Dissection of nasal fossae, nasal pharynx, and palate
Right lateral wall of nasal fossa and nasal pharynx dissected; relations of palatine tonsil
Portions of the conchae have been cut away to expose the openings of the paranasal sinuses and nasolacrimal duct. The pterygopalatine canal (20) has been opened and the cartilage of the auditory tube exposed. The muscles of the palate have been dissected and the palatine tonsil removed. Structures which lie lateral and anterior to the tonsil have been dissected.
