Supraperiosteal Plane
Pronunciation: soo-pra-peh-ree-OS-tee-al playn
The tissue layer immediately above the periosteum (the membrane covering bone), a common target plane for deep structural filler injections.
Full Definition
The supraperiosteal plane describes the anatomical tissue space situated directly superior to the periosteum—the fibrous membrane enveloping bone. In aesthetic injectable practice, this plane is targeted when placing deep filler boluses for structural augmentation of areas such as the chin, malar eminence, and pyriform aperture. Editors working on injection technique papers must verify that the plane is accurately identified and consistent throughout a document, as confusion with the sub-SMAS or subdermis planes can have significant clinical implications. The adjective 'supraperiosteal' is sometimes rendered as 'supra-periosteal' (hyphenated); editors should apply house style consistently.
Usage
Usage note: Check house style for hyphenation: 'supraperiosteal' (closed) is more common in US journals; some UK publications use 'supra-periosteal'. Apply consistently.
