In Vitro Comparison

AbstractThis study compares the relative thermal damage caused by a surgical CO2 laser and the Erbium: YAG laser when used to incise the human vocal fold in vitro. Results show that charring is completely eliminated when using the Erbium: YAG laser. The depth of coagulative necrosis adjacent to an incision is reduced from 510 ±m(µ 75) using the CO2 laser to 23 ±m(µ 12) using the Ebrium: YAG laser and at the base is reduced from 125 ±m (µ 45) using the CO2 laser to 12 ±m (µ 8 ) using the Erbium: YAG laser. The potential advantages regarding post-operative healing after laryngeal surgery are discussed.

Heat Transport Capability

In a self-cooled drill, an especially designed bur is used to transport heat generated at the cutting edge into the handpiece, where it is dissipated into an air heat sink. The bur contains a sealed cavity partially filled with water, which transports heat via the principle of rotating heat pipe technology. The heat transport capability of burs fitted out as rotating heat pipes was established. A conceptual design for a representative bur was prepared, based on surgical drill sculpting criteria. It appears that a self-cooled surgical drill for sculpting can limit bone temperatures below levels for the initiation of thermal damage in bone, nerve, and brain tissue, without the need to employ an externally applied coolant.
