Abstract—Geometric morphometric tools were used toanalyze the shape of the faces of 84 hypertensive and nonhypertensivemales. Image analysis was done on the fortyone (41) landmarks of the face. Landmarking was done inthree replicates making sure that one session is well spacedfrom another to minimize bias. The pooled data were fedinto the SAGE program, which performed PrincipalComponent Analysis, Analysis of Variance (ANOVA) andProcrustes Fit. Results revealed a higher fluctuatingasymmetry in hypertensive male subjects compared to thenon-hypertensives. This is further supported by thedifferences shown by scatterplot analysis.
