Clinical advantage of the CO2 laser superpulsed mode. Treatment of verruca vulgaris, seborrheic keratoses, lentigines, and actinic cheilitis.

摘要: background. Unintended thermal damage occurring during surgery with the CO2 laser limits its usefulness because of slow healing and increased scarring. The superpulsed mode was developed to address this problem, but little clinical data exist evaluate effectiveness. objective. Patients having warts hands feet, seborrheic keratoses, lentigines, actinic cheilitis were treated by three experienced surgeons using both conventional continuous a laser. Effectiveness therapy, time, rates scarring compared for two groups patients. methods. Charts patients in 1988 1989 reviewed recorded regarding surgical parameters, scarring, effectiveness therapy. placed diagnosis category each only if there corresponding patient same physician other laser. conclusion. found convey slight advantage. use 50-millisecond pulse even more advantageous. superpulse parameters are analyzed ideal prevent unwanted suggested.
