Anatomical study of anterior ethmoidal canal based on 0.1 mm ultra-high resolution CT
摘要
Abstract
OBJECTIVE To study the anatomic characteristics of the anterior ethmoidal canal(AEC)based on 0.1 mm ultra-high resolution CT.METHODS Nine cadavers(18 side orbits)fixed in 10%buffered formalin were enrolled and underwent U-HRCT and MSCT.Divided AEC into horizontal,superior oblique,and inferior oblique segments and observed the displaying rate of each section.Subjective evaluation of display situation was performed by two experienced radiologists independently.The diameter of each AEC segment was measured.RESULTS No significant difference was found in the display rate of the horizontal and superior oblique segments between U-HRCT and MSCT groups(P>0.05),the display rate of inferior oblique segment of U-HRCT group was significantly higher than MSCT group(P<0.05).There was no significant difference in the objective evaluation results between two evaluators and consistency was strong.Subjective scores of each segment of AEC in U-HRCT group were 10.00 points(9.75 points,10.00 points),2.00 points(2.00 points,3.00 points)and 8.00 points(6.00 points,10.00 points),in MSCT group were7.00 points(5.75 points,8.00 points),2.00 points(2.00 points,2.00 points)and 2.00 points(2.00 points,4.00 points).Subjective scores of horizontal and inferior oblique segments of AEC in U-HRCT were higher than MSCT(P<0.05).The anteroposterior diameter of the horizontal section of AEC is(0.92±0.12)mm,the axial diameter is(1.04±0.22)mm.The anteroposterior diameter of the inferior oblique segment is(0.47±0.08)mm,and the transverse diameter is(0.50±0.06)mm.The anteroposterior diameter of the superior oblique segments is(0.66±0.11)mm,and the transverse diameter is(0.72±0.20)mm.CONCLUSION U-HRCT is better to evaluate AEC than MSCT.It could be used to help to study the anatomic characteristics of AEC before surgery to avoid complications.关键词
