supraperiosteal dissection
Surgical technique of separating tissues in the plane just above the bone's outer membrane.
Full Definition
A precise surgical dissection technique performed in the anatomical plane between the periosteum (bone's outer covering) and overlying soft tissues. This approach is commonly used in facial cosmetic surgery, particularly in facelifts and brow lifts, where maintaining this specific plane helps preserve important anatomical structures while allowing for effective tissue mobilization. Supraperiosteal dissection provides excellent visualization of bony landmarks and minimizes trauma to surrounding tissues. This technique is distinguished from deeper subperiosteal dissection, which involves elevation of the periosteum itself.
Usage
Usage note: Critical to distinguish from 'subperiosteal' which involves a deeper plane of dissection.
