Dissection of nasal fossae, nasal pharynx, and palate
Nasal septum and left nasal fossa; branches of sphenopalatine ganglion, left superolateral view
The left orbit has been removed except for the remnant of the medial orbital margin (frontal process of maxilla) which has been preserved for purposes of orientation. The nasolacrimal duct (9) has been opened. The left maxillary sinus has been resected except for its floor (14). The mucosa of the lateral wall of the left nasal fossa (4) and the nasal conchae (13,19) have been partially removed to expose the nasal fossa. Part of the mucosa of the septum and floor of the nasal fossa has been removed. A window has been cut through the hard palate and the anterior palatine nerve and major palatine artery dissected. The left ethmoidal air cells have been removed and the left sphenoid sinus opened.
