Summary: This study investigated the effects of SC plugging on inner ear fluid space using a novel 3D reconstruction-based method. Results showed significant differences in volume changes between the success and failure groups, indicating a correlation between 3D volume changes and the outcomes of SC plugging.

Summary: This study evaluated the gain and refixation saccades in patients with acute vestibular neuritis using the vHIT test. It found that the gain was significantly lower on the affected side, mainly in the horizontal canal plane, and saccades were more prevalent in the horizontal canal plane. At follow-up, the gain was recovered in all canals, while saccades were reduced in both horizontal and vertical planes.

Summary: The study evaluated the evolution of vestibular function and hearing after plugging of a semicircular canal, showing that most patients experience recovery during follow-up, but some may persist with vestibular function loss or high-frequency hearing loss.

Summary: Implementing natural encoding strategies improves the performance of vestibular prosthesis, while more dynamic tunings may not be beneficial. Using computational methods, a simple model can explain eye movements evoked by different stimulation modes, and the activation efficacy should be considered in prosthesis encoding. These findings are important for improving functional outcomes in prosthesis development.

Summary: This study retrospectively analyzed preoperative vestibular function tests in patients with vestibular schwannoma (VS) to determine the value of these tests in predicting tumor origin. The results suggest that the gain of vestibular-ocular reflex (VOR) in the ipsilesional posterior canal (iPC) during the video head impulse test (vHIT) may be a useful indicator of nerve origin in patients with VS, especially in cases of medium to large tumors. Other cochleovestibular function tests have limited value in discriminating nerve origins.

Summary: This study aimed to determine the findings of video head-impulse tests in patients with posterior circulation strokes (PCSs) and vestibular neuritis (VN). The results showed that patients with PCS exhibited more diverse video head-impulse test responses compared to VN, including normal, contralaterally positive, and negative saccadic amplitude asymmetry. Thorough analysis of corrective saccades in video head-impulse tests can improve the differentiation of PCS and VN even before MRIs.

Summary: Postural instability is a common symptom of vestibular dysfunction, and vestibular rehabilitation through virtual reality methods has the potential to significantly improve postural control and reduce dizziness and visual symptoms. This research aims to develop a novel protocol using off-the-shelf sensors and custom instrumentation to assess and improve vestibular-postural control in neurological populations. The findings could have important implications for future vestibular rehabilitation protocols.

Summary: This study aims to describe the factors that may lead to residual function after plugging a symptomatic dehiscent superior semicircular canal (SSCC). The length and location of the dehiscence can be useful indicators for predicting disease symptomatology preoperatively and canal function recovery after plugging.

Summary: This study retrospectively analyzed 6 patients with isolated (hemi)nodular strokes and conducted comprehensive neuro-otological assessments. The study found that the patients had normal horizontal and vertical vestibulo-ocular reflex (aVOR) function but exhibited various ocular motor abnormalities and postural control issues.

Summary: The main objective of this study is to assess the feasibility and performance of eye and head movement measurements during virtual reality head impulse test (VR-HIT) under normal and altered visual feedback conditions. The results showed successful recording of eye and head motion during both normal and altered conditions. The VR setup used in this study can provide high-quality data for investigating compensation mechanisms in vestibular hypofunction, eliciting adaptation of vestibuloocular reflex, and evaluating VR-based vestibular rehabilitation objectively.

Summary: This study investigated the effects of SARS-CoV-2 on the audiovestibular system in different patient groups. The results suggest that SARS-CoV-2 may affect the vestibulocochlear system, but there is no direct relationship to the severity of the disease.

Summary: This study explores whether the vestibulo-ocular reflex (VOR) gain changes in response to a clinical headshake maneuver in patients with vestibular migraine (VM). The study found that there was no significant change in VOR gain after headshaking in any group. Patients who reported nausea when reading in the passenger seat of a car were more likely to have VM.

Summary: Acute unilateral vestibular hypofunction presents with sudden onset of vertigo, nausea/vomiting, gait instability, and nystagmus, commonly attributed to vestibular neuritis or stroke. The video head impulse test is a valuable tool for evaluating vestibular function.

Summary: Gaze stabilization relies on bilateral mirror-symmetric vestibular endorgans, central circuits, and extraocular motor effectors. The study found that significant motor outputs can develop even in the presence of a singular inner ear. Surprisingly, robust vestibulo-ocular reflexes were observed in most cases, regardless of the direction of motion, but they were often attenuated during motion towards the missing ear.
