R1: Include level Ia only in case of anterior tongue or anterior floor of mouth extension. R2: Include retropharyngeal nodes for posterior pharyngeal wall tumour extension. R3: include level VI in case of extension apex of prirform sinus or esophageal extension. R4: include level VI in case of trans- or subglottis extension.

R5: according to N-stage on each side of the neck. RP: retropharyngeal nodes.

NOTE: LEVELS ADJACENT TO POSITIVE LYMPH NODE AREAS SHOULD ALWAYS BE INCLUDED IN THE ELECTIVE CTV.
