Deep cervical and subclavian regions, anterolateral view, right side.The brachial plexus has been exposed and elevated. Fig. 7.15. Head and neck dissection, anterior view, right side.The right half of the maxilla, mandible, tongue, and oropharynx have been removed to show the prevertebral space, infratemporal fossa, and parapharyngeal space. The infrahyoid muscles and clavicle have been removed on both sides. A segment of the right common carotid artery and the internal jugular vein have been removed. Fig. 7.16. Enlarged view of the dissection in Fig. 7.15.Fig. 7.17. Deep dissection of the neck, anterior view, right side.A segment of the common carotid artery and the internal jugular vein have been removed to expose the vagus and phrenic nerves. Fig. 7.18. Deep dissection of the head and neck, anterolateral view, right side.The internal jugular vein and venous plexus have been removed. The pharynx and trachea have been retracted medially to expose the laryngeal nerves. The vagus nerve and the inferior thyroid artery have been retracted medially to expose the vertebral artery. Fig. 7.19. Deep dissection of the head and neck, anterolateral view, right side.The external carotid artery has been retracted anteriorly. The carotid sinus and body have been exposed. Fig. 7.20. Deep dissection of the head and neck, anterior view.The right half of the pharynx and larynx has been removed to expose the prevertebral plane. Fig. 7.21. Enlarged anterior view of the right infratemporal fossa and the parapharyngeal and prevertebral spaces.The external carotid artery has been retracted laterally to expose its branches. Fig. 7.22. Lower cervical and upper thoracic region, anterior view, right side.The ansa subclavia and recurrent laryngeal nerve have been exposed. Fig. 7.23.
