“…19 Additionally, the depth of NLF was considered as the best single indicator for the assessment of NLF correction by Wang et al, because they found that the most significant change after NLF correction was the depth. 20 In this study, both the GAIS score and MVD were used to illustrate the change in NLFs after HA injection. The results showed that the MVD was positively correlated with the GAIS score, which verified that the MVD could be used as a tool for evaluating the efficacy of correcting NLFs in clinical practice.…”

“…In recent years, three‐dimensional (3D) imaging techniques have gained popularity in the quantitative evaluation of various cosmetic procedures, including facial rejuvenation, rhinoplasty, and breast aesthetics 9–16 . The noninvasive nature, speed, and high accuracy of 3D imaging have made it a valuable tool for assessing the NLF as well 17–21 . However, quantifying the changes in the NLF can be challenging due to its nature as a wrinkle without well‐defined boundaries.…”

Background and ObjectiveThe deepening of the nasolabial fold (NLF) is a common occurrence during the aging process, necessitating the development of an objective method to evaluate changes in NLFs. The objective of our study was to introduce a method of depth deviation based on three‐dimensional (3D) image for evaluating the efficacy of hyaluronic acid (HA) injection in correcting NLFs.MethodsBetween May 2019 and November 2019, we recruited 56 Chinese volunteers with moderate to severe NLFs for this study. The participants received HA injections and were followed up for a period of 12 months. Pre and posttreatment, we collected the Wrinkle Severity Rating Scale (WSRS) scores and 3D images. To assess the efficacy of NLF correction, we used the maximum value of depth deviation (MVD) based on 3D images and the Global Aesthetic Improvement Scale (GAIS) score. Additionally, we compared the relationship between MVD and other clinical parameters.ResultsFifty‐four female participants completed the study and were included in the analysis. The HA injection resulted in a significant decrease in NLF severity (p < 0.05). One month after the injection, the average GAIS score was 4.72 ± 0.45, and the average MVD was 2.10 ± 0.56 mm. Both the GAIS score and the average MVD exhibited a decline over time during the follow‐up period, with the average MVD showing a significant correlation with the GAIS score at all time points (p < 0.05).ConclusionsUsing 3D technology, we demonstrated that the quantitative data provided by MVD can serve as an objective method for evaluating the correction of NLFs.

Background Botulinum toxin-A（BTX-A）is used in the treatment of nasolabial fold (NLF). However, light and clinician subjectivity play a big role in evaluating the efficacy of this treatment. Objectives With the application of three-dimensional (3D) technology, this study aimed to quantitatively evaluate the effects of muscular type (M) and muscle-fat pad mixed-type (MF) NLF with BTX-A injection. Methods BTX-A was injected into the bilateral mark points of the NLF, where the levator labii alaeque nasi(A), zygomaticus minor(B), and zygomaticus major(C) pull the skin to form the NLF (2 U at each injection site). Pretreatment and posttreatment 3D facial images were captured with static and laughing expressions. The curvature, width, depth, and lateral fat volume of the NLF were measured to compare the therapeutic efficacy of patients with type M and MF NLF. Results Thirty-nine patients with type M and 37 with type MF completed the follow-up data. In these patients, the curvature, width, and depth of the NLF showed a significant reduction at 1 month and gradually recovered at three and six months after treatment, with more significant improvement when laughing than when static. Variations compared to the pretreatment values of type MF were greater than those of type M at each time point. The lateral fat volume of the type MF NLF was significantly reduced (P < 0.05). Conclusions Three-dimensional technology can quantitatively evaluate the effects of type M and MF NLF treatments with BTX-A injection. BTX-A has a better effect on the NLF of type MF than that of type M.
