Evaluation of the simulation effectiveness of prosthetic breast augmentation with Vectra 3D system / 中华整形外科杂志

ABSTRACT

Objective@#To evaluate the accuracy of the simulation with a 3D stereophotogrammetric imaging system(Vectra) for the prosthetic breast augmentation.@*Methods@#From July 2014 to December 2015, 32 patients received Vectra scanning prior to breast augmentation. The simulations of post-operation images were created by the software.The distance of SN-N line, N-N line and the volume of the simulated breast was measured by the software. The patients came back for a follow-up 1-6 months post-operation. At that time, the same type of data was collected again, and the difference of simulated and real post-operation breast was calculated. 18 professional doctors scored the accuracy of the simulation using a 1-10 scale. We defined 6-10 as"of great accuracy". The scores were analyzed using the independent-sample t test.@*Results@#The simulated distance of SN-N line(L/R), N-N line(L/R) and the volume(L/R) was (19.3±1.4) cm/(19.3±1.2) cm、(19.0±1.5) cm and (369.0±64.5) ml/(370.0±82.7) ml. The real distance of SN-N line(L/R), N-N line(L/R) and the volume(L/R) was (19.0±1.3) cm /(19.0±1.2) cm、(18.4±1.3) cm and (365.6±81.0) ml/(360.2±84.2) ml. Those data of simulating and real post-operation breast was statistically insignificant (P>0.05). The score of the simulation accuracy by 18 professional doctors was 7.9±1.4, which means the doctors agreed the accuracy of Vectra for the breast augment simulation was great.@*Conclusions@#The Vectra can simulate the figure of breast augmentation with good accuracy.
