We propose that simplification of the Eustachian tube's structure may represent a crucial step toward elucidating the mechanisms underlying intraluminal pressure variation. In the present study, simplified models were constructed from CT scans of patients with patulous Eustachian tube. These models captured the tube's key morphological features, including a blind-ended tubular structure with a sealed tympanic orifice, an open pharyngeal orifice, and a deformable central segment. Particle image velocimetry (PIV) was used to enable visualization of flow field alterations within the lumen during the transition from a closed to an open state under various simulated middle ear pressure conditions. The following phenomena were observed: (1) Bidirectional pumping at the onset of intraluminal negative pressure, characterized by simultaneous suction from both sides toward the center; (2) Variation of the pumping phenomenon under different middle ear pressure conditions; (3) Vortex generation at the tympanic orifice upon tubal opening under middle ear negative pressure.

Optical coherence tomography (OCT) vibrometry has been used to examine the simultaneous motions of OC structures, including the basilar membrane (BM), outer hair cells (OHCs) and reticular lamina (RL), with gerbil and guinea pig (GP) as common animal models. Boosting (motion responses larger than passive motion), and nonlinearity at frequencies below the best frequency (sub-BF) are a robust observation within the gerbil OHC-region. Fallah et al. (2021) compared basal OC mechanics between gerbil and GP and found that GP OC motions at sub-BF frequencies were generally less boosted and showed less nonlinearity than those in gerbil. In the present work, we expand upon the GP measurements by measuring intra-OC motion through both the round window (RW) and a basal cochleostomy in the same experiment. We found substantial differences in the motions when measured through the RW versus the cochleostomy. In the OHC/Deiters Cell(DC) region, sub-BF nonlinearity and boosting were present in measurements through a cochleostomy, but not through the RW. A mild degree of sub-BF nonlinearity was present in the RL region in RW measurements, but not through the cochleostomy. The discussion proposes hypotheses for these differences, including optical angle dependency and mechanical perturbation. Finally, a complex difference analysis was used to extract the internal motion of OC structures riding on the BM motion. The stimulus-level-dependence of the internal OC motions was reduced in the phase responses and increased in the amplitude responses compared to the directly measured OC motion, and irregularities such as nonmonotonic scaling in the measured motion were not present in the extracted internal motion.</p>","PeriodicalId":12881,"journal":{"name":"Hearing Research","volume":"468 ","pages":"109449"},"PeriodicalIF":2.5,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145312755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of particular concern is exposure during critical periods of neurodevelopment, which has been associated with long-lasting effects on sensory systems, including auditory processing. This review elaborates findings from both human epidemiological studies and animal models to examine the effects of PCBs on auditory function across the peripheral and central auditory pathways. Evidence indicates that PCB exposure during gestation and early postnatal life can lead to permanent auditory deficits. At the level of the auditory periphery, reductions in distortion-product otoacoustic emissions (DPOAEs) and auditory brainstem responses (ABRs) suggest cochlear outer hair cell dysfunction, potentially mediated by oxidative stress. Centrally, alterations in the primary auditory cortex and inferior colliculus have been observed, including disrupted tonotopic organization, excitation–inhibition imbalance, and impaired neuroplasticity. Notably, such central neural changes can occur out of proportion to abnormalities in ABRs, pointing to central auditory vulnerabilities. Epidemiological data in humans further support these findings, with certain PCB congeners linked to a significantly elevated risk of hearing impairment in children. PCB exposure coupled with loud noise exposure, which is growing in prevalence, leads to cumulative deficits in auditory processing. Together, these findings highlight the multi-level impact of PCB exposure on the auditory system and highlight the need for further investigation into the molecular and circuit-level mechanisms underlying these effects. Understanding the actions of PCB congeners on the auditory system in various human population cohorts is important to inform risk assessment and guide future public health policies.</div></div>","PeriodicalId":12881,"journal":{"name":"Hearing Research","volume":"467 ","pages":"Article 109442"},"PeriodicalIF":2.5,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145250851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
