Prognostic value of lymph node count from selective neck dissection in oral squamous cell carcinoma

Unlike the levels of anatomical exploration, there is no consensus on the extent of lymph node dissection, or lymph node count (LNC), during selective neck dissection (SND). The aim of this study was to validate the prognostic impact of LNC on survival and to determine an optimal LNC cut-off value for SND. A retrospective investigation identified 78 patients with a diagnosis of oral squamous cell carcinoma (OSCC) who underwent SND (levels I–III or levels I–IV). LNC and clinicopathological variables were analyzed for any association with survival in Cox proportional hazards models.
