Abstract

The lymph nodes most frequently involved with metastasis in patients with squamous cell carcinomas of the oral cavity are those in level II and III. In addition, the nodes in level I are frequently involved in patients with carcinoma of the lips, floor of the mouth, anterior oral tongue and buccal mucosa. This chapter covers discussion on selective neck dissection (SND) I–III/IV. The patient is positioned on the operating table with the neck extended, if necessary, with a roll under the shoulders, the head turned towards the opposite side and stabilized with a foam doughnut. Dissection of the submandibular and submental triangles, superior lateral dissection: level IIA, dissection of level IIb, and dissection of Level III are the topics which are discussed briefly in this chapter with the help of well-illustrated figures.
