- Abstract
BACKGROUND. <em>Unintended thermal damage occurring during surgery with the</em> CO2 <em>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 to evaluate its effectiveness.</em> OBJECTIVE. <em>Patients having warts of the hands and feet, seborrheic keratoses, lentigines, and actinic cheilitis were treated by three experienced laser surgeons using both the conventional continuous mode</em> CO2 <em>laser and a superpulsed</em> CO2 <em>laser. Effectiveness of therapy, healing time, and rates of scarring were compared for the two groups of patients.</em> METHODS. <em>Charts of patients treated in 1988 and 1989 were reviewed and data recorded regarding surgical parameters, healing time, scarring, and effectiveness of therapy. Patients were placed in a diagnosis category with each laser only if there was a corresponding patient treated by the same physician using the other laser.</em> CONCLUSION. <em>The superpulsed mode was found to convey only a slight advantage. The use of a 50-millisecond pulse was even more advantageous. The superpulse parameters are analyzed and ideal parameters to prevent unwanted thermal damage are suggested.</em>
