Safety And Efficacy Of Princess® FILLER Lidocaine In The Correction Of Nasolabial Folds

Social Profiloplasty:A Practical Assessment and Injection Guide

The trend of aesthetic medical procedures continues growing every year since decades all over the globe, especially considering minimal invasive treatments since the results are immediate and the downtime minimal. Hence, treatments with hyaluronic acid fillers have become extremely popular and routinely used in common practice. However, numerous areas of treatment were identified and described in the last years clinical training and consciousness of possibly complication remain still under represented. In the following article, we present four key treatment areas for optimal overall facial rejuvenation of what the authors define the social profile. Of each area an assessment, anatomical considerations, danger zones and the preferred personal technique of the authors are described.

Monophasic and Biphasic Hyaluronic Acid Fillers for Esthetic Correction of Nasolabial Folds: A Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Hyaluronic acid (HA) fillers have become the most popular dermal fillers for esthetic nasolabial folds (NLFs) correction. Based on the cross-linking method, they can be classified as monophasic or biphasic types.

OBJECTIVES

The aim of this meta-analysis is to compare the efficacy and safety of monophasic HA fillers with that of biphasic HA fillers for treatment of NLFs. PubMed, Embase, Cochrane Library, Web of Science, ClinicalTrials.gov, and Chinese databases were searched from inception to January 2021.

METHODS

Randomized controlled trials (RCTs) that compared treatment outcomes of a monophasic HA filler with a biphasic HA filler for esthetic NLF correction were selected. Twenty-two RCTs with totally 1848 subjects were included to this meta-analysis. A significantly higher improvement of NLF severity score was seen for monophasic fillers than biphasic fillers at 2 (p = 0.005), 8 (p <0.0001), 12 (p = 0.03), 16 (p = 0.005), 24 (p <0.00001), 36 (p = 0.007), and 52 week (p <0.0001) after treatment.

RESULTS

The effect was retained regardless of ethnicity, total injection volume, and baseline NLF severity. More subjects preferred monophasic fillers over biphasic ones (≤7 months: RR = 3.45, 95% CI 1.17 to 10.11; >7 months: RR = 2.37, 95% CI 1.45 to 3.86). Rate of post-injection pain was significantly lower for monophasic fillers (RR = 0.85, 95% CI 0.78 to 0.92, p <0.0001), but no statistical difference was observed for other post-injection adverse events. Compared to biphasic HA fillers, monophasic HA fillers were associated with a greater and more durable esthetic NLFs improvement, a lower rate of post-injection pain, and were favored by more patients.

The Impact of Dermal Fillers on Perceived Personality Traits and Attractiveness

BACKGROUND

Dermal fillers are increasingly popular for facial rejuvenation and enhancement, including effacement of nasolabial folds (NLFs) and marionette lines and lip augmentation. This study aimed to evaluate casual observer perception of physical and interpersonal traits of subjects who receive filler treatment.

METHODS

An anonymous survey of 8 before/after treatment photographical sets was administered in Likert scale format (1-7) using online crowdsourcing. Three sets of photographs were before/after NLF/ marionette line treatment, three of lip augmentation, and two internal controls. Respondents were surveyed on personal demographics, as well as perceptions of subject photographs across nine domains (facial symmetry, confidence, likeability, youthfulness, trustworthiness, attractiveness, intelligence, approachability, happiness).

RESULTS

In total, 260 respondents completed the survey. The majority were male (63.1%), Caucasian (58.1%), 18-34 years old (58.1%), and college graduates (66.2%). Respondents rated photographs with line filler treatment and lip filler treatment as significantly improved compared to the pre-treatment photographs across all nine trait domains [p < 0.001, for all]. No differences were found between the control photosets [p > 0.05, for all]. Middle-aged respondents (35-55 years) were more likely to perceive treated filler photographs as more youthful than younger respondents (18-34 years) [p < 0.006] Additionally, respondents with lower educational attainment (high-school graduate or less) were more likely to perceive treated patients as less intelligent compared to higher-educated respondents (college/postgraduates) [p < 0.05, for both].

CONCLUSION

The use of dermal fillers for treatment of NLF/marionette lines and lip augmentation have significant associations with the perception of improved attractiveness and several personality traits. Additionally, casual observer demographic subgroups may influence perceptions.

Two Randomized Controlled Trials of Hyaluronic Acid Fillers for the Correction of Nasolabial Folds

YVOIRE Classic s (YC) and Restylane (RES) have similar rheological properties, which suit mid-dermis injection, while the rheological properties of YVOIRE Volume s (YV) are comparable to those of Perlane (PER), which suit deep dermis injection to treat deep wrinkles. Two similarly designed studies aimed to evaluate the performance and safety of YC and YV injected into the nasolabial folds (NLFs).

METHODS

These were split-face designed, evaluator-blind, noninferiority studies. Fifty-eight subjects with moderate-to-severe NLFs were enrolled in the first study and treated with YC and RES, and 57 subjects were enrolled in the second study and treated with YV and PER. The Wrinkle Severity Rating Scale ranged from 1 (no visible fold) to 5 (extremely deep and long folds), and subject satisfaction was evaluated.

RESULTS

The least squares mean Wrinkle Severity Rating Scale scores (standard error) at week 26 were 2.56 (0.09) for both YC- and RES-treated NLFs and 2.89 (0.08) and 2.91 (0.08) for YV- and PER-treated NLFs, respectively. The difference between the groups was 0 and 0.02, and the lower limit of its 95% confidence interval was -0.0725 and -0.0125, which was greater than the predefined margin (-0.29), proving the noninferiority of YC and YV to RES and PER, respectively. The safety profiles and subject satisfaction of YC and YV were similar to those of RES and PER, respectively.

CONCLUSION

YC is comparable to RES and YV is comparable to PER in terms of performance and safety profiles, with NLF-correcting effects lasting for up to 26 weeks.

J, Yang H, Kwon H, Lee S, Lim HS, Lim SY, Oh C. Heights and spatial relationships of the facial muscles acting on the nasolabial fold by dissection and three-dimensional microcomputed tomography

The aim of this study was to clarify the heights and spatial relationships of the facial muscles acting on the nasolabial fold (NLF) by dissection and three-dimensional microcomputed tomography for use in aesthetic treatments. This study used 56 specimens from 34 embalmed adult Korean. A reference line (RF) was set to imitate the NLF after removing the skin, from the superior point of the alar facial crease to the lateral point of the orbicularis oris muscle at the level of the corner of the mouth. The heights and spatial relationships of the facial muscles along the RF could be categorized into five main patterns. The dominant pattern was that the levator labii superioris alaeque nasi muscle (LLSAN), levator labii superioris muscle (LLS), zygomaticus minor muscle (Zmi), and zygomaticus major muscle (Zmj) were on the medial third, medial half, middle third, and lateral third of the RF, respectively. In micro-CT imaging, beneath the skin of the medial half of the NLF, the LLSAN and Zmi fibers inserted into the dermis of the NLF and adjacent to the NLF. Beneath the skin of the middle third of the NLF, the Zmi fibers were found before the muscle inserted into the dermis of the NLF and adjacent to the NLF. Beneath the skin of the lateral third of the NLF, the lateral margin of the orbicularis oris muscle and some Zmj fibers were found at the location of the NLF. The present study utilized dissections and micro-CT to reveal the general pattern and variations of heights and spatial relationships of the facial muscles passing beneath the NLF. These findings will be useful for understanding which muscles affect specific parts of NLFs with various contours, for reducing the NLF in aesthetic treatments, and for reconstructing the NLF in cases of facial paralysis.
