Interstitial radiofrequency (RF) surgery of the soft palate (SP) is an established option in the treatment of habitual snoring. The decision making process in the management of habitual snoring would benefit from diagnostic guidelines for oropharyngeal findings. The aim was to investigate the correlation of systematic clinical pretreatment oropharyngeal examination scores with the efficacy of interstitial RF surgery of SP in a multi-center study
