Abstract
Background Soft-tissue fillers, specifically hyaluronic acid fillers, can reduce many signs of aging by treating the associated loss of subcutaneous fat and midfacial contour deficiencies. The objective of this study was to investigate whether the effectiveness and safety of Belotero Volume Lidocaine (BVL) compared with Restylane (RES, control) is noninferior in the treatment of severe nasolabial folds (NLFs) in Chinese patients. Methods This was a prospective, randomized, controlled, split-face clinical study. Overall, 220 Chinese patients of both sexes with symmetrical NLFs of severe intensity (grade 4) on the Wrinkle Severity Rating Scale (WSRS) were treated with both fillers. Treatment outcomes were assessed by the WSRS, and other scales, at multiple time points up to 18 months postinjection. The co-primary effectiveness outcomes were based on the blinded evaluator ratings of NLFs according to the WSRS scale after 6 and 12 months. Adverse events were assessed during the whole study and patients' pain sensation at three time points after injection. Results Noninferiority of BVL versus control based on the WSRS was demonstrated at month 6 and month 12. Response rates were slightly higher for BVL than control at all time points, and BVL had a sustained effect until month 18. Pain sensation scores were significantly lower for BVL compared with control. The incidence rates of treatment-related AEs were low and very similar for both treatments. Conclusions This study demonstrates that BVL is a safe, long-lasting, and effective treatment to correct severe NLFs in Chinese patients while being noninferior to the control device.

A Multicenter Noninferiority Study Comparing Safety and Effectiveness of Hyaluronic Acid Fillers for Correction of Nasolabial Folds in Chinese Subjects. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e4810. [PMID: 36845861 PMCID: PMC9945413 DOI: 10.1097/gox.0000000000004810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 12/16/2022] [Indexed: 02/23/2023]
Abstract
Hyaluronic acid fillers are the preferred choice for minimally invasive facial volume restoration. In this study, a split-face design was used to compare the effectiveness and safety results of Belotero Balance Lidocaine (BEL) and Restylane (RES, control) to investigate whether BEL is noninferior compared with RES in nasolabial fold (NLF) correction. Methods This was a prospective, controlled clinical study in Chinese subjects. Subjects with symmetrical moderate NLFs according to the Wrinkle Severity Rating Scale were randomized to receive BEL in one NLF and RES in the other. The primary objective was to investigate whether BEL is noninferior compared with RES after being injected mid-dermally in moderate NLFs after 6 months. Secondary objectives included responses at other visits and pain sensation. Treatment-emergent adverse events (TEAEs) were assessed. Results A total of 220 subjects were enrolled. The Wrinkle Severity Rating Scale response rates at month 6 were 62.9% for BEL versus 64.9% for RES, demonstrating noninferiority. The secondary endpoints supported this. Significantly reduced pain scores were observed for BEL versus RES. For both products, injection site nodule and bruising were the most frequent treatment-emergent adverse events at the injection site. All treatment-related treatment-emergent adverse events were mild. Conclusions The study showed that BEL is effective and well tolerated for correction of moderate NLFs in Chinese subjects. Noninferiority of BEL was demonstrated compared with RES, and regardless of applied pain treatment, a further reduction in injection pain was observed in BEL.

Abstract
BACKGROUND Soft-tissue augmentation of the midface is increasingly requested by patients, and hyaluronic acid (HA) fillers are frequently used in treatment. AIMS To evaluate the efficacy and safety of treatment of midface volume/contour deficit with a firm HA filler including lidocaine (HARL ). PATIENTS/METHODS This was a 12-month, randomized, evaluator-blinded, controlled study. Chinese adults with mild to substantial volume loss were randomly assigned in a 3:1 ratio to treatment or untreated control groups. RESULTS A total of 148 subjects were enrolled. The primary objective was met; results of the midface volume scale (MMVS) rated by a blinded evaluator were in favor of HARL at Month 6 (p < 0.0001 vs. the untreated control group). Similar to the MMVS improvement, improved midface fullness and aesthetic appearance was observed based on the Global Aesthetic Improvement Scale (GAIS) up to 12 months by both treating investigators and subjects (at least 96% at Week 4 and 65% at Month 12). Subject satisfaction was high, and the majority of subjects considered the results to look natural (>97%). The study product was well tolerated. CONCLUSIONS Midfacial treatment using HARL was effective, well tolerated, and led to high levels of satisfaction in a Chinese population for up to 12 months.

Abstract
Abstract Tissue fillers injections remain to be one of the most commonly performed cosmetic procedures. The aim of this meta-analysis was to systematize and present available data on the aesthetic outcomes and safety of treating the nasolabial fold area with tissue fillers. We conducted a systematic review of randomized clinical trials that report outcomes concerning treatment of nasolabial fold area with tissue fillers. We searched the MEDLINE/PubMed, ScienceDirect, EMBASE, BIOSIS, SciELO, Scopus, Cochrane Controlled Register of Trials, CNKI and Web of Science databases. Primary outcomes included aesthetic improvement measured using the Wrinkle Severity Rating Scale score and Global Aesthetic Improvement Scale. Secondary outcomes were incidence rates of complications occurring after the procedure. At baseline, the pooled mean WSRS score was 3.23 (95% CI: 3.20–3.26). One month after the procedure, the pooled WSRS score had reached 1.79 (95% CI: 1.74–1.83). After six months it was 2.02 (95% CI: 1.99–2.05) and after 12 months it was 2.46 (95% CI: 2.4–2.52). One month after the procedure, the pooled GAIS score had reached 2.21 (95% CI: 2.14–2.28). After six months, it was 2.32 (95% CI: 2.26–2.37), and after 12 months, it was 1.27 (95% CI: 1.12–1.42). Overall, the pooled incidence of all complications was 0.58 (95% CI: 0.46–0.7). Most common included lumpiness (43%), tenderness (41%), swelling (34%) and bruising (29%). Tissue fillers used for nasolabial fold area treatment allow achieving a satisfying and sustainable improvement. Most common complications include tenderness, lumpiness, swelling, and bruising.

