The document provides an overview of neck dissections, including their history, surgical anatomy of the neck, lymph node levels and staging, classifications of neck dissections, and indications for different types of neck dissections. It discusses the evolution of neck dissections from the radical neck dissection to more selective procedures. Key classifications covered are the radical, modified radical, and selective neck dissections, with the latter including supraomohyoid, lateral, and posterolateral variants. Indications and structures preserved for each type of dissection are outlined.
