目的探讨MRI对评估各种感觉性神经性耳聋(SNHL)的价值。方法回顾性分析165例SNHL患者的MRI资料,部分与CT作了对比。结果165例中,MRI发现有57例异常(阳性率34.5%),共16种病变,其中儿童(<14岁)以先天性异常-前庭导水管扩大(5例)最常见,成人以听神经瘤(16例)为主,MRI对膜迷路纤维化、出血、微听神经瘤等病变的显示比CT具有明显优势。结论MRI对SNHL病因的诊断很有帮助,是可靠的影像学检查方法。
Objective To investigate the value of MRI in assessing various sensory neuropathy deafness (SNHL). Methods The MRI data of 165 patients with SNHL were retrospectively analyzed, and some of them were compared with CT. Results Among the 165 cases, 57 cases were found abnormal in MRI (34.5% positive rate), with 16 kinds of pathological changes. Of them, children (<14 years old) had congenital abnormalities - vestibular aqueduct enlargement (5 cases) (16 cases). MRI showed obvious advantages over CT in showing lesions such as fibrosis, hemorrhage, and micro-acoustic neuroma. Conclusion MRI is helpful for the diagnosis of SNHL and is a reliable imaging method.
