The application of low-temperature plasma ablation for the treatment of adenoid hypertrophy is a world-class minimally invasive procedure with minimal side effects, quick recovery, and less recurrence, which has obvious advantages over traditional surgery. Recently, many patients have been coming to us for treatment of adenoid hypertrophy with low-temperature plasma ablation, and they often ask questions about the perioperative period.
