Anatomical proposal for hyaluronic acid filler injection in subzygomatic arch depression: A dual‐plane injection technique

Abstract

A subzygomatic arch depression creates a bulky face outline. To smoothen these depressions and correct facial contours, hyaluronic acid filler injection methods are frequently used. However, the complexity of the subzygomatic region make it difficult for practitioners to effectively volume the region. The conventional injection of single layer injection has limitations of lack in volume addition and unwanted undulations and spreading. The anatomical factors were reviewed with ultrasonography, three‐dimensional photogrammetric analysis, and cadaver dissection. In this anatomical study, the present knowledge on localizing filler injection with a more precisely demarcated dual‐plane injection was suggested. This study presents novel anatomical findings related to the injection of hyaluronic acid filler injection in the subzygomatic arch depression.

Retrospective Study of Horizontal Neckline Correction Using Absorbable Braided Polydioxanone Threads

“…Age-related transformations in the neck can involve various alterations, including the accumulation of submental fat, skin looseness causing the loss of the cervicomental angle, bone loss, and compromised neck contours resulting from jowl formation [16][17][18][19][20][21]. Various substances such as botulinum neurotoxin, dermal fillers, and skin boosters are employed in the realm of aesthetics to eliminate wrinkles [9,10,[22][23][24][25][26][27][28][29][30][31]. Aesthetic treatment of horizontal neck lines is one of the most common requests from patients looking to improve their neck's appearance.…”

Why Do Nasolabial Folds Appear? Exploring the Anatomical Perspectives and the Role of Thread-Based Interventions

“…If the insertion plane of the cannula around the protruding malar eminence fails to maintain a consistent depth due to bending, it may result in a shallow procedural plane. Conversely, attempting to prevent a decrease in the depth of cannula advancement by passing too deeply through the area where the face folds toward the nasolabial fold could inadvertently intersect with the origin areas of the zygomatic muscles near the malar eminence [27,28]. This interference might impede the lifting motion towards the mouth corners and, in individuals with developed malar eminence, could potentially accentuate the prominence of this region by collecting tissues toward the malar eminence [20,21,28].…”

SMAS repositioning technique utilizing cog thread: Anatomical perspectives

“…14 When discussing the explanation of dual-plane filler procedures, the author often highlights that, except for the inner aspects of the face, where vertically oriented fibrous septa firmly attach the subcutaneous fat and skin to the underlying SMAS (superficial musculoaponeurotic system) to protect the facial structure and enable facial expressions through the movement of facial muscles, there is not ample space for filler injection. 15 This leads to the question of how such a space, suitable for performing thread lifting procedures with ease, is created during these procedures.…”
