Analysis of the complementary measurement of nasogenian wrinkles using Radiocef 2.0® software in the evaluation of facial chronoaging among women of different age groups

Abstract

Objective : To evaluate the facial aging of women of different ages using a software program to assist in the classification of wrinkles and sagging in the nasogenian region. Method : A descriptive observational study of 100 female volunteers was performed. The women were aged between 20 and 70 years old and were sorted by age group into five groups of 20 volunteers each. The instruments used were the Facial Assessment Protocol, a cephalostat for the standardization of photos, a 14.1 megapixel Sony digital camera, and the Radiocef 2.0® software program. The Kolmogorov-Smirnov (KS) test was used for confirmation of normality and all data was statistically analyzed using ANOVA and Tukey's post hoc analysis. The Chi-squared and Pearson's correlation tests were also performed. A significance level of 5% and a p value of ≤0.05 were adopted. Results : It was observed that all age groups had wrinkles in the nasolabial fold region. There was an association between age and the Goglau, Lapiere and Pierard scale. This incidence increased progressively with aging. A moderate correlation (r=0.67) was observed between age and distance from the nasolabial folds, while angle represented only a weak correlation (r=0.3), with the most significant age group that with the shortest distance and the widest angle. Conclusion : The present study demonstrated the importance of the Radiocef 2.0® software program in providing a more detailed analysis of the nasolabial folds. It is therefore a complementary assessment to the Facial Assessment Protocol, representing a research protocol for identifying the effectiveness of treatments and improving the evaluative procedure.
