radiofrequency application to the tongue, which we have preferred for the treatment of OSA since 2004. We planned to compare our complications rates with those in literature.

Methods: Seventy-five patients with OSAS treated in our clinic, between 2004-2009, using radiofrequency, were retrospectively evaluated regarding the rate and type of complication.

Results: There were no intraoperative complications. 9 out 75 patients (1.2%) had complications where 7 of them were observed in the first week. Two others were observed further on after treatment. 4 patients had mucosal ulceration, 2 patients had odynophagia, 1 patient had temporary nerve paralysis and 2 patients had abscess formation. All the patients that had complications were treated medically. None of them had airway obstruction.

Conclusion: Tissue ablation with radiofrequency, which is an option for minimally invasive surgical treatment of tongue base hypertrophy, is a frequently used modality. However debates over the amount of energy to use and the pattern of application, are still on going. Even though there are different results for complication rates in the recent literature, compared to other surgical techniques, radiofrequency is still a reliable and effective treatment.
