Objective: To explore the correlations of different appearances of labyrinthine 3D-FLAIR MRI with clinical features and prognosis in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). Methods: Clinical data of patients with unilateral ISSNHL hospitalized from May 2017 to January 2019 were retrospectively analyzed. According to the results of 3D-FLAIR MRI, the patients were divided into three groups including hyperintense with absorption, hyperintense without absorption and normal. The differences and correlations among the three groups in clinical characteristics (gender, age, deafness side, duration, treatment days, dizziness/vertigo, basic diseases, vestibular function, deafness classification and typing) and prognosis were analyzed by SPSS 20.0 software. Results: Data were collected from 1 245 cases, including 739 (59.36%) with normal signal, 288 (23.13%) hyperintense without absorption, and 218 (17.51%) hyperintense with absorption. The side ratio, treatment days, dizziness/vertigo incidence, vestibular dysfunction, deafness classification and typing were different among the three groups (P<0.001). The incidence of right side was significantly higher in both the hyperintense with and without absorption groups than that in the normal. The vestibular dysfunction was more common in the hyperintense with absorption group than in the normal and hyperintense without absorption groups. It showed statistical differences in the dizziness/vertigo incidence, deafness classification, treatment days, and deafness typing compared between groups, which was the most significant in the hyperintense with absorption group, followed by the hyperintense without absorption group. There was no statistical difference in the total effective rate among the three groups (P=0.139), whereas a significant difference in the recovery rate (P<0.001). The prognosis was significantly correlated with duration, age, treatment days and dizziness/vertigo in the normal group (all P<0.001), correlated with duration and treatment days in the hyperintense with absorption group (both P<0.001), only correlated with the duration in the hyperintense without absorption group (P<0.001). Conclusion: 3D-FLAIR MRI manifestation is closely related to the clinical features and efficacy of ISSNHL. It is helpful to clarify the pathology of inner ear, which is expected to be a new imaging indicator for disease evaluation.

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.

OBJECTIVE: To explore the characteristics of vertebral artery system in the patients with sudden deafness by using digital subtraction angiography (DSA). METHOD: Thirty-four cases of sudden deafness with vertebrobasilar artery ischemia confirmed by the color doppler ultrasound were undergone DSA in both side. The characteristics of vertebral artery, basal artery and before-cerebellum artery were analysis before specific therapy. RESULT: There is no related complication were occurred among 34 cases. Side vertebral artery was blocked in 2 cases, atherosclerosis was found in 5 cases. The right cerebellar artery anterior and the left cerebellar artery posterior were found filling defect or minor change in 29.4% (10/34) and 35.3% (12/34) of the patients, respectively. The right and the left arteria auditiva interna were found filling defect or minor change in 64.7% (22/34) and 73.5% (25/34) of the patients, respectively. After specific therapy, 8 cases were cured, the hearing of 9 cases were markedly improved, the hearing of 12 cases were improved efficient and 5 patients have no hearing improvement, the total effective rate was 85.3%. CONCLUSION The arteria auditiva interna and inferior anterior arteria cerebelli caused inner ear ischemia were found in the patients with sudden deafness. The using of vasodilator may have satisfactory and positive curative effect in the therapy of sudden deafness.

OBJECTIVETo observe the therapeutic effect of Xuefu Zhuyu Decoction (XZD) on patients with sudden deafness (SD).

METHODSSixty patients with SD were treated with XZD, and the changes of brainstem auditory evoked potential (BAEP) and transcranial Doppler (TCD) parameters in them were detected before and after treatment and analyzed statistically.

RESULTSI, III and V waveform and peak latency (PL) of BAEP, velocity of vertebral basilar arterial blood flow and parameters of cerebral blood flow in SD patients were all improved to different levels after treatment with XZD.

CONCLUSIONTCM formula for promoting blood circulation to remove blood stasis can improve BAEP and TCD parameters in SD patients; BAEP detection and TCD parameters can reflect nerve function and blood-supply state of internal ear and brain stem, and therefore are of great importance in guiding the clinical treatment and assessing the prognosis.
