Human Nasal Cavity and Paranasal Sinuses Anatomy Diagram #48770 (License: Personal Use)

This classic anatomical illustration shows a coronal section through the human skull, highlighting the nasal cavity, superior meatus, middle meatus, inferior meatus, and the four paired paranasal sinuses-frontal, maxillary, ethmoid, and sphenoid. Key landmarks include the conchae (turbinates), nasal septum, and openings into the nasal passages, essential for understanding sinus drainage and airflow. The diagram is rendered in precise line art typical of early 20th-century medical textbooks.

Used in medical education, otolaryngology resources, anatomy textbooks, and patient education materials to explain sinus anatomy, infections, or surgical approaches; matches user intent for learning or referencing craniofacial anatomy.
