Selective neck dissection of level IIB in cN0 laryngeal cancer: a systematic review and meta-analysis.

Purpose: The primary endpoint of the study was to quantitatively evaluate the presence of IIB neck level metastases in patients with laryngeal carcinoma, to provide valuable evidence to aid surgeons in the decision-making process for neck dissections. As a secondary aim this study analyzed the presence of factors that may be associated with a higher prevalence of metastasis.

Methods: Two independent authors (EE, MVV) searched for articles on PubMed, Cochrane, Embase, and Scopus databases.
