Dissection of anterior and lateral regions of neck
Larynx; relation to oral cavity, oral and laryngeal parts of pharynx, left lateral view
The left wall of the pharynx has been resected in such a way that the soft palate and left pharyngopalatine arch (20) are preserved. The left glossopalatine arch (15) has been divided and the ends separated. The lateral (attached) surface of the left palatine tonsil (23) is exposed. The hyoid bone has been resected to the midline and the epiglottic cartilage exposed.
