Many surgical and nonsurgical options are available to patients seeking facial rejuvenation. In this review, we aim to provide an overview of the current trends in facelift and necklift procedures while simultaneously highlighting the utility of nonsurgical treatments. A comprehensive literature review was performed using the PubMed, Google Scholar, and Cochrane Library databases, with the objective of including recent literature published on facelift and necklift procedures from 2015 to 2025. Articles were selected based on relevance, with a specific focus on including a wide breadth of techniques. A considerable body of literature has been published to further classify the soft-tissue anatomy of the face and neck. In particular, these studies focus on the characterization of the three-dimensional anatomy of the facial nerve with emphasis on safe planes of dissection to avoid inadvertent facial nerve injury. The current literature continues to debate both the theoretical and practical advantages and disadvantages of various facelift techniques. Broadly speaking, facelift techniques can be divided into those that manipulate the superficial musculoaponeurotic system (SMAS) layer on its superficial surface and those that undermine the SMAS to varying extents. Numerous approaches are available to improve the contour of the neck and jawline, including manipulation of the platysma muscle and subplatysmal volume reduction. Other surgical procedures and nonsurgical treatments should be considered to optimize and enhance facelift and necklift results. Advancements in patient safety include a focus on minimizing complications while reducing the length of recovery. Facelift and necklift procedures remain the foundational pillars for facial rejuvenation. With attention to patient-specific anatomy, surgeons can work collaboratively with patients to provide global facial optimization by choosing appropriate facelift and necklift techniques in combination with other ancillary procedures. Doing so will deliver enduring, elegant results. Full article

Facial thread lifting has emerged as a minimally invasive alternative to traditional face-lifting procedures, with particular emphasis on U-shaped and I-shaped barbed threads. This review analyzes the anatomical considerations, procedural techniques, and clinical outcomes of different thread types for facial rejuvenation. The study examines the mechanical principles and lifting mechanisms of U-shaped “suspension type” threads versus I-shaped threads, highlighting their distinct characteristics and applications. The results indicate that U-shaped threads provide strong lifting effects, with success rates reported at 85–90% in achieving visible tissue elevation when anchored in the temporal area. However, these threads carry higher risks of complications, including bleeding (15–20%), dimpling (12–18%), and tissue damage at exit points (5–10%). In contrast, I-shaped threads demonstrate advantages in minimizing tissue trauma and patient discomfort, with complication rates below 5%, though they may provide less dramatic lifting effects. The study concludes that optimal outcomes are achieved through careful patient selection and customized combination approaches rather than reliance on a single thread type. Future directions point toward the development of hybrid techniques that combine the strengths of both thread types to maximize efficacy while minimizing complications. Full article

Objectives: Presently, data on the vascularization of the superficial musculoaponeurotic system of the face (SMAS) are lacking. Thus, the present study aimed to provide new conclusive data about the topography, density, and relationship of the SMAS blood vessels with other components, namely, the fibrous connective tissue and muscles. Methods: The study included a control lot of 42 cases from the archive of the radiology department. In this group, nuclear magnetic resonance angiography (MRA) was performed in order to identify the main sources of vascular supply. In the second group, tissue samples were collected from the midfacial region of 45 patients from the Oro-Maxillo-Facial and Plastic and Reconstructive Surgery clinics of ‘St. Spiridon’ County Clinical Emergency Hospital, Iasi. These patients received surgery for excision of tumoral formations that did not involve SMAS components. These samples underwent micro-CT analysis, hematoxylin and eosin (HE) staining, as well as immunohistochemical (IHC) staining for collagen type III, muscle tissue, and the vascular endothelium. Results: We discovered the particular way in which the SMAS components interrelate with vascularization and the regional differences between them. We have discovered a new vascular network specific to the SMAS, highlighted by both the micro-CT technique and microscopy on slides with special IHC staining. Significant differences were observed in the topographic arrangement, density, and relationships of the microscopic vasculature across midfacial regions. IHC staining provided morphological and functional information about the structure and vascularization of SMAS. Conclusions: The MRA technique could not detect the structural blood vessels of the SMAS and other methods for their in vivo visualization must be sought. The blood vessels of the SMAS mainly follow the topography of the muscle fibers. From the SMAS layer where they are found, the distribution branches reach the stroma of the region and the hypoderm. Our data can contribute to the development of surgical techniques tailored to each individual patient, as well as the enhancement of methods for stimulating cutaneous angiogenesis, improving scarring in this region, and advancing biotissue engineering techniques.

