Abstract

Abstract:

Objective　To observe the variations, and the relations between the cranial nerves travelling through the cavernous sinus by measuring the regions of the selected triangles of the cavernous sinus in order to provide anatomic data for microsurgical operation in cavernous sinus.　Methods　12 cases of adult cadaver heads were used to dissect, observe and measure the sizes of 8 selected triangles under the microscope.　Results　The selected cavernous sinus triangles included the Dolenc triangle, the oculomotor triangle, the supratrochlear triangle, the Parkinson triangle, the Mullen triangle, the anteriolateral triangle, the Kawase triangle and the Glasscock triangle. The sizes of the triangles were 77.75 mm2, 82.73 mm2, 45.00 mm2, 83.40 mm2, 66.38 mm2, 51.28 mm2, 121.65 mm2, and 161.67 mm2.　Conclusion　The area of the cavernous sinus triangle is the only route area of the neurosurgery cranial base surgery, and it is the operation range that can be referred in the surgery. Due to the variation of partial nerve and bone structure, it can lead to the reduction of partial triangular area and affect the operation. The measurement data of each triangle area can be used as a reference for the selection of surgical approach in clinical practice, and provide data support in the practice of virtual reality technology.

Key words: Cavernous sinus;　Anatomic triangle;　Variation; , Proportion；　Microsurgery operation
