Osteology
Lateral wall of left nasal fossa dissected
The left middle and superior conchae have been cut away and ethmoidal air cells widely opened. A window has been cut through the inferior concha to reveal the position of the nasal opening of the nasolacrimal canal (24). The specimen is viewed from the right side.
