plane of dissection
The anatomical layer or tissue interface along which surgical separation is performed during oncologic resection.
Full Definition
The plane of dissection refers to the specific anatomical layer or tissue interface that surgeons follow when separating tissues during cancer surgery. Proper selection of the dissection plane is crucial for achieving clear margins while preserving vital structures and minimizing morbidity. In oncologic surgery, the plane must be chosen to ensure adequate clearance around the tumor, often requiring dissection through healthy tissue rather than along natural tissue planes that might be compromised by tumor invasion. The choice of plane affects both the completeness of resection and the functional outcomes for the patient.
Usage
Usage note: Often used with anatomical descriptors (e.g., 'suprafascial plane of dissection').
