Abstract

In the otolaryngological field, SonoSurgR (Ultrasonic Surgical System, developed by Olympus Corporation in Japan) has never been used because the shape of the tips is too large for ENT-Head and Neck Surgery use. SonoSurgR is an ultrasonic surgical device with 47000 Hz vibration and 75 μm amplitude. An ultrasonic vibration at the tip of the SonoSurgR blade can cut the tissue continuously with low tissue damage. SonoSurgR has hemostasis and coagulation performance by frictional heat on the side of the blade. Coagulation will finish with a low temperature, less than 80 °C, and causes few lateral tissue damages. In this paper, we presented the advantages and disadvantages of a SonoSurgR knife blade and a spatula blade that we newly developed for tonsillectomy and nasal conchotomy. SonoSurgR needs no protective glasses, has strong stop-bleeding and high-coagulation ability, has few lateral tissue damage, and has no muscle twitch. Fine SonoSurgR blades with 3.8 mm diameter as newly developed by us are more useful for our ENT-Head and Neck Surgical field surgery. SonoSurgR has a few disadvantages in that the blades are somewhat costly and the sheath heats up with continuous use.
