Figure 1

Cartoon representation of a sagittal section through the human nasal cavity showing the high-yield area of olfactory epithelium (OE). The peppered pattern demonstrates the area of the nasal septum most often associated with OE based on averaging from multiple autopsy specimens and shows the positional relationship among easily identifiable nasal structures. Notice that the OE typically does not reach the anterior edge of the middle turbinate in adults. F = frontal sinus, MT = middle turbinate, S = sphenoid sinus, asterisk = cribriform plate.
