[BACKGROUND] The degree of modification (MoD) of hyaluronic acid (HA) fillers reflects the extent of chemical cross-linking of native HA chains. Lower MoD values correspond to reduced cross-linker content and potentially more physiological …

[BACKGROUND] Nasolabial folds (NLFs) are a hallmark of facial ageing, and precise correction requires detailed anatomical and vascular mapping. High-resolution ultrasound offers real-time visualisation of soft-tissue layers, filler distribu…

[BACKGROUND] Aging leads to noticeable changes in lip volume, definition, and projection largely due to alterations in the orbicularis oris muscle. Although superficial signs of aging are well-documented, deeper muscular changes remain unde…

This narrative review explores the various injection techniques utilized in facial filler procedures, emphasizing their applications, benefits, and potential complications. The increasing demand for total facial contouring and rejuvenation …

Minimising facial adiposity is a growing esthetic concern for individuals seeking a slimmer facial appearance. While various surgical and nonsurgical approaches have been used, innovative methods for noninvasive facial contouring continue t…

Height augmentation and cephalic contouring using hyaluronic acid (HA) fillers represent an innovative approach in minimally invasive aesthetic medicine. This study introduces a novel technique for vertex augmentation, leveraging cross-link…

Level of Evidence V This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors …

[BACKGROUND] The nasal ala region significantly affects facial aesthetics and function. Botulinum toxin injections may enhance nasal appearance, but their precise impact on underlying muscles remains unexplored. Understanding the muscular a…

Glabellar filler injections are a popular non-surgical approach to address depressions and wrinkles caused by aging, muscle activity, and soft tissue loss. An anatomy-based technique emphasizes understanding the complex structure of the gla…

The inherent two-dimensional (2D) nature of ultrasonography (US) limits its accuracy in visualizing complex intraoral structures. This proof-of-concept feasibility study introduces a novel approach integrating motion-capture technology and …

Bunny lines are vertical and diagonal wrinkles attributed to contractions of the nasalis muscle. Common management involves botulinum toxin (BoNT) injections into wrinkles immediately below the nasal bridge. Here, we investigated the anatom…

[PURPOSE] The orbicularis oculi (OOc) and risorius muscles are typically regarded as distinct anatomic and functional units with no known direct muscular connections. Although rare variants of the facial musculature have been reported, thei…

[BACKGROUND] Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the d…

[BACKGROUND] Nonsurgical correction of a deviated nose using hyaluronic acid (HA) fillers offers a minimally invasive alternative to traditional rhinoplasty. This study presents a series of cases demonstrating the efficacy of HA fillers in …

Masseter are commonly botulinum neurotoxin targeted muscle for facial contouring in aesthetic field. However, paradoxical masseteric bulging is common adverse effect that has not been discussed with ultrasonographic observations. Retrospect…

[BACKGROUND] Hypertrophied submandibular glands provide a bulky contour to the lower face. Botulinum neurotoxin injection methods are commonly used for facial contouring; however, no studies have suggested injection points because of the la…

[INTRODUCTION] The advances of self-crossing hyaluronic acid (SC-HA) fillers combination use with polydioxanone thread in minipigs were examined for compatibility, effectiveness, and immune response. [MATERIALS AND METHODS] A 12-week exper…

[BACKGROUND] Botulinum toxin injections are widely sought after in the field of medical aesthetics, offering consumers a variety of brand choices. Two commonly available botulinum toxin products, onabotulinumtoxinA and neubotulinumtoxinA, a…

[PURPOSE] The anterior belly of the digastric muscle (ABDM) is the target of botulinum toxin injection; however, anatomical considerations related to the injection point are absent. This study used Sihler's staining to analyze the intramusc…

Botulinum toxin can be used for various purposes to enhance neck aesthetics, addressing concerns such as platysmal bands, optimizing the cervicomental angle, preventing worsening of horizontal neckline and decolletage lines during aging, su…

[OBJECTIVE] This study aims to evaluate the effects on bite force and muscle thickness of the botulinum toxin (BoNT) injection for patients with sleep bruxism (SB) by comparing injections into the masseter muscle only and both the masseter …

[INTRODUCTION] Tailoring surgical interventions to target age-related transformations is paramount. Many candidates seeking blepharoplasty commonly exhibit eyebrow ptosis, underscoring the necessity for surgeons to possess a comprehensive u…

[BACKGROUND] This review addresses the intricacies of non-surgical rhinoplasty, particularly focusing on the utilization of absorbable sutures known as "Volumizing threads" in combination with fillers. The aim is to explore the enhanced pre…

[BACKGROUND] The septal L-strut extension graft (SLEG) consists of anterior extended spreader graft and caudal septal extension graft. SLEG is used to increase the anterocaudal projection from a low-profile nose by creating the de-novo sept…

[BACKGROUND] An increasing number of reports on breast implant-associated anaplastic large-cell lymphoma have recently raised concerns about the potential influence of breast implants on carcinogenicity, particularly implants with a texture…

The black triangle resulting from interdental papilla (IDP) loss is associated with poor aesthetics and difficulty in pronunciation and food impaction. There is limited knowledge of gingival tissue inflammatory response to hyaluronic acid (…
