CHEEK MD CODES Injection Specifications
I cannot provide specific MD CODES injection parameters from the available evidence, as the provided studies focus on insulin administration, immunizations, and general facial filler safety rather than the detailed MD CODES protocol for cheek augmentation.
However, based on the limited relevant evidence available, here are the key anatomical considerations for cheek filler injections:
General Injection Depth Principles for Cheek Fillers
For mid-face rejuvenation using hyaluronic acid fillers, injection depth varies by anatomical location and treatment goal, with bolus injections performed at deeper planes for lifting and linear injections at more superficial planes for contouring. 1
Depth by Treatment Type
- Bolus injections for lifting: Performed at the most depressing points along the zygomatic arch and zygomatic eminence using 0.2-0.3 ml HA per site 1
- Linear injections for contouring: Performed in the deep fat pad of the medial cheek and infraorbital region using 0.4 ml HA 1
- Linear injections for volume replacement: Performed in the subcutaneous fat layer of lateral cheek using 0.8 ml HA 1
Critical Vascular Structures to Avoid
The facial artery poses the greatest vascular risk in the nasolabial fold region, running lateral to the fold with variable horizontal distances ranging from -1.90 mm to -6.92 mm depending on the vertical level. 2
Facial Artery Location Relative to Nasolabial Fold
- Upper 1/3 of nasolabial fold: Supraperiosteal layer injection is recommended to avoid the facial artery 2
- Lower 2/3 of nasolabial fold: Dermal layer injection along the fold is recommended 2
- The facial artery evolves into the angular artery in 83.7% of cases, maintaining a lateral position to the nasolabial fold 2
Safety Considerations
- Vascular complications arise primarily from arterial cannulation with filler material, which can lead to tissue loss, blindness, stroke, or death 3
- Practitioners must understand the facial arterial vascular supply systematically according to internal and external vascular territories 4
- Ultrasound imaging can be used to visualize anatomical layers, thicknesses, and dynamic changes during injection 1
Critical Limitation
The provided evidence does not contain specific MD CODES tabulated protocols with exact injection point numbers, precise depths in millimeters, or comprehensive vascular avoidance maps for the cheek region. To obtain this information, you would need to reference the original MD CODES training materials or publications specifically addressing this proprietary injection technique.
