composite resection
En bloc surgical removal of primary tumor involving multiple anatomic structures or tissue planes. Often includes combined soft tissue and bony resection in advanced head and neck cancers.
Full Definition
Composite resection refers to the en bloc surgical removal of malignant tumors that involve multiple anatomic structures, requiring resection of both soft tissue and bony components in a single specimen. This approach is commonly employed in advanced head and neck cancers where the tumor crosses tissue planes or invades adjacent structures such as mandible, maxilla, or skull base. The technique ensures complete tumor removal while maintaining specimen integrity for accurate pathologic assessment of margins and extent of invasion. Composite resections often require immediate reconstruction with free tissue transfer to restore form and function.
Usage
Usage note: Emphasize en bloc nature; distinguish from staged or piecemeal approaches.
