Retrograde Injection
Pronunciation: RET-roh-grayd
An injection technique in which filler or other material is deposited along the needle or cannula tract as the device is withdrawn, distributing product evenly along a linear path.
Full Definition
In retrograde injection technique, the needle or cannula is advanced to the desired anatomical endpoint before any product is deposited; filler is then expressed as the instrument is slowly pulled back, creating a linear thread or column of material. This is contrasted with anterograde (or prograded) injection, where product is deposited as the device advances. Editors reviewing procedural descriptions in training manuals, peer-reviewed articles, or consent documentation must accurately distinguish these approaches, as the technique affects both the safety profile and the aesthetic outcome. 'Retrograde' is sometimes misspelled 'retrograde' with a transposed 'a' and 'e'; editors should verify spelling carefully.
Usage
Usage note: Clearly distinguish from anterograde injection in procedural descriptions. Confirm correct spelling: 'retrograde,' not 'retrograde.'
