Head & Neck Cancer — Unknown Primary, TNM Staging, Neck Dissection, and Salivary Tumors

This episode provides a comprehensive, high-yield review of head and neck oncology, focusing on squamous cell carcinoma, HPV-driven disease, staging systems, and surgical management.We begin with the classic presentation of a neck mass and unknown primary, then explore the evolving epidemiology of head and neck cancer, including the role of tobacco, alcohol, and HPV (P16-positive disease).Key concepts include the TNM staging system (with emphasis on tumor size, depth of invasion, nodal disease, and extranodal extension), as well as the levels of the neck and their relevance to lymphatic spread and surgical planning.We review operative strategies ranging from radical and modified neck dissections to selective approaches, along with site-specific management of oral cavity, oropharyngeal, and nasopharyngeal cancers, including principles of organ preservation and transoral robotic surgery (TORS).The episode also covers salivary gland tumors, including the 100:10:1 rule, the inverse rule of malignancy, and high-yield entities such as pleomorphic adenoma, Warthin tumor, mucoepidermoid carcinoma, and adenoid cystic carcinoma, with emphasis on surgical pitfalls and tumor biology.Part of Dr. Lara’s Plastic Surgery Compendium — a high-yield audio reference for plastic surgery trainees and surgeons.
