“…Vestibular neuritis is the most common cause of vertigo after Benign Positional Paroxysmal Vertigo. 13 Vertigo is not a disease alone, it is the main symptom of different diseases with varying etiology and it is a disease of brain stem, inner ear, cerebellum or psychic origin. It may result from side effects of drugs such as antihypertensive, anticonvulsive or orthostatic disorder.…”

Aim: Vestibular neuritis is one of the most common causes of acute spontaneous vertigo. In our study, we aimed to analyze the cerebellum volume and cerebellum connections in patients diagnosed with vestibular neuritis using the VolBrain program. Materials and Methods: 10 patients and 9 healthy (control) persons were included in the study. Automatic segmentation and volumetric analysis of cerebellum and cerebellum lobules were investigated using magnetic resonance images (MRI) of 19 people. Results: The volumes of 10 cerebellar regions were measured and compared between the patient and control groups. The total volume of the cerebellum was calculated as 123.82 ± 2.57 cm3 in the control group and 119.97 ± 4.15 cm3 in the patient group. In addition, the average amount of gray matter in the cerebellum was 90.63 ± 6.59 cm3 in the control group and 87.87 ± 16.12 cm3 in the patient group. We found volumetric changes to be statistically significant. Conclusion: By performing cerebellum segmentation with 3D T1 sequence of MRI images taken from patients diagnosed with vestibular neuritis, volume measurement and more detailed examinations can be performed easily with the help of the volBrain program. Moreover, its low cost and its usefulness in diagnosis suggest that this method will be beneficial.

“…Similarly, contrastenhanced FLAIR sequence acquired at 1.5 T, 1 h after intravenous gadolinium injection, appeared useful to diagnose acute vestibular neuritis (Fig. 5)with or without hyperintens inflammatory signal of the ampullae [18]. In acute vestibular neuritis, enhancement of the superior vestibular nerve (> 71.5 units) was observed on the pathological side in 85% of the cases of vestibular neuritis.…”

“…Using this sequence, Venkatasamy et al [20] also described an enlargement of the saccule in 46% of the cases of cochlear intralabyrinthine schwannomas. Seemingly, the contralateral enlargement of the saccule, observed in 16% of internal auditory canal vestibular schwannomas, was also observed in 37% of the cases of cochlear intralabyrinthine schwannomas [18].…”

“…Therefore, the analysis of the perilymphatic signal was an effective additional tool to differentiate cerebellopontine angle meningiomas from schwannomas, as the decrease of the perilymphatic signal was more moderate in obstructive meningiomas than in obstructive schwannomas [6,19]. The endolymphatic signal remained normal regardless of the tumor type [18]. In addition to changes of signal intensity of posterior membranous structures in the presence of VS, Karch-Georges et al [7] observed changes in size/shape.…”

OBJECTIVE: Part of the recent progress in the labyrinth imaging has been made possible by the rise of contrast-free T2-weighted and delayed (1h) FLAIR sequences. The aim of this article is to review evidence for the use of these two sequences to image the inner ear, especially the posterior membranous labyrinth. MATERIAL AND METHODS: We analyzed MRI-based papers (2007–2020)using high-resolution T2-weighted or contrast-enhanced FLAIR (1h) sequences to image the inner ear. RESULTS: T2-weighted sequences (3T MRI)enabled the visualization of the posterior membranous labyrinth with good correlation when compared to corresponding histological slices.Significant progress has been made, especially in terms of scanning time, aiming at reducing it, in order to decrease motions artifacts. The saccule is visible on a 3T MRI without significant motion artifacts. Its shape is ovoid, with a maximum height and width of 1.6 and 1.4 mm, respectively. An enlarged saccule was observed in 84%of patients with unilateral Meniere’s disease, in 28%of patients with vestibular schwannomas (VS) and 47%of patients with intralabyrinthine schwannomas. VS obstructing the internal auditory canal caused a decrease of the perilymphatic signal (more moderate decrease in meningiomas) on T2 gradient-echo images. Contrast-enhanced FLAIR sequences are useful to image vestibular/facial neuritis and inflammatory inner ear diseases. CONCLUSION: Precise analysis of the posterior membranous labyrinth, in terms of size, shape and signal intensity, is possible on a 3T MRI using high-resolution gradient-echo T2-weighted sequences. Such sequences are an interesting add-on to delayed (4h30) FLAIR-based protocols for labyrinth imaging.

This study aimed to explore the effect of health education combined with psychological care on patients with vestibular neuritis and the effect on their vestibular function. One hundred patients with vestibular neuritis admitted to our hospital from January 2019 to December 2020 were enrolled and divided into two groups by the random number: the control group (CG) (n= 53, health education) and the study group (SG) (n= 47, health education + psychological care). The Dizziness Handicap Inventory (DHI) scores, Berg Balance Scale (BBS) scores, depression scores (SDS), anxiety scores (SAS), satisfaction with care, compliance, incidence of falls, quality of life (QOF), and clinical symptom scores were compared between the two groups. Compared with the CG, the SG had a more significant reduction in DHI scores and SDS and SAS scores and a significant increase in BBS scores ( P < 0.05 ). Compared with the CG, the SG had higher nursing satisfaction and compliance and a lower incidence of falls ( P < 0.05 ). Nursing efficiency was higher in the SG than in the CG ( P < 0.05 ). QOF scores were higher in the SG than in the CG ( P < 0.05 ). Clinical symptom scores were lower in the SG than in the CG ( P < 0.05 ). Health education combined with psychological care can improve vestibular function and bad mood, reduce the incidence of falls, improve the QOF, and result in high patient satisfaction and compliance, which should be widely promoted.
