“…They reported that 41 patients (26%) developed recurrent metastasis out of 177 neck dissections in the neck and only four of them (3%) were in level V. In these four patients, level III or IV lymph nodes were shown histologically to have extracapsular spread at the time of the original dissection. None of the metastases at level V were from oral or oropharyngeal primary tumors 17. According to Davidson, obvious involvement of level IV must exist to dissect level V 10.…”
Because level V was not involved in any patient when the other levels were not involved, it might be reasonable to preserve level V especially in clinically and intraoperatively N0 patients.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
