Background: Currently, the Wallace Rule of Nines is the most widely used method to measure total body surface area (TBSA) in burned patients due to its practicality and speed in its application; however, it often provides inaccurate estimations in obese patients, affecting the fluid resuscitation process.
Objective: In this study, we aimed to modify and optimize the Rule of Nines' values for its application in these patients.
Methods: We compared the estimations of the TBSA established by the Wallace Rule of Nines against the measurements of the three-dimensional (3D) software Skanect - Meshmixer 3.
