Abstract:
Objective: : To investigate whether development of the sph e noid sinus affect the surgical approach via saddle area. Methods: The pneumatization of sphenoid sinus of 50 cadaver heads was studied through t hinner CT scanning of coronal, sagittal and axial position. The sphenoid sinus w as classified according to the degree of pneumatization of sphenoid sinus toward s sphenoid bone, small wing of sphenoid bone and epippium. Results: There were 4% conchal, 18% pre-sellar, 18% semi-sellar, 14% sellar, 46% sellar -occipital in 100 sphenoid sinus cases. The transversal diameter of left and ri ght was 18.48 mm and 17.58 mm; The sagittal diameter of left and right was 2 2.20 mm and 20.82 mm, The vertical diameter of left and right was 21.02 mm and 2 0.38 mm. The distance between centre track and the later wall of sphenoid sinus was 14.78 mm in left side and 15.18 mm in right side. Conclusion: Thinner CT scanning with coronal and sagittal position can clearly show pneum atization of sphenoid sinus on both sides. Different pneumatization of sphenoid sinus provide anatomical basis for choosing operation approach.
