Abstract (EN): Objectives: The main objective of this study is to analyze factors associated with nodal yield in level II-IV selective neck dissections (NDs) and the secondary objective is to assess its impact on overall and disease-free survival. Methods: Observational retrospective study including adult patients submitted to level II-IV ND from January 2015 to December 2021 in the otorhinolaryngology department of a tertiary hospital center. Results: A total of 44 patients and 78 level II-IV NDs (34 bilateral and 10 unilateral) were included. The median age at diagnosis was 60 (22-74) years, and 93.2% of the patients were male. A lower nodal yield was significantly associated with previous radiotherapy (p = 0.042) and extranodal invasion (p < 0.001) and was non-significantly associated with older age (p = 0.065). Furthermore, on a Cox analysis adjusted to the cN status and age, the nodal yield was not associated with five-year disease-free survival (HR = 0.986; 95% CI = 0.922-1.054; p = 0.681) nor with five-year overall survival (HR = 1.006; 95% CI = 0.925-1.095; p = 0.888). Conclusion: A reduced nodal yield in level II-IV NDs was significantly associated with previous radiotherapy and extranodal extension and non-significantly associated with age. There was no association between the nodal yield and five-year overall survival or disease-free survival.
