Abstract
We describe our experience with 2 new techniques for tonsil and adenoid reduction after experience with 150 procedures. Both techniques are based on low-temperature radiofrequency energy to reduce tonsil and adenoid size rather than excision of tonsil or adenoid tissue. The advantages are almost complete elimination of pain and postoperative bleeding risk. Tonsil ablation is performed by applying radiofrequency energy to the tonsil tissue, which causes posttreatment shrinkage and scarring. Tonsil coblation is based on tonsil reduction by surface application radiofrequency until 90% of the tonsil is eliminated. The disadvantage is that both procedures do not accomplish complete tonsillectomy and some residual tonsillar tissue is left. With tonsil ablation, approximately 40% of the tonsil remains, whereas with tonsil coblation, only 10% of the tonsil remains. Tonsil coblation is more predictable because the surgeon controls the amount of reduction at the time of surgery. Both procedures result in minimal pain, and over 90% of the patients resume a solid diet within 48 hours.
