Comparison of tissue effects with sculptured fiberoptic cables and other Nd:YAG laser and argon laser treatments.
The use of a fiber optic cable in contact with tissue results in a complex thermal interaction between the cable and the tissue. The effect of the laser-tissue interaction was investigated using sculptured quartz fiber optic cables, sapphire contact rods, and bare fiber optic cables attached to the Nd:YAG laser. The laser-tissue effects of the Nd:YAG and argon lasers were compared. Examination of treated animals showed there to be a significant difference between immediate and 48-hour thermal effects. The sculptured fibers created significantly less tissue damage than the sapphire contact tips, the 0.6-mm bare fiber, or the argon laser with a 0.3-mm bare fiber either with or without contact. All Nd:YAG laser contact treatments were less damaging than the argon laser treatments.
