Complete biodegradable nature of calcium hydroxylapatite after injection for malar enhancement: an MRI study

Figures & data

Figure 1 Injection scheme.

Notes: Crosses indicate insertion points. Arrows indicate direction of linear threads in fanning technique.
Abbreviation: VSDT, vertical supraperiosteal depot technique.

Figure 2 Illustration of the vertical supraperiosteal depot technique.

Notes: The clinician gathers up the skin with the non-injecting hand for maximum penetration and pierces the skin at the thinnest entry point using a 90° angle. At the level of the bone, the needle is repositioned and advanced slowly below the soft tissue before material deposition.

Figure 3 (A) Pre- and (B) immediate post-treatment photos after cheek augmentation and infraorbital hollow correction with 1.6 mL CaHA (cheek) and 0.2 mL hyaluronic acid (infraorbital hollow).

Abbreviation: CaHA, Calcium hydroxylapatite.

Figure 4 Horizontal sections from the cheek showing CaHA over a certain area corresponding the 3-dimensional cheek volumetry.

Notes: (A,B) MRI images acquired immediately after injection of CaHA for the cheek augmentation with a Siemens Magnetom Essenza 1.5 Tesla. Product shown over two MRI sections.
Abbreviations: MRI, magnetic resonance imaging; CaHA, Calcium hydroxylapatite.

Figure 5 Horizontal sections from the corresponding cheek area without CaHA.

Notes: (A,B) MRI images acquired approximately 2.5 years after CaHa injection with a Siemens Magnetom Skyra 3.0 Tesla. No CaHA was detectable in any of the corresponding MRI sections.
Abbreviations: MRI, magnetic resonance imaging; CaHA, Calcium hydroxylapatite.
