I now make a point of pre-scanning the temple, the nose, and the piriform fossa and indeed, the center of the chin if I’m using a bio stimulator that is not easy to dissolve. But always, the nose, the piriform fossa, and the temple. So, I pre-scan. In some situations, I use it for ultrasound-guided injections of filler and unique circumstances where I see that it’s necessary. So, for example, in the nose when I’m treating the lateral aspect of the nose, when I am treating the whole nasal labial fold subcutaneously and when I’m treating the temple in the subcutaneous or interfacial plane.”
