Özet
Objective: Obstructive sleep apnea syndrome (OSAS) is a complex disease involving multiple structures of the upper airway system. In our study we sought to evaluate the effect of bipolar radiofrequency induced thermo ablation on the volume of the tongue base using pre and post-procedure MRI scans. Material and Method: 12 patients that applied to our clinic with OSAS during March 2009-October 2009 were included in our study. Patients underwent pre-operative MRI and postoperative MRI 7 weeks after surgery. Outcomes included Epworth sleepiness scale and the modified Mallampati scale. 7 watt bipolar radiofrequency was applied to each patient's tongue base at 5-7 different locations for 45-55 sec resulting in energy application in a range of 315-385 joule. Results: After 1 session of radiofrequency ablation, MRI scans performed 7 weeks after surgery showed a 6.05% decrease in tongue base volume. An 8.51% increase in distance between the tongue base and posterior pharyngeal wall was also noted in our study. The Epworth sleepiness scale performed before and after surgery showed a pronounced decrease in patient symptoms. Visual analog scales used for the determination of pain and dysphagia showed a steady decrease in both symptoms from day 1. Pre-operative antibiotic prophylaxis with 2 gr of cefazoline was administered and no infections or other complications were observed. Conclusion: Bipolar induced thermoablation significantly decreases the size and bulk of the tongue base observed on MRI scans and lessens patient complaints after only 1 session.
