Cutaneous Resurfacing with CO2 and Erbium: YAG Lasers: Preoperative, Intraoperative, and Postoperative Considerations

TLDR

Pulsed and scanned CO₂ and erbium:YAG lasers have transformed cutaneous resurfacing by delivering high‑peak fluences for precise tissue vaporization while limiting thermal damage, with their differing ablation depths and coagulation profiles guiding patient selection. The article reviews the fundamental principles of CO₂ and erbium:YAG laser resurfacing, covering pre‑, intra‑, and postoperative patient considerations, and briefly outlines future research directions. It summarizes the basic operational concepts of these lasers and provides specific guidelines for managing the side‑effects and complications that arise during resurfacing. The review offers practical recommendations for the prevention and treatment of common post‑laser complications, such as erythema, edema, and infection.

Abstract

The development and integration of pulsed and scanned CO2 and erbium:YAG laser systems into mainstream surgical practice over the past years has revolutionized cutaneous resurfacing. These lasers are capable of delivering to skin high peak fluences to effect controlled tissue vaporization, while leaving an acceptably narrow zone of residual thermal damage. The inherent technological differences that exist between the two distant laser systems in terms of ablation depths, degree of thermal coagulation, and postoperative side-effects and complications guide patient selection and management. This article reviews the basic principles of CO2 and erbium:YAG laser resurfacing, including preoperative, intraoperative, and postoperative patient considerations. Side-effects and complications encountered after laser resurfacing are discussed with specific guidelines provided on their appropriate management. Anticipated future developments and cutting-edge research endeavors in cutaneous laser resurfacing are also briefly outlined.
