This standard method for the development of middle ear implants requires temporal bones that possess appropriate mechanical properties and structural stability and are free from pathological conditions. A laser Doppler vibrometer is commonly employed to measure the vibration of the stapes footplate. These experiments are typically conducted in the middle ear by leaving the inner ear intact, exposing the stapes footplate through the tympanic cavity, and directing the laser beam onto the footplate. However, previous studies have shown that the influence of inner ear impedance on the middle ear transfer function cannot be ignored, and any surgical manipulation may cause a change in inner ear pressure, resulting in instability in the middle ear transfer function. Therefore, this study aims to eliminate the influence of the inner ear and to establish a new experimental method in human temporal bone specimens that is more suitable for the study of sound conduction in middle ear implants. As a result, a range for middle ear transfer function was developed, which serves as a reference for assessing the conformity of temporal bone specimens to experimental standards, and the stability of this range was demonstrated under experimental conditions.</p>","PeriodicalId":94336,"journal":{"name":"Journal of otology","volume":"20 4","pages":"219-224"},"PeriodicalIF":0.0,"publicationDate":"2025-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12647957/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145644221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advances in regenerative medicine have led to increased interest in stem cell therapy as a potential solution for auditory restoration. Research on embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and mesenchymal stem cells (MSCs) has demonstrated their ability to differentiate into auditory cell types, offering a potential avenue for cochlear regeneration. Gene therapies also present a promising approach for addressing hereditary hearing loss by targeting specific genetic mutations. iPSCs in particular show promise, especially when combined with gene therapy for hereditary hearing loss. Despite encouraging preclinical findings, persistent hurdles remain: immune rejection, limited cell survival, difficulty with cochlear integration, and complex ethical and regulatory considerations. Addressing these barriers is crucial for safe and effective translation into clinical care. In Pakistan, there is a critical need to promote advancements in this field.

While some individuals experience spontaneous recovery, the unpredictability of treatment outcomes and potential complications pose clinical challenges. Recent studies suggest a potential link between thyroid hormone levels-particularly free triiodothyronine (FT3) and thyroid-stimulating hormone (TSH)-and both the pathogenesis and prognosis of SSNHL. However, the precise mechanisms remain unclear. This study aims to investigate the correlation between thyroid hormone abnormalities and hearing recovery in SSNHL patients, providing insights to enhance diagnostic and therapeutic approaches.</p><p><strong>Methods: </strong>This prospective observational study included 66 SSNHL patients admitted to the Affiliated Hospital of Qingdao University between April 2024 and February 2025. Serum TSH and FT3 levels were measured using chemiluminescence immunoassay, while hearing function was evaluated through pure-tone audiometry following standard guidelines.

However, during treatment, ΔFT3 demonstrated a significant negative correlation with PTHG (r = -0.739, p = 0.002), suggesting that a greater increase in ΔFT3 is associated with improved hearing recovery.

However, dynamic changes in FT3 during treatment showed a significant correlation with therapeutic efficacy, suggesting that monitoring ΔFT3 may have clinical value in prognostic assessment.
