Comparação de três técnicas de medidas de volume mamário: método universal para mastoplastia, ressonância magnética e crisalix 3d software®

Abstract

The measurement of breast volume is important to obtain satisfactory results in breast surgeries. There are many techniques that are proposed for this purpose. Thus, the aim of the present study is to compare 3 techniques for measuring breast volume. Twenty eight (28) breasts (Fourteen (14) patients) were selected from the preoperative list of the Plastic Surgery outpatient clinic SCPMR with an indication for mastoplasty. Three techniques for measuring breast volume were compared: The Universal Method for Mastoplasty, Magnetic resonance imaging (MRI) and Crisalix 3d software® . The volume measurements were tabulated and analyzed using the R software. The mean age was 30.93 ± 10.25 years. The mean breast volume by the MRI technique (considered the gold standard) was 1,554.54 ± 512.54 cm3, by the Crisalix 3d software® technique it was 1,199.64 ± 403.13 cm3 and 1,518.04 ± 468.72 cm3 by The Universal Method for Mastoplasty. Comparing the Crisalix 3d software® and MRI techniques, the paired t-test showed that there was a statistically significant difference between them (t = 4.3957, df = 27, p-value = 0.0001543). Comparing the single labeling and MRI techniques, the paired t-test showed that there was no statistically significant difference between them (t = 1.3841, df = 27, p-value = 0.1777). In comparison with MRI, measurement of breast volume by The Universal Method for Mastoplasty did not show a statistically significant difference between these two techniques. However, the Crisalix 3d software® technique showed a difference in relation to the MRI. Anthropometric measurements are useful for measuring breast volume and, due to their ease, practicality and low cost, they should be part of the plastic surgeon's arsenal.