Background: The superficial musculoaponeurotic system (SMAS) is crucial for the structural integrity and dynamics of facial expressions and is a particularly important consideration during facelift surgeries. This study investigated the anatomical structure and continuity of the SMAS at the site where the zygomaticus major (Zmj) originates, which is where the SMAS extends from the lateral to the anterior aspects of the face. Knowledge of these aspects is crucial for understanding the mechanics of facial movements and also the aging process. Methods: Dissections of 66 specimens and histological analyses were used to explore the intricate relationships and attachments between the SMAS and facial muscles. Results: The findings indicated that at the Zmj origin site, the SMAS—connected to the inferior margin of the orbicularis oculi—covered the superficial surface of the Zmj fibers. As it tracked downward, the SMAS was observed to split into two layers lateral to the Zmj fibers, enveloping them both superficially and deeply. Additionally, as the SMAS continued forward, it ceased to be distinctly visible in the buccal area. Conclusions: These results provide a deeper understanding of the complex layering and interconnectivity of the SMAS, which supports facial dynamics and structural integrity. This information could be particularly useful in surgical and aesthetic procedures in the midfacial area. Full article

The study “Spaces of the Face for Filler Procedures: Identification of subSMAS Spaces Based on Anatomical Study” explores the anatomy of facial spaces crucial for safe and effective filler injections. By delineating the subSMAS (sub-superficial musculoaponeurotic system) spaces, this research highlights how these virtual compartments, bordered by fat, muscles, fascia, and ligaments, facilitate independent muscle movement and reduce the risk of damaging critical structures. The thicker and more robust skin of East Asians necessitates deeper filler injections, emphasizing the significance of accurately identifying these spaces. A cadaver study with dyed gelatin validated the existence and characteristics of these subSMAS spaces, confirming their safety for filler procedures. Key spaces, such as the subgalea-frontalis, interfascial and temporalis, and prezygomatic spaces, were examined, illustrating safe zones for injections. The findings underscore the importance of anatomical knowledge for enhancing facial aesthetics while minimizing complications. This study serves as a guide for clinicians to perform precise and safe filler injections, providing a foundation for further research on the dynamic interactions of these spaces and long-term outcomes.

The soft superficial tissues of the face are against gravity through an intricate network of ligaments and ligamentous attachments. The aim of this investigation is to delineate the relationship between the muscular, fibrous, and vascular components of the superficial musculoaponeurotic system of the face (SMAS) at the level of its periosteal fixation areas from advanced radiological and novel biomarkers’ perspectives. These areas represent key points underlying skin aging and the longevity of restorative surgery results. Methods: This study was carried out on 37 surgical specimens, excised from patients admitted for surgery. On the excised specimens, we used special immunohistochemical techniques, such as markers for collagen type III, angiogenesis, vascular endothelium (I-CAM2) and muscle fibers (MYH2). We performed a micro-CT evaluation of these 37 specimens. Results: The results of this study showed different radiologic and IHC characteristics of the means of periosteal fixation of the SMAS. Evidence of morphohistological and radiological peculiarities of the retaining ligaments highlights new data for future functional studies of these structures. Our research must be continued with larger groups of subjects and through detailed methodological studies of vascular microperfusion and could represent an important new step in biotissue engineering and the customization of surgical techniques involving the sub-SMAS layers.

Reconstruction of the temporomandibular joint (TMJ) region is challenging. The conventional direct preauricular incision permits only limited access to the TMJ and surrounding structures, therefore risking injury to the facial nerve during retraction. The ideal approach allows sufficient exposure, preservation of underlying neurovascular structures, and achieves an optimal aesthetic outcome. We describe a preauricular posttragal incision with a superficial musculoaponeurotic system flap to allow wide exposure of the zygomatic arch, TMJ, condyle, and coronoid process. We postulate that this approach improves access, lessens the amount of retraction required, and creates a more inconspicuous scar. Full article
