ABSTRACT
Objective: To observe the gadolinium imaging findings of inner ear in patients with sudden deafness and to analyze its clinical features. Methods: From November 2017 to July 2020, 21 patients with sudden deafness in the People's Hospital of Dongsheng District, Ordos City were selected as the research objects, including 14 males and 7 females, aged 36-76 years, with a median age of 50 years. The course of disease was 1-19 days, with an average of 5.5 days. The patients received audiology tests, laboratory examination, and intravenous gadolinium angiography, each of whom was scanned twice by 3D-FLAIR sequence: once before intravenous gadolinium injection, and once again 4.5-6.0 h after intravenous gadolinium injection. The following corresponding clinical treatment was given. The imaging manifestations and clinical features were observed. Results: Among 21 cases of sudden deafness in acute stage, the signal intensity of 11 cases was significantly higher than that of the contralateral ear, and 2 cases had vestibular labyrinthine hydrops. In laboratory examination, only 2 cases of total deafness had increased WBC count and faster erythrocyte sedimentation rate, and the rest had no abnormality. The hearing types of 21 patients with sudden deafness were: total deafness in 8 cases, flat decline in 10 cases, low frequency decline in 1 case, high frequency decline in 2 cases. The total effective rate was 57% (12/21). The hearing types of 11 patients with abnormal gadolinium angiography were total deafness in 5 cases, flat decline in 5 cases and high frequency decline in 1 case. The total effective rate was 64% (7/11). Conclusion: Gadolinium angiography is abnormal in some patients with sudden deafness, and the permeability of blood labyrinth barrier may be increased, which is worthy of further study.
