Abstract:
In the microsurgical dissection of the lateral wall of the cavernous sinus, interrelationships of its nerves have been studied in 100 Korean adult half heads. And in the serial coronal section of the cavernous sinus in 10 half heads, the structures of the lateral wall have been studied. The relationships of the nerves of the lateral wall were classified to five types according to the course of the trochlear nerve. Each length of the Parkinson's triangle and the angle between trochlear and ophthalmic nerves were measured. There data were compared with those of the other races. The lateral wall of the sinus was composed of two layers. The orientation of the fibers of the deep layer was variable in regions. The oculomotor nerve was enveloped with sheath extended from dura mater and it was connected with deep layer of the lateral wall. The trochlear nerve was enveloped with sheath formed y division of innermost part of the deep layer. The venous sinus was found between the two layers of the lateral wall. The neurosurgical significance of the lateral wall of the sinus was discussed.
