Bolus Technique
Pronunciation: BOH-lus tek-NEEK
An injection method in which a single, discrete depot of filler is deposited at one anatomical point before the needle is withdrawn.
Full Definition
The bolus technique describes the delivery of a concentrated volume of dermal filler at a single point, creating a small rounded depot within the tissue. It contrasts with linear threading and fanning techniques, which distribute product along a tract. Editors encounter the term in procedure descriptions, technique comparison studies, and product training materials. Correct usage requires specifying the tissue plane (e.g., deep fat compartment, supraperiosteal) when the bolus is placed, as plane omission can render the description clinically ambiguous. The word is sometimes misspelled 'bolous'.
Usage
Usage note: Always specify the anatomical plane alongside this term in procedural copy to avoid ambiguity.
