Comparison of Post-operative Pain Between Pulsed Electron Avalanche Knife (PEAK) and Electrocautery in Uvulopalatopharyngoplasty

Performing sleep surgery using electrocautery causes significant pain due to thermal tissue injury. A pulsed Electron Avalanche Knife (PEAK) can cut through tissue at lower temperatures, and is expected to reduce post-operative pain. Therefore, in this study, we attempted to compare post-operative pain between PEAK and electrocautery for uvulopalatopharyngoplasty (UPPP). [Article in Chinese]
