Abstract

IP type 2, 8 IP type 3) and 54 controls. The CNCW and IACW were measured in axial temporal computed tomography sections. The CNA and facial nerve area (FNA) were measured in the distal IAC on the sagittal-oblique plane of 3D constructive interference steady-state T2-weighted magnetic resonance images. Results: CNA and CNA/FNA values for each IP type differed significantly compared with the control group. However, the CNCW and IACW values did not differ significantly. The CNA was the least in IP 1 cases. Five CN aplasia were detected, and all were associated with IP type 1 anomaly (3.5% of all, 5.6% of IP types, and 19.2% of IP type 1 cases). CN hypoplasia was observed in 10 IP type 1 (38.5% of IP 1), 6 IP type 2 (6.8% of IP type 2), and 1 IP type 3 (12.5% of IP type 3) ears. None of the CN hypoplasia had a CNC hypoplasia. Conclusion: CN aplasia and hypoplasia most frequently accompanied with IP type 1 in our study. Therefore, they need an extra interest in CN evaluation. CNCW and IACW are not very useful in predicting CN dysplasia in IP cases.

不完全分区型耳蜗神经与耳蜗神经管尺寸的关系

IP类型2、8个IP类型3）和54个控制。CNCW和IACW是在轴向时间计算机断层扫描切片中测量的。在三维构造干涉稳态T2加权磁共振图像的矢状斜面上测量远端IAC的CNA和面神经面积（FNA）。结果：与对照组相比，每种IP类型的CNA和CNA/FNA值均有显著差异。然而，CNCW和IACW值没有显著差异。在IP 1病例中CNA最少。检测到5例CN发育不全，均与IP 1型异常有关（占所有病例的3.5%，IP类型的5.6%，IP 1型的19.2%）。在10只IP 1型（IP 1的38.5%）、6只IP 2型（IP 2的6.8%）和1只IP 3型（IP 3的12.5%）耳朵中观察到CN发育不全。CN发育不全均无CNC发育不全。结论：CN发育不全和发育不全最常伴有1型IP。因此，他们需要对CN评估有额外的兴趣。CNCW和IACW在IP病例中预测CN发育不良不是很有用。
