Targeted PCR Array Analysis of Genes in Innate Immunity and Glucocorticoid Signaling Pathways in Mice Cochleae Following Acoustic Trauma
Aim: To comprehensively analyze cochlear gene expressions related to innate immunity and glucocorticoid signaling at onset of acute noise-induced hearing loss (NIHL). Background: Recent studies suggested innate immunity is involved in the cochlear pathology of NIHL. Glucocorticoids may modulate immune actions in cochleae. Methods: Mice were exposed to 120 dB-octave band noise for 2 hours. Twelve hours later, a targeted PCR array analyzed cochlear expressions of 84 key genes in inflammation and immune pathways and 84 genes in the glucocorticoid signaling pathway. Real-time RT-PCR was used to analyze expression of ...

Intracochlear Pressures in Simulated Otitis Media With Effusion: A Temporal Bone Study
Conclusion: Simulating effusion leads to a frequency-dependent reduction in intracochlear sound pressure levels consistent with audiological presentation and prior reports. Results reveal that intracochlear pressure measurements (PSV and PST) decrease less than expected, and less than the decrease in PDiff. The observed decrease in umbo velocity is greater than in the differential intracochlear pressures, suggesting that umbo velocity overestimates the induced conductive hearing loss. These results suggest that an alternate sound conduction pathway transmits sound to the inner ear during effusion. (Source: Otology and Neurotology)

Is an Intravenous Injection of Gadolinium Really Necessary for Intralabyrinthine Schwannomas MR Examination?
Conclusion: The positive and topographic diagnostic accuracy of T2W FIESTA-C sequence was excellent compared with the T1W contrast-enhanced sequence, even though the latter remains easier and faster to analyze for an untrained radiologist. The performances of T2W gradient-echo sequence at 3T make it a reasonable alternative strategy for following ILS after they are diagnosed. (Source: Otology and Neurotology)

Cochlear Patency After Translabyrinthine Vestibular Schwannoma Surgery
Conclusion: Cochlear signal changes suggestive of fibrosis occurred in most patients following translabyrinthine removal of vestibular schwannoma. Given the early onset of cochlear fluid signal changes on T2MRI, and the progression of these changes on subsequence imaging, cochlear implantation would ideally need to be performed either simultaneous to translabyrinthine surgery or as an early second-stage procedure to maximize the chance of a successful electrode insertion, or one can consider a placeholder as well.

Validation of Posturographic Measurements in Adolescents
Conclusion: The most reliable and least variable measurements include position NO, NC, PO, and PC. Influence of all three systems involved in maintaining balance is tested in these positions. Static posturography can easily be implemented in a clinical setting as the equipment does not take up much space and is easy to use and instruct the test subjects about. Finally, the costs related to the static posturography are considerably lower compared with dynamic posturography equipment. However, static posturography might not be challenging enough when testing athletic individuals. (Source: Otology and Neurotology)

Ocular and Cervical Vestibular Evoked Myogenic Potentials in Patients With Vestibular Migraine
Conclusion: Patients with VM are more likely than subjects with vestibular disorders other than migraine to exhibit normal cVEMP responses in the presence of unilaterally abnormal oVEMP responses. Such a VEMP pattern may be a biomarker of VM and further supports a possible pathophysiologic relationship between the utriculo-ocular reflex and VM. (Source: Otology and Neurotology)

Conclusion: The implementation of EMNS in SEA cochlear implantation added additional safety to the procedure, which resulted in full electrode insertion and superior AP. Yet, outcome in cochlear implantation may vary. Larger case series to confirm this observation are required. The approach proposed for EMNS-guided SEA in this case report, using commercially available EMNS, may lead to a more frequent implementation in clinical routine due to its good clinical feasibility.

Changes to Hearing Levels Over the First Year After Stapes Surgery: An Analysis of 139 Patients
Background: Stapes surgery is performed for hearing restoration in patients with otosclerosis. Results from stapes surgery are good, although a small proportion will have a persistent conductive hearing loss and will consider revision surgery.

Conclusions: These results suggest that children living in remote communities can be screened quickly for hearing loss using a tablet audiometer.

Despite extending the reach of existing audiological services, the value of tablet audiometry is not entirely clear in rural environments with uncontrollable background noise.

Hearing Changes After Intratympanic Steroids for Secondary (Salvage) Therapy of Sudden Hearing Loss: A Meta-Analysis Using Mathematical Simulations of Drug Delivery Protocols
Conclusion: Based on the available data from uncontrolled and controlled randomized and non-randomized studies no clear recommendation can be made so far for a specific application protocol for either primary or secondary (salvage) intratympanic steroid treatment in patients with ISSHL. For meta-analyses, change in pure tone average (PTA) may not be an adequate outcome parameter to assess effectiveness of the intervention especially with inhomogeneity of patient populations. Final PTA might provide a better outcome parameter. (Source: Otology and Neurotology)

Clinical Implications of the Association Between Temporal Bone Tegmen Defects and Superior Semicircular Canal Dehiscence
Conclusion: The close proximity of a TD and an SSCD might not allow selective exposure. As a result, asymptomatic SSCD may become symptomatic during TD correction via the temporal craniotomy approach. The need to plug an asymptomatic SSCD that is proximal to a TD should be factored in planning for surgery and rehabilitation. The choice of surgical approach (middle fossa vs. transmastoid) could be influenced by this relationship, especially in cases of bilateral lesions. (Source: Otology and Neurotology)

Vestibular Function and Hippocampal Volume in the Baltimore Longitudinal Study of Aging (BLSA)
Conclusions: Lower cVEMP amplitude (i.e., reduced saccular function) was significantly associated with lower mean hippocampal volume. This is in line with previous work demonstrating a link between saccular function and spatial cognition. Hippocampal atrophy may be a mechanism by which vestibular loss contributes to impaired spatial cognition in older adults. Future work using longitudinal data will be needed to evaluate the causal nature of the association between vestibular loss and hippocampal atrophy. (Source: Otology and Neurotology)