Abstract
BACKGROUND Hyaluronic acid (HA) dermal filler injection is believed to be a safe procedure. However, with the increase in the number of performed procedures and indications, the number of product-related complications, especially delayed inflammatory reactions, has also increased. Delayed-type hypersensitivity (DTH) reaction is one of these delayed inflammatory reactions, which is preventable by performing a pretreatment skin test. OBJECTIVES The authors sought to find the incidence of delayed inflammatory reactions and DTH reaction after HA injection and to determine whether a pretreatment skin test is worthwhile to be performed. METHODS The authors conducted a systematic literature review of all the relevant prospective studies, retrospective studies, and case reports on delayed inflammatory reactions and DTH reaction after HA filler injection. RESULTS The incidence of delayed inflammatory reactions calculated from the prospective studies was 1.1% per year, and that of possible DTH reaction was 0.06% per year. Most retrospective studies estimated a percentage of delayed inflammatory reactions of less than 1% in 1 to 5.5 years. The incidence of DTH reaction would be lower than that. Among all the DTH cases reported, only about 5% of them were proven to be genuine DTH reactions. CONCLUSIONS The incidence of both delayed inflammatory reactions and DTH reaction is low. There is evidence that genuine DTH reactions caused by HA fillers approved by the Food and Drug Administration do exist. This adverse event can be prevented by performing a pretreatment skin test. However, the incidence of DTH reaction is so low that the pretreatment skin test is not mandatory if Food and Drug Administration-approved HA fillers are used. LEVEL OF EVIDENCE: 4

Abstract
BACKGROUND Hyaluronic acid (HA) gel is a widely used dermal filler for the correction facial volume loss. The incorporation of lidocaine with HA provides a pain-relieving alternative for individuals considering facial rejuvenation. The aim of this systematic review and meta-analysis is to compare the effectiveness and safety of HA with lidocaine (HAL) with that of HA without lidocaine for the treatment of nasolabial folds (NLFs). METHODS Studies were identified using the electronic databases PubMed, Embase, Cochrane Central Register of Controlled Trials and Web of Science from inception up to January 2018. Randomized controlled trials (RCTs) were selected based on the inclusion criteria. Outcomes included 100-mm Visual Analogue Scale (VAS) score, Wrinkle Severity Rating Scale score and adverse events. RESULTS A total of 908 patients from 12 RCTs were included in the meta-analysis. VAS score within 30 min after injection in the HAL group was much lower than that with just HA group (MD = - 28.83, 95% CI - 36.38 to - 21.28). There was no significant difference in effectiveness between the two products 24 months post-injection (MD = 0.13, 95% CI - 0.15 to 0.41). The main adverse events, such as swelling, erythema, bruising, itching and induration, also showed no significant difference. CONCLUSIONS HAL is more effective for pain relief than HA alone, but both display similar effectiveness and safety for the correction of NLFs.

Abstract
BACKGROUND Rhinoplasty has traditionally been preferred for correction of nasal defects. Long-term clinical experience with hyaluronic acid (HA) injection as an alternative or complement to rhinoplasty is presented. METHODS A retrospective review of the author's clinical experience with HA gel for nasal reshaping from 1997 to 2012 was conducted, with treatments performed during 1998, 2005, and 2012 selected for detailed review. RESULTS More than 250 patients were treated for nasal reshaping with HA since 1997. In addition to being a complement to surgery, HA injection successfully addressed nasal defects that would have been difficult to correct surgically. The effect persisted for >1 year in most patients (>5 y in some patients), with individual variations. No serious complications occurred. When comparing the 3 years reviewed in detail, new indications for nasal reshaping with HA gel became evident over time, which was also reflected by the increase in number of patients treated (1998: n = 2; 2005: n = 22; 2012: n = 51). Of these patients, 55 (73%) received HA injection instead of rhinoplasty, 20 (27%) received HA injection after rhinoplasty, and 5 (7%) underwent rhinoplasty after HA injection. The mean injection volume was 0.4 mL HA gel/treatment. All patients were satisfied with the primary outcome of treatment. Retreatment was performed in 32 patients (43%). CONCLUSIONS Injection of HA gel is a valuable tool for nasal reshaping. It can also be used for correction of minor postrhinoplasty defects in appropriate patients.

Abstract
INTRODUCTION In esthetic treatments with dermal fillers, increasing numbers of physicians are using the technique of mixing an anesthetic agent into the dermal filler before treatment to increase the comfort of the patients. This study aimed at evaluating the effects on the physical properties of a polycaprolactone (PCL)-based dermal filler after mixing with lidocaine. METHODS A range of 2.0% lidocaine and 2.0% lidocaine/epinephrine concentrations was mixed with the PCL dermal filler to evaluate the changes in dynamic viscosity and elasticity, extrusion force, pH, and needle jam rates. The number of passes back to forth for optimal homogeneity of lidocaine and PCL dermal filler was determined. RESULTS With 15 mixing strokes the lidocaine solution can effectively be mixed into dermal filler resulting in a homogenous blend. The viscosity, elasticity, and the extrusion force decrease with increasing lidocaine volume. The viscosity and elasticity of the dermal filler is sufficient to keep the PCL microspheres in suspension. There were no needle jams. The pH of the PCL dermal filler mixed with lidocaine solution is equivalent to that of the original dermal filler. CONCLUSION It is concluded that mixing of lidocaine into the PCL-based dermal filler can safely be performed without harmful changes in the physical properties of the original dermal filler.
