The record

Area
Mandibular angle · masseter
Technique
Ultrasound-guided intramuscular fat grafting
Access
Incision below the earlobe, 1.5 mm cannula
Study
20 patients · 3 countries · 2021-2022

What the study measured

20
patients: 10 men and 10 women
≈ 5.7 mL
of fat injected per side, on average
3
countries: Peru, Brazil and Mexico

How it was studied

The multicentre study included 20 patients with a mean age of 34. After harvesting, the fat was injected into the masseter on each side of the mandibular angle under ultrasound guidance.

Muscle thickness increased right after surgery, decreased at one month and remained significantly greater than before surgery, in men and women.

What the study does not allow us to claim

The thickness gained decreases during the first month; what the study measures is what remains above the starting point.

The authors state that long-term results still need evaluation.
