Acute onset deafness with vestibular failure in the cervical syndrome could be due to embolism of the labyrinthine artery. Probably the symptomatology of the cervical syndrome developes independantly. Two patients with sudden deafness and vestibular failure are reported. Embolism of the labyrinthine artery in at least one of these patients appears to have occurred. The prognosis in respect of recovery of function is unfavourable.

To analyse the 3D-Flair MRI manifestations of the inner ear, vestibular function status, and their correlation with hearing treatment outcomes in patients with severe sudden sensorineural hearing loss (SSNHL), and to explore potential prognostic indicators for sudden deafness. The clinical data of adult patients with unilateral profound sudden sensorineural hearing loss were retrospectively analyzed in Otorhinolaryngology Department of Shandong Provincial ENT Hospital from March 2018 to August 2020. Patients were categorized based on the results of their inner ear 3D-Flair MRI into two groups: the normal MRI group and the abnormal MRI group.

An 11-year-old male Bengal tiger () was referred for a 2-week history of ambulatory tetraparesis, generalized ataxia, and hypermetric gait, associated with mild right head tilt and spontaneous proprioceptive deficit on the right forelimb. Neuroanatomical localization was C1-C5 myelopathy; cerebellum-vestibular system involvement was also considered. Hematology and serum biochemistry were unremarkable, although serum vitamin A (0.

To report a case of cochlear implantation with a misplaced electrode array in the vestibule and the causes for the delay in identification. A 23-year-old male with left single-sided deafness underwent cochlear implantation. The intraoperative assessment did not reveal any major red flags of electrode array misplacement.

Calcium and integrin-binding protein 2 (CIB2) and CIB3 bind to transmembrane channel-like 1 (TMC1) and TMC2, the pore-forming subunits of the inner-ear mechano-electrical transduction (MET) apparatus. These interactions have been proposed to be functionally relevant across mechanosensory organs and vertebrate species. Here, we show that both CIB2 and CIB3 can form heteromeric complexes with TMC1 and TMC2 and are integral for MET function in mouse cochlea and vestibular end organs as well as in zebrafish inner ear and lateral line.

Background: A vestibular implant can partially restore vestibular function by providing motion information through implanted electrodes. During vestibular implantation, various obstructions of the semicircular canals, such as protein deposits, fibrosis, and ossification, can be encountered. The objective was to explore the relationship between preoperative imaging and intraoperative findings of semicircular canal obstruction and to develop surgical strategies for dealing with obstructions of the semicircular canal(s) in patients eligible for vestibular implantation.
