Objective To study the feasibility of measuring diameters of the mid section of the vestibular aque‐duct back limb on 15°oblique sagittal image reconstructed using multi‐slice computed tomography (MSCT )images of temporal bone for detecting large vestibular aqueduct syndrome (LVAS) .Methods Temporal bone MSCT ima‐ges from 106 normal hearing individuals (212 ears)were used to reconstruct a standarized section image of the ves‐tibular aqueduct .The diameters of the mid section of the aqueduct back limb were measured to establish 99% con‐fidence intervals .Images from different age group ,male and female individuals and from the left and right sides were measure separately and the results were compared with those from 43 patients with LVAS .Results There was no significant differences of intermediate diameters between male and female ,the left and right ,and the differ‐ent age groups( t=0 .252 ,P>0 .05 ;t=1 .573 ,P>0 .05 ;F=0 .089 ,P>0 .05 ) .The mid value of the vestibular aqueduct back limb was 0 .76 ± 0 .15mm;99% confidence intervals:0 .41~1 .10 mm .The section size of this seg‐ment was greater in LVAS patients than in normal individuals ( t=7 .892 ,P<0 .05 ) .Conclusion The 15°oblique sagittal image was easily gained with the multiple projection reconstruction of MSCT .The 99% confidence inter‐vals:0 .41~1 .10 mm;The mid value of vestibular aqueduct back limb is greater than 1 .10 mm on suggests the di‐agnosis of LVAS .
