Custom Midface Mask Implants in the Asian Face

Custom midface mask implants are a specialized form of facial augmentation designed to enhance the central midface (infraorbital rims, anterior maxilla, and cheek area as a continuous unit) rather than using separate cheek or tear trough implants. In Asian patients, their use has some distinct considerations due to typical skeletal and aesthetic differences.

What is a “midface mask” implant?

• A single, custom-designed implant (usually solid silicone or PEEK)
• Extends across:
  • Infraorbital rims (under-eye support)
  • Paranasal region (around the nose base)
  • Malar/cheek area
• Designed from 3D CT imaging for precise fit and symmetry

Why consider midface mask implants in Asian patients?

Common anatomical traits (generalized)

• Flatter midface projection
• Less anterior maxillary projection
• Wider bizygomatic width but less forward projection
• Tear trough hollowing due to skeletal support deficiency

Aesthetic goals often differ from Caucasian patients

• Avoid overly lateral cheek widening
• Emphasize forward (anterior) projection, not just lateral fullness
• Maintain natural ethnic identity while improving structure

Advantages of custom midface implants

• Holistic augmentation: Treats the entire midface as one unit ? smoother transitions
• Better tear trough support vs fillers or isolated implants
• Precise symmetry using patient-specific design
• Stronger structural change than fillers or fat grafting

Key design considerations in Asians

1. Controlled projection
   • Over-augmentation can look unnatural quickly
   • Subtle anterior projection is usually preferred

1. Avoid excessive lateral cheek width

1. • Many Asian patients already have adequate or wide bizygomatic distance

1. Infraorbital support is critical

1. • Helps with under-eye hollowing and “tired” appearance

1. Paranasal augmentation

1. • Often important to improve midface convexity and nasolabial angle

1. Soft tissue thickness

1. • Thicker soft tissues can blunt definition ? implant must compensate slightly

Materials commonly used

• Silicone (most common)
  • Easier to insert/remove
  • Smooth, well tolerated
  • Can be placed as a single unified implant
• PEEK
  • increasingly popular plastic material
  • due to rigidity often needs to be placed in multiple smaller segments

Surgical approach

• Typically intraoral (inside the mouth) to avoid visible scars
• Sometimes combined with:
  • Lower eyelid approach (for infraorbital precision)
• Fixation with small screws to the zygomatic buttress is commonly done.

Risks & limitations

• Infection (higher with intraoral approach vs external)
• Implant malposition (less common with custom implants)
• Nerve irritation (infraorbital nerve)
• Over- or under-correction
• Difficulty removing porous implants

Comparison to alternatives

When they are especially useful

• Flat midface with global deficiency
• Prominent tear troughs due to bone deficiency
• Revision cases where fillers/cheek implants failed
• Patients wanting permanent structural enhancement
