Analysis of upper lip appearance after surgical lip augmentation procedure "VY in VY": Progress of results

Many materials and techniques were used for lip augmentation, whereas in the last years all attention is paid for filling material, and long-lasting surgical techniques were ignored.

This study includes 12 candidate patients for upper lip augmentation; all are females, their age range 21-24 years. Standardized anterior and lateral photographs of each subject were taken at: preoperative, 2, 4, and 12 months later, and were analysed using digital imaging software to quantify postoperative changes. We used t-test of correlated samples to detect any statistical significance and Interclass correlation coefficient test (ICC) for reliability that proved the reliability and reproducibility of our method.

there were statistically significant improvements in al parameters that characterize the fullness of the upper lip. These changes was observed from the 2^nd month (P<0.05) and continued improving until the 4^th month (P<0.05), after that they appeared to be stable (P>0.05). These changes were at the 12^th month postoperative in: upper white lip (-9%), upper red lip (53%), upper red lip area (63%), protrusion (41%) and nasolabial angle (-7%). There was no statistical significance in the change of Cupid's bow curvature (P-value = 0.104 > 0.05).

VY in VY for upper lip augmentation improves the parameters that define the youthful and fully appearance of the upper lip and the progress of results may be predictable. These improvements appear to be stable from the 4th month. Also, it doesn't change the Cupid's bow curvature.
