It seems like it's radonc dogma to cover the entire post-op bed in head and neck cases. Wondering how you all feel about this? Our local ENT-onc's neck dissection scars almost always extend over almost the entire length of the parotid. Have a young patient now (<40) with a well-lateralized T4N0 mandible CA s/p composite resection and bilateral neck dissection. 40 something nodes negative, no LVSI, but close margins at the primary. If I cover the entire post-op bed and scar, I'm knocking out both parotids. Was a contralateral neck dissection even necessary and do I really have to go back and chase the node negative neck because of possible contamination?!
