Abstract

This chapter discusses neck dissection, where deep cervical fascia of the neck is divided into three layers: superficial, middle and deep. The middle layer of the deep cervical fascia, also called the visceral fascia, surrounds the visceral structures of the anterior portion of the neck which include the pharynx, larynx, trachea, esophagus and thyroid. The carotid sheath encircling the jugular vein, common carotid artery, and vagus nerve is formed by all three layers of the deep cervical fascia. Metastases from cancers of the larynx can occur to the paratracheal lymph nodes. CT and MRI are valuable for assessment of resectability of large metastatic deposits in the neck, because in most instances they can define the relationship of a metastatic tumor with critical adjacent structures, such as the common and internal carotid artery, cervical spine, vertebral artery and brachial plexus.
