@drtimpearce's cheek filler advice looks solid, actually

What did @drtimpearce actually say?

Dr. Tim Pearce demonstrated a tactile assessment technique for cheek filler placement, arguing that the zygoma's surface geometry should dictate both needle angle and entry point. His core claim: if you position an instrument flat against the upper surface of the zygoma and it stabilizes, you've found your reference plane. "If you push with an instrument with a flat end... if you're directly over the surface it's quite stable. It doesn't really want to move." From there, he says the bone's projection angle tells you which direction filler will push the overlying skin, which then informs where you enter with your needle or cannula.

This is a technique-oriented teaching video aimed at practitioners, not patients. The content is specific, anatomically grounded, and framed around a practical clinical decision: where to place filler on the lateral cheek to achieve a predictable result.

Does the science back this up?

Broadly, yes. The anatomical logic here is well-supported. The zygoma's upper surface does function as a reliable scaffold for lateral cheek augmentation, and the relationship between periosteal filler placement and soft tissue projection is documented in the literature.

Cotofana et al. (2018, Plastic and Reconstructive Surgery) produced detailed cadaveric mapping of facial fat compartments and their relationship to underlying bony landmarks, confirming that the zygoma's lateral prominence is a consistent reference point across anatomical variations. Raspaldo et al. (2015, Journal of Cosmetic and Laser Therapy) also described zygoma-referenced injection planes as a way to improve safety by reducing proximity to the zygomaticofacial and zygomaticotemporal neurovascular foramina when staying truly periosteal.

The tactile feedback concept, using instrument stability to confirm you're on the bone surface rather than angled off it, is not formally studied as an isolated variable, but it mirrors principles taught in cadaveric-based training programs and aligns with surface palpation methods described in facial anatomy texts by Rohrich and Pessa (2007, Plastic and Reconstructive Surgery).

What did they get wrong (or right)?

Pearce gets the anatomy right, and the tactile feedback method is a legitimate teaching tool. Credit where it's due: this is cleaner and more anatomy-specific than the vague "inject in the triangle" advice that floats around social media.

That said, there's a meaningful gap in the video. He frames this as if bone-guided placement is a safety mechanism, but staying on bone does not automatically protect against vascular injury. The zygomaticofacial foramen exits onto the lateral zygomatic surface, and its location varies. Pessa et al. (1999, Plastic and Reconstructive Surgery) documented significant variability in foramen position. A technique that relies on "feeling for the surface" without ultrasound or a detailed understanding of individual vascular anatomy carries real risk that this clip doesn't acknowledge.

He also says the bone projection "tells me which direction... the skin will push." That's a simplification. Soft tissue behavior depends on the volume injected, the depth plane, the viscoelastic properties of the specific product used, and the pre-existing ligamentous architecture. Bone geometry is one input, not a deterministic predictor of skin movement.

What should you actually know?

If you're a patient considering cheek filler: the zygoma-referenced approach Pearce describes is a legitimate anatomical framework used by trained injectors. It is not a beginner technique, and it is not risk-free. Vascular occlusion events in the midface, including cases affecting the infraorbital and zygomaticofacial vessels, have been reported in peer-reviewed literature (Beleznay et al., 2015, Dermatologic Surgery). Bone proximity does not equal vascular safety.

If you're a practitioner watching this: the tactile stabilization test for confirming periosteal depth is a useful clinical heuristic. But it should be one layer of a decision framework that includes knowing the patient's vascular anatomy, using aspiration or low-injection-pressure protocols, and having hyaluronidase immediately available if HA filler is used. Using bone as your sole guide without accounting for neurovascular exit points is incomplete practice.

The video is a teaser for a paid membership. The technique shown has clinical merit, but the risks of midface injection are compressed out of frame.
