SNHL in children is an important issue. Cochlear implant is a highly technological device that is surgically inserted in the cochlea to solve this issue. To evaluate types of anomalies of the inner ear in children with sensorineural hearing loss in a tertiary care hospital and confirm that the routine MRI, MR cisternography and HRCT provides the surgeon with the imaging finding and criteria of patients candidates for CI. Patients and method: 600 patients with SNHL underwent HRCT and MRI. CT examinations were normal in 457 patients (76.2%) and 143 patients (23.8%) with inner ear anomalies. MRI examinations were normal in 440 patients (73.3%) and had inner ear anomalies in 160 patients (26.7%). 3D bFFE and 3D DRIVE was summarized. The 3D bFFE sequence was statistically significantly better than the 3D DRIVE for the demonstration of the cochlear vestibule. Superior, inferior vestibular nerves and facial nerves while 3D DRIVE is superior to 3D bFFE in the visualization of the semicircular canals. HRCT and MRI provide accurate anatomical delineation of complex inner ear structures and 3D improves pre-implant evaluation.
儿童感音神经性听力损失是一个重要问题。人工耳蜗是一种高科技设备,通过手术植入耳蜗来解决这一问题。评估三级护理医院中感音神经性听力损失儿童的内耳异常类型,并确认常规MRI、磁共振脑池造影和高分辨率CT为外科医生提供人工耳蜗植入候选患者的影像学发现和标准。患者与方法:600例感音神经性听力损失患者接受了高分辨率CT和MRI检查。457例患者(76.2%)CT检查正常,143例患者(23.8%)存在内耳异常。440例患者(73.3%)MRI检查正常,160例患者(26.7%)存在内耳异常。总结了三维稳态自由快速成像(3D bFFE)和三维驱动平衡快速成像(3D DRIVE)。在显示耳蜗前庭、上、下前庭神经和面神经方面,3D bFFE序列在统计学上显著优于3D DRIVE,而在显示半规管方面,3D DRIVE优于3D bFFE。高分辨率CT和MRI提供了复杂内耳结构的准确解剖轮廓,三维成像改善了植入前评估。
