Dissection of head and neck from a posterior approach
Relation of pharynx to cervical spine
The left half of the cervical spine, together with the prevertebral muscles and fascia, has been resected and the muscles of the posterior wall of the pharynx brought to view by removal of the buccopharyngeal fascia. The left carotid sheath has been cut away.
