ObjectiveThe aim of this study was to evaluate the advantages and feasibility of using the GlideScope video laryngoscope (GSVL) (Saturn Biomedical Systems, Burnaby, BC) in radiofrequency tongue base reduction for patients with obstructive sleep apnea syndrome (OSAS).MethodsPatients suffering from mild to severe OSAS associated with predominant tongue base obstruction (grade 3-4 Mallampati score) confirmed with physical examination who applied to our clinic during the first half of 2007 were included in our study. Seven-watt bipolar radiofrequency was applied to each patient's tongue base assisted by the GSVL at five to seven different locations for 30 to 35 seconds, resulting in energy application in a range of 210 to 245 J. All operations were carried out by the same surgeon, and patients were observed for 15 days postoperatively for any complications.ResultsTwelve patients were included in our study. Six of our patients were male and the other six were female. Each patient underwent a session of GSVL-assisted tongue base radiofrequency with a mean energy application of 210 to 245 J via five to seven punctures. The use of the GSVL assisted in a more thorough observation of tongue base anatomy, which aided in our aim to avoid the neurovascular bundle. The use of the GSVL during tongue base radiofrequency surgery creates a safer operation site and allows the surgeon to feel more confident during the procedure. The fact that we encountered no postoperative complications endorses our theory.ConclusionThe use of the GSVL in tongue base radiofrequency application not only creates a safer operative site and makes the procedure more uncomplicated but also could be an effective method that could be used in teaching hospitals for the education of otolaryngology surgeons regarding the tongue base radiofrequency procedure.
