OBJECTIVE: To find out the relation of the olfactory nerves, the optic nerve, and the nasal sinuses. Provide anatomic data for not to damnify olfactory nerves in the surgery.
METHOD: To measure the olfactory nerves, the olfactory bulb, and olfactory tract on 16 adult cadaveric specimens, and observe the relation of the olfactory nerves, the optic nerve,and the nasal sinuses.
RESULT: Length of the olfactory tract was (29.32 +/- 2.11) mm, width of the olfactory tract was (3.36 +/- 0.83) mm. The distance from the midpoint of the olfactory tract to the midline of the skull was (5.48 +/- 1.02) mm. The angle between olfactory tract and midline of the skull was (21.32 +/- 3.28) degrees. Length of the olfactory bulb was (10.43 +/- 2.35) mm, width of the olfactory bulb was (5.12 +/- 0.62) mm. 27/32 olfactory tracts were border upon with sphenoid sinus and ethmoid sinus, 3/32 olfactory tracts were border upon with ethmoid sinus, 2/32 olfactory tracts were border upon with frontal sinus. All olfactory tracts crossed the optic nerve at the internal meatus of optic nerve canal. The olfactory bulb and ethmoid bulb were on equal line.
CONCLUSION: Almost all olfactory tracts were lied in the inboard of the orbital cavity, protect the roof of the nasal sinus to avoid damnify the olfactory nerves. It is easy to pull out the olfactory nerves when raising the cerebra in the operation of anterior cranial fossae.
