Multilevel radiofrequency ablation to the soft palate and tongue base: tips and pitfalls.

The objective of the study is to increase awareness and understanding of the techniques and safety measures to minimise complications and improve patient outcomes. Literature review using MedLine and keywords snoring; obstructive sleep apnoea; radiofrequency ablation; electrosurgery; palate; tongue base was conducted. There is no accepted gold standard technique for radiofrequency ablation; to date, there is no published literature regarding common tips and pitfalls in radiofrequency application specifically for superficial applications and second-stage surgery. Surgery for snoring and obstructive sleep apnoea is typically multilevel. Pre-operative patient assessment and selection are critical to ensure good outcomes. Radiofrequency is generally safe and efficacious in this subset of patients. However, as with all surgery, it is operator-dependent. In particular, we emphasise the methodology for second-stage surgery, optimising visualisation and avoiding ulceration/fistulation of the soft palate, which are previously undescribed in the literature.
