Ultrasound guidance refers to using diagnostic ultrasound imaging in real time to visualise facial anatomy, blood vessels, filler placement, and tissue layers during injectables and complication management. It significantly increases safety, accuracy, and treatment outcomes in modern aesthetic practice.

✅ 1. Why Ultrasound Guidance Is Important
A. Safety
• Identifies vascular structures to avoid intravascular injection
• Helps prevent complications such as vascular occlusion, skin necrosis, blindness
• Allows safe injection in high-risk regions (tear trough, nose, nasolabial fold, temples)
B. Precision
• Visualises exact tissue layer (dermis, subcutaneous, deep fat, SMAS, periosteum)
• Ensures filler or anti-wrinkle units are placed exactly where intended
• Reduces risk of overfilling or asymmetry
C. Filler Management
• Locates previously injected dermal filler (even years old)
• Enables targeted hyaluronidase injections to dissolve filler
• Helps diagnose nodules, granulomas, or migration
D. Complication Diagnosis
Ultrasound can help diagnose:
• Vascular occlusion
• Filler embolus
• Inflammatory nodules
• Abscess / infection
• Edema vs retained filler
• Vascular compression / impingement
