The “Randomization Volume” corresponds to the pN0 hemi-neck(s). The neck volumes included in the “Randomization Volume” depend on whether the patient had an ipsilateral vs. bilateral neck dissection, and the pathological findings in each hemi-neck(s). Patients with bilaterally involved neck nodes are ineligible. Patients with an ipsilateral neck dissection with positive lymph nodes are ineligible unless they undergo a contralateral neck dissection that is pN0. If randomized to standard treatment volumes (Arm 1), all contoured volumes, including the “Randomization Volume” will be treated. If randomized to omission of the pN0 neck (Arm 2), the “Randomization Volume” will be omitted from treatment planning
