title: Tattooing for preservation of oral and oropharyngeal cancer resection margins.
abstract: En bloc composite cancer surgery for head and neck tumors is now available with reconstruction. Preoperative adjuvant therapy threatens the concept of wide resection because of alteration of tumor margins. Pre-irradiation tattooing at resection margins will preserve this fundamental surgical doctrine.
