Quantificação da deformidade dinâmica após implante mamário em duplo plano através de medidas antropométricas lineares

Abstract

Background: Dynamic breast is a known entity characterized by visible distortion and deformity of the breast as a result of the contraction of the pectoralis major muscle after a subpectoral implant, fortunate occurring in small fraction of the patients. The purpose of this study is to present an original method for objectively measuring the breast distortion on patients submitted to dual plane augmentation. Methods: We studied 32 female patients, aged 18 – 50 years, who underwent primary dual plane breast augmentation with at least one year of follow-up. Anthropometric landmarks in the breast region were marked as parameters in order to originate linear segments. Through the study of photographs of the breast region, taken under no contraction and under maximum contraction of the pectoralis muscle (MCP), measurements of the linear segments were made through the use of a software, and comparisons between the measured groups were evaluated. Results: We found differences in all the segments analyzed when comparing the measurements of the breasts under no contraction of the pectoralis muscle and under MPC (p<0,001). Conclusion: Our study proposes a new and original method for measuring the dynamic breast distortion after dual plane augmentation through photogrammetry, allowing us not only to quantify the deformity but also to reproduce this methodology in any patient, contributing to objective enlightenment, for surgeons as well as patients, regarding this entity, not unusual after subpectoral implant.
