In recent years, the medical aesthetics industry has shifted from extensive and experience-based operations to a refined, visualized and personalized diagnosis and treatment model. Traditional aesthetics medical treatment relies heavily on physicians' visual observation, manual palpation and clinical experience to judge subcutaneous anatomical layers.This model has many inherent limitations: large errors in dermal thickness assessment, low recognition of subcutaneous blood vessels and fascial layers, inability to identify the properties of previously injected fillers, and difficulty in precisely controlling the depth of photoelectric/injection energy therapies.The above problems can easily induce complications such as vascular embolism, facial uneven deformity, nerve damage and unsatisfactory treatment outcomes. In addition the lack of standardized quantitative methods to compare pre-operative and post-operative treatment outcomes has become a core difficulty hindering the safe and standardized implementation of medical aesthetic diagnosis and treatment.
High-frequency medical ultrasound boasts core advantages including non-invasive real-time imaging, zero ionizing radiation, convenient bedside operation, and high resolution for soft tissue imaging. It can clearly delineate delicate soft tissue anatomical structures such as the epidermis, dermis, subcutaneous fat, SMAS fascia, superficial blood vessels and tiny facial nerve branches, filling the subcutaneous blind zones invisible to the naked eye and undetectable by manual palpation — yet the lack of its standardized clinical application has become a core obstacle restricting the safe and standardized delivery of aesthetic medical treatment.
Common Periorbital issues: Upper eyelid wrinkle reduction, crow's feet elimination, under-eye bag contour correction, eyelid reshaping, etc.
Medical Aesthetics Precautions: The medial canthus and the medial vascular plexus of the upper eyelid are high-risk areas for injectable treatments
Projects Suitable for Palm Ultrasound:
u Upper Eyelid Wrinkle Reduction: Under ultrasound guidance, avoid the hazardous vascular plexus at the medial canthus and medial upper eyelid. Administer micro-doses of botulinum toxin to reduce upper eyelid wrinkles, combined with periorbital collagen filler to further improve static fine lines on the upper eyelid.
u Dynamic Crow's Feet Elimination: Under ultrasound guidance, inject botulinum toxin to erase dynamic crow's feet at the outer canthus.
Nasal area (nasal bridge, nasal tip, alae nasi, nasal base)
Common Nasal Issues: Low nasal bridge and flat radix; enlarged and rounded nasal tip, wide alae; sunken nasal base (the root of nasolabial folds)
Medical Aesthetics Precautions: Identify and avoid blood vessels including the dorsal nasal artery, lateral nasal artery, communicating branches of the angular artery, and branches of the facial artery
Ultrasound-Guided Applicable Procedures:
Low nasal bridge and flat radix
u Minimally invasive medium-long term: Visualize tissues via ultrasound, map injection areas, and perform ultrasound-guided hyaluronic acid injection for precise rhinoplasty;
Long-term solution: Visualize tissues via ultrasound, map implantation areas, and implant silicone, expanded polytetrafluoroethylene (ePTFE) prostheses or costal cartilage to achieve rhinoplasty outcomes. Postoperative ultrasound evaluation of implantation effects and monitoring of postoperative recovery.
u Enlarged and rounded nasal tip, wide alae
Visualize tissues via ultrasound, map surgical scopes, and select surgical methods: nasal tip reduction, alar reduction or nasal tip elevation and shaping.
u Sunken nasal base (the root of nasolabial folds)
Visualize tissues via ultrasound, evade vascular plexuses such as communicating branches of the angular artery, select filling areas and needle entry points, and choose fillers (hyaluronic acid, autologous fat, nasal prostheses) to improve nasal contour.
Midface malar region (above the zygomatic bone)
Common issues in the midface malar region: descended malar fat pads, hollowness and atrophy, deepened nasolabial folds, soft tissue laxity
Medical aesthetics precautions: Blood vessels here communicate with those around the eyes and nasal dorsum, making this the second most frequent site for retrograde facial embolism. In addition, avoid injuring the zygomatic facial nerve
Applicable projects for ultrasound-guided aesthetic treatment:
u Malar region contouring: Use ultrasound to visualize tissue layers and map out the malar filling area. Under real-time ultrasound guidance, perform hyaluronic acid or autologous fat injection to achieve a plump contouring result.
