Abstract
The authors investigated the surgical and collateral effects on soft tissue of a carbon dioxide laser emitting at 9.3 micrometers. Specifically, incision widths and depths as well as effectiveness were studied. Three different laser modes were investigated: gated continuous wave, or Cw, Superpulse and OptiPulse (Medical Optics). Incision depths correlated positively with average power; higher powers produced deeper incisions. The gated Cw mode quickly produced wide, deep incisions; Superpulse achieved narrower, deep incisions; OptiPulse caused very narrow, shallow incisions. Collateral damage to adjacent tissues was reduced by a factor of about 2 using Superpulse, and by a factor of 10 using OptiPulse. A wide range of effects is achieved in soft tissue, depending on the laser parameter combination used.

Summary
Title Investigating the range of surgical effects on soft tissue produced by a carbon dioxide laser. The authors Investigated the surgical and collateral effects on soft tissue of a carbon dioxide laser emitting at 9.3 micrometers. The gated Cw mode quickly produced wide, deep Incisions; Superpulse achieved narrower, deep incisions; OptiPulse caused very narrow, shallow incisions. A wide range of effects is achieved In soft tissue, depending on the laser parameter combination used. Many areas of routine C02 laser use for soft-tissue surgery have developed during the past 30 years, including orofacial surgery and periodontal applications Advantages of this tool include precision, minimal intraoperative hemorrhage, sterilization of the surgical area and healing with minimal scarring, postoperative pain and swelling.[15] The clinician should be able to predict and achieve specific incisional or ablational effects.
