Introduction: In a previous manuscript from our research group, the concept of vestibular co-stimulation was investigated in adult subjects who received a cochlear implant (CI). Despite what literature reports state, no signs of vestibular co-stimulation could be observed.

Results: In this case report, it was described how a woman, who previously underwent a neurectomy of the left vestibular nerve and suffers from bilateral vestibulopathy (BVP), reported improved balance whenever her CI on the left was stimulating.

Purpose: The classical surgical approach for superior semicircular canal dehiscences (SSCD) is via the extradural middle cranial fossa. This pathway is used to resurface or to plug the SSC. In this paper, we present long-term data on an alternative route: the transmastoid pathway.

Article Synopsis
  • A study was conducted to compare the effectiveness of two MRI techniques, 3D-SPACE FLAIR and 3D-TSE FLAIR, in detecting Menière's disease (MD) by focusing on endolymphatic hydrops (EH) visualization and perilymphatic enhancement (PE).
  • The research involved analyzing MR images from 29 patients with definite MD, assessing both qualitative (EH grading and PE comparison) and quantitative (PE ratio calculation) aspects.
  • Results showed that 3D-SPACE FLAIR had greater sensitivity (91%) and diagnostic accuracy for detecting EH and PE than 3D-TSE FLAIR, indicating it may be a better tool for diagnosing MD.

Purpose: In this retrospective study the relationship between cochleovestibular function and a magnetic resonance imaging (MRI-) based classification system of endolymphatic hydrops was investigated.

Methods: Seventy-eight patients with unilateral definite Menière's disease who underwent MRI were included. The parameters of Pure Tone Audiometry (PTA), caloric irrigation test, cervical vestibular evoked myogenic potentials, and video Head Impulse Test were compared between the grades of endolymphatic hydrops (EH) and perilymphatic enhancement (PE) on MRI.

Purpose: There is still a clinical-radiologic discrepancy in patients with Menière's disease (MD). Therefore, the purpose of this study was to investigate the reliability of current MRI endolymphatic hydrops (EH) criteria according to Baráth in a larger study population and the clinical utility of new imaging signs such as a supplementary fourth low-grade vestibular EH and the degree of perilymphatic enhancement (PE) in patients with Menière's disease (MD).

Methods: This retrospective study included 148 patients with probable or definite MD according to the 2015 American Academy of Otolaryngology, Head and Neck Surgery criteria who underwent a 4-h delayed intravenous Gd-enhanced 3D-FLAIR MRI between January 2015 and December 2016.

Vestibular signals are of significant importance for variable functions including gaze stabilization, spatial perception, navigation, cognition, and bodily self-consciousness. The vestibular network governs functions that might be impaired in patients affected with vestibular dysfunction. It is currently unclear how different brain regions/networks process vestibular information and integrate the information into a unified spatial percept related to somatosensory awareness and whether people with recurrent balance complaints have a neural signature as a trait affecting their development of chronic symptoms of vertigo.

Background: The DHI is a widely used questionnaire for the evaluation of the self-reported disability in patients with dizziness and balance problems.

Objective: To investigate the relationship between the DHI scores and demographic, symptomatic and diagnostic parameters.

Methods: Retrospective study in 568 patients with balance problems.

The site of stimulus delivery modulates the waveforms of cervical- and ocular vestibular-evoked myogenic potentials (cVEMP and oVEMP) to skull taps in healthy controls. We examine the influence of stimulus location on the oVEMP waveforms of 18 patients (24 ears) with superior canal dehiscence (SCD) and compare these with the results of 16 healthy control subjects (32 ears). oVEMPs were recorded in response to taps delivered with a triggered tendon-hammer and a hand-held minishaker at three midline locations; the hairline (Fz), vertex (Cz) and occiput (Oz).

Objective: Transcranial magnetic stimulation (TMS) is already broadly used in different areas of neuroscience research. In the last years, special attention was drawn to TMS in tinnitus. The aim of our study is to investigate the stimulation characteristics of TMS in tinnitus patients, in particular the effect of tonic and burst stimulation of the superior temporal lobe.

Superficial hemosiderosis of the central nervous system (SH-CNS) is a relatively rare condition caused by chronic or repeated subarachnoid bleeding. The aim of this article was to present hearing disorders related to SH-CNS, and to describe results of magnetic resonance imaging (MRI) to confirm the diagnosis. We performed a retrospective case review at a tertiary referral center.

Intrasphenoidal meningoencephalocele is a rare clinical entity. Its origin can be congenital, traumatic, tumoral, or spontaneous. Presenting as cerebrospinal fluid fistula with rhinorrhea, the diagnosis and treatment of this uncommon disease is a real challenge for the otorhinolaryngologist.

Although pilomatrixomas are well known among dermatologists and dermatopathologists, head and neck surgeons confronted with these lesions in the infra-auricular region do not consider this benign neoplasm in the differential diagnosis. Aggressive pilomatrixoma is a benign tumor of the hair matrix cells affecting mainly children. Histologically, the border between aggressive pilomatrixoma and pilomatrix carcinoma is still not clear.

Myositis ossificans circumscripta (MOC) is a benign condition of heterotopic bone formation that remains difficult to distinguish from soft-tissue and bone malignancies. We describe an unusual case of non-traumatic MOC in the cervical paraspinal muscle. The diagnosis could only be established after surgery and histological examination.
