They were evaluated with a standart protocol. The post operative pain were graduated through the horizontal visual scale analogue. RESULTS: Surgical time were shorter with the ultrassonic thecnique compared to the traditional cold instruments. The amount of stitch at tonsilar fossa was lesser than the traditional thecnique.
