We proposed a piezoelectric artificial basilar membrane (ABM) composed of microelectromechanical system cantilever array. The ABM mimics the tonotopy cochlea: frequency selectivity and mechanoelectric transduction. fabricated exhibits clear in an audible range (2.92-12.6 kHz). Also, animal model was used to verify characteristics as front end for potential cochlear implant applications. For this, signal processor convert output from electrical stimulus auditory neurons. neurons delivered...
Herniation of the temporomandibular joint (TMJ) into external auditory canal (EAC) is a very rare condition, and it mostly occurs in patients with bony wall defects anterior EAC. The purpose this study was to evaluate clinical radiological findings treatment results TMJ herniation EAC by reviewing large sample temporal bone computed tomography (CT) scans.A retrospective study.We reviewed 985 adult CT scans evaluated presence defects, size location herniation. We enrolled 23 cases...
Objectives: This study was conducted to examine improvements of cognitive abilities after cochlear implantation in deaf children. We also examined the psychosocial factors that predict good outcomes implantation. Design: A neuropsychological test battery administered 17 children (mean age, 7 yr 2 mo) before receiving implant, and they were reassessed with same at 6-mo follow-up. Their parents completed questionnaires concerning their medical educational history, parenting style, parental...
Compared with conventional cochlear electrode arrays, which are hand assembled and wire-based, polymer-based implants have several advantages. They very precise, their fabrication is inexpensive because of the use thin-film processes. In present study, a array based on high-performance liquid crystal polymer material devised. Furthermore, device encapsulated in silicone elastomer.The steps introduced here include processes (LCP) films customized self-aligning molding for array. To assess...
The dichotomy between acoustic temporal envelope (ENV) and fine structure (TFS) cues has stimulated numerous studies over the past decade to understand relative role of ENV TFS in human speech perception. Such produce distinct neural discharge patterns at level auditory nerve, yet little is known about central mechanisms underlying perception cues. We explored question how peripheral system encodes steady or fluctuating background noise, combines these forms information for identification....
This study was conducted to investigate long-term neurocognitive outcomes and determine associated risk factors in a cohort of Korean survivors childhood acute lymphoblastic leukemia (ALL). Forty-two ALL were compared with 42 healthy controls on measures test battery. We analysed potential (cranial irradiation, sex, age at diagnosis, elapsed time from group) outcomes. patients had lower, but non-significant full-scale intelligence quotient (FSIQ, 107.2±12.2 vs. 111.7±10.2), verbal (VIQ,...
The prevalence and age of onset hearing loss differ according to sex. This study aimed identify associated factors for age-related (ARHL) determine whether there are differences between males females regarding ARHL. cross-sectional used data from adults who underwent medical examinations including tests 2011 2021. A total 2,349 individuals were included. conducted sex-specific analyses using both univariate multiple regression. Univariate analysis employed logistic regression, while...
While the hazardous effects of microplastics (MPs) are increasingly reported, it remains uncertain if MPs induce inner ear dysfunction. Nonetheless, prevalence dysfunction was observed across all age groups. In this study, we investigated whether MP polyethylene affect function in a murine model. To detect hearing loss and balance defect after (PE) exposure, evaluated threshold levels, assessed cerebral glucose metabolism, conducted transcriptome analysis, performed behavioral studies....
Background Asthmatic nasal polyps primarily exhibit eosinophilic infiltration. However, the identities of immune cells that infiltrate non-asthmatic remain unclear. Thus, we thought to investigate distribution innate and its clinical relevance in chronic rhinosinusitis (CRS) Korea. Methods Tissues from uncinate process (UP) were obtained controls (n = 18) CRS without (CRSsNP, n 45). Nasal (NP) UP with (CRSwNP, 56). The was evaluated by immunohistochemistry such as, eosinophil major basic...
Superficial siderosis (SS) of the central nervous system has been thought to be a rare condition that generates progressive hearing loss, ataxia, pyramidal signs, and dementia. The main cause loss by SS is neuronal. Because there no histopathologic report human temporal bone in SS, debate about possibility cochlear involvement. We present 25-year-old man who was investigated for bilateral sensorineural vestibular failure after head trauma. On brain MRI, detected. Distortion product...
Conclusion. The incidence of ipsilesional beating vibration induced nystagmus (VIN) is significantly higher in Meniere's disease (MD) with lower canal paresis (CP) group on caloric test and the intensity VIN shows significant positive correlation CP. Considering previous reports showing predominant loss type II hair cells MD discrepancy results between head thrust patients, may provide valuable information regarding functional reservoir vestibular MD. Objectives. Clinical presentation...
