Abstract:Objective To determine the location of the supraorbital foramen(SOF) and infraorbital foramen(IOF) relative to paropia and the medial corner of the eye,and  provide more accurate data for dental and facial surgery.Methods Twenty embalmed adult cadavers (40 sides;16 men,4 women) were dissected to expose the SOFs and IOFs.The location of the SOFs and IOFs was evaluated with direct and photographic measurement.The data gained was analyzed by statistical method.Results The horizontal distances between the IOFs/SOFs and the medial corner of the eye to the distance between the medial corner of the eye and paropia ratios were measured,and their 95% confidence intervals were（0.22，0.31） and （0.34，0.49）.Their linear regression equations were EF=0.58CF+25.02（unit：mm） and  EF=0.51DG+24.20（unit：mm）,respectively.The vertical distances between IOFs/SOFs and the medial/lateral corner of the eye were (25.09±3.36)mm,(23.91±3.31)mm,(25.75±3.34)mm and (26.93±3.88)mm.The horizontal angles between IOFs/SOFs and the medial/lateral corner of the eye were 72.54°±7.13°,66.77°±5.17°,47.45°±6.57°, and 54.69°±8.38°. The vertical angle between the SOFs and the vertical line of pupil was 12.78°±6.82°.Conclusion The horizontal distances between the IOFs/SOFs and the medial corner of the eye and the distance between the medial corner of the eye and paropia have linear correlation;according to the result,the  different data in different subjects  can be calculated.
