ABSTRACT
Arguably the major advantage of the ultrasonically activated instrument is the smaller lateral thermal injury compared to the electrocautery. It has been demonstrated that the lateral thermal injury caused by the HS is 0-1000 mm compared to 240 mm to 15mm by the electrocautery (8). However, since no significant neurovascular bundle is present in the immediate vicinity of the dissection area, this advantage of the HS is not of great significance in tonsillectomy.
