ABSTRACT

Background: Endolaser subdermal technique applied in aesthetic treatments, has a wide range of uses and approaches different body and face areas. Current literature shows a significant lack of dosimetric standardization regarding subdermal laser use for treating aesthetic disorders. Objective: This study aimed to describe the fundamentals that guide dosimetric parameters adoption considered safe and effective for endolaser use in such treatments. Material and Methods: This study is characterized by exploratory research, presented through a narrative review to highlight the foundations and criteria for an appropriate use of dosimetric parameters while performing endolaser technique. Besides literature review, data regarding a specific method for choosing doses related to the energy accumulation were added. Such method was exclusively developed in Brazil by the authors. Results and Discussion: We verified that the dosimetric parameters used, with power (Watts), continuous or pulsed mode of laser emission are extremely important for effectiveness and safety of the method, as well as the total energy accumulated to generate the necessary therapeutic heat in the target area. Therefore, authors established a way of customizing the dosimetry through mathematical calculations based on the physical characteristics of treated region and a specific energy dosimetric range. Thus, we can choose customized, effective and safe doses of subdermal laser in each clinical situation. However, these doses may be higher when the thickness of the adipose tissue is greater than 3 cm. Conclusion: Finally, endolaser must be parameterized based on the physical characteristics of each target area to be treated. Adoption of customized dosimetric strategies is necessary to assure safe and effective results.
