RESUMEN
BACKGROUND: CO2 resurfacing and CO2 microfractionated laser systems are reliable tools to improve different facial pathologic skin conditions but are associated with a high rate of complications specially in Fitzpatrick III, IV, and V skin phototypes, predominant in the Latin population, which has pushed many surgeons to change technologies and abandon its use. OBJECTIVE: To compare patient results with the CO2 resurfacing laser and microfractionated CO2 laser resurfacing in all skin types and show similar results to those obtained worldwide in patients with phototypes III, IV, and V. METHODS: Standardized review of medical records from a database of private practice patients treated since January 1998 to July 2012 with SlimE30 MiXto SX(®) CO2 laser. Evaluation of outcomes, complications, and satisfaction of three different modalities of treatment (CO2 ablative laser, CO2 microfractionated and a combination of both) was made. RESULTS: A total of 665 treated patients were included. Ablative CO2 was applied to 80.3 %, CO2 microfractionated to 15.1 %, and mixed treatment to 4.5 % of cases. Globally, hyperpigmentation rates were 30.4 % in the CO2 resurfacing group, 16.3 % when a combination of modalities was applied and 11 % in microfractionated CO2 cases. A steady increase of these rates is shown as the phototype becomes higher. Satisfaction rates were high for all groups: 86.7 % in the mixed group, 82.2 % in the microfractionated CO2, and 79.6 % in the CO2 ablative. CONCLUSIONS: Good results and an acceptable rate of complications in latin skins are obtainable after treating patients with CO2 ablative and microfractionated CO2 systems alone or in combination. Staged treatments and adequate post-procedure care reduce these complications.
