Abstract
Doppler ultrasound can be used to detect almost all arteries of the face before injecting
the hyaluronic acid (HA) filler. The relatively more dangerous sites of filler injection
are the glabellar wrinkle, forehead, temple, nose, and nasolabial fold area, and it
is recommended to map the vasculature of these areas by Doppler ultrasound before
performing filler injection. The Doppler ultrasound detection method is included as
a video. Internal carotid arterial branches, the supratrochlear, supraorbital, and
dorsal nasal arteries, and external carotid arterial branches, the superficial temporal
and facial arteries, are very important arteries when injecting HA filler; thus, Doppler
ultrasound detection is recommended.
