This dissertation examines the evolution, principles, and clinical relevance of selective and radical neck dissection in managing cervical metastasis of head and neck cancers. It highlights how radical neck dissection, once the standard, ensures comprehensive removal of lymphatic tissue but is associated with significant morbidity. In contrast, selective neck dissection aims to preserve non-lymphatic structures while targeting only the nodal groups at highest risk, thereby reducing functional deficits without compromising oncologic safety. The study analyzes indications, anatomical considerations, surgical techniques, and outcome predictors for each approach. Emphasis is placed on evidence-based decision-making, balancing oncologic control with quality of life. Ultimately, the dissertation underscores the importance of individualized treatment planning to achieve optimal patient outcomes in contemporary head and neck oncology.
