Objectives: A primary reason for the low adoption of hearing aids (HAs) among the large population with sensorineural hearing loss is the perception that these devices may negatively impact remaining hearing ability. Research addressing this issue has yielded conflicting results. This study examined the long-term effects of HAs on standard audiometric changes in individuals with sensorineural hearing loss.
Methods: We retrospectively analyzed patients who acquired unilateral HAs between 2015 and 2017 and demonstrated consistent use over a 5-year period. We examined demographics, medical comorbidities, audiometric data, and questionnaire results from the Hearing Handicap Inventory for the Elderly and the International Outcome Inventory for Hearing Aids. Additionally, we reviewed each patient's history of noise exposure and prior HA use.
Results: The study included 55 patients who used unilateral HAs, with a mean follow-up period of 5.32 years. Among them, 31 patients (56.4%) used the HA on the right side. Audiometric data from the aided side showed no significant difference from the unaided side in either the pre-fit pure-tone average of air conduction (AC) or word recognition score (WRS) (P =0.73 and P =0.11, respectively). Similarly, no significant differences were noted in the 5-year follow-up audiometry of AC and WRS (P=0.98 and P=0.07, respectively) or in the change from pre-fit to final audiometry for either parameter (AC, P=0.58; WRS, P=0.70). Eleven patients (20%) exhibited a deterioration in hearing (as measured by AC) of 5 dB or greater on the aided side compared with the unaided side, while 23 (53.5%) showed greater WRS deterioration on the aided side. No significant factors were found to contribute to the difference in hearing deterioration between groups for either AC or WRS.
Conclusion: No significant factors were identified as contributing to hearing deterioration after prolonged HA use. Overall, the use of HAs did not adversely impact residual hearing.
目的:在众多感音神经性听力损失患者中,助听器(HA)采用率不足的主要原因之一是社会担心助听器可能会对剩余听力能力产生负面影响。迄今为止,关于这一问题的研究很少,结果也存在争议。本研究探讨了助听器对感音神经性听力损失患者标准听力变化的长期影响:研究回顾性分析了 2015 年至 2017 年间新获得单侧 HA 并显示持续使用五年的患者。研究对象包括人口统计学、合并症、听力数据、老年人听力障碍量表(HHIE)和国际助听器结果量表(IOI-HA)的问卷调查结果、噪声暴露史以及之前使用过助听器:55 名患者使用了单侧助听器,平均随访时间为 5.32 年。31名患者(56.4%)在右侧使用助听器。受助侧的听力数据与未受助侧相比,在矫治前的纯音平均气导(AC)和单词识别分数(WRS)(P= 0.73,0.11,分别为0.73和0.11)、AC和WRS的五年随访听力(P=0.98,0.07)或AC和WRS从最后一次到矫治前的听力变化(P=0.58,0.70)方面均无显著差异。如果将助听侧与非助听侧听力下降 5 分贝或更多的患者进行比较,有 11 名患者(20%)的助听侧 AC 出现恶化,23 名患者(53.5%)的助听侧 WRS 出现进一步恶化。两组患者在 AC 或 WRS 方面的听力恶化差异均无明显因素:结论:长期使用助听器后,听力恶化没有明显的诱因,总体而言,助听器的使用不会对残余听力产生负面影响。

Objectives: The distribution and extent of excitable spiral ganglion neurons (SGNs) have been investigated using the electrically evoked auditory brainstem response (EABR) during preoperative and perioperative periods. In this study, we investigated the EABR with extracochlear stimulation (eEABR) as a preoperative test to estimate these factors.
Methods: Sixteen male Sprague-Dawley rats were used in this study. Experiments were conducted in nine rats with normal hearing and seven rats that were partially deafened with ouabain treatment. Each experiment involved the following steps: extracochlear stimulating electrode placement at three different sites along the axis of the cochlea and eEABR recordings; cochleostomy and four-channel intracochlear array implantation, followed by EABR recordings with various electrode pair combinations; and after electrophysiological measurements, harvest of the cochleae for histopathological evaluation. The slope characteristics of the amplitude growth function measured from eEABR and EABR, frequency-specific auditory thresholds, and the density of SGNs were compared.
Results: Similar trends were observed in slope changes on different sites of stimulation with both types of stimulation in normal-hearing animals-specifically, a monotonically increasing slope with increasing distance between bipolar pairs. In addition, eEABR slopes showed significant correlations with EABR slopes when the expected cochlear regions of stimulation were similar in normal-hearing animals. In partially deaf animals, the auditory thresholds at several frequencies had a significant correlation with the eEABR slopes of each extracochlear electrode at the apical, middle, and basal cochlear positions. This indicated that increasing the regions of cochlear stimulation had a differential impact on eEABR slopes, depending on the neural conditions.
Conclusion: Our results indicated that eEABR slopes showed significant spatial correlations with the functionality of the auditory nerve. Therefore, eEABR tests at various cochlear positions might be used for estimating the extent of excitable SGNs in cochlear implant candidates prior to implantation.

Cochlear hair cells convert sound into electrical signals that are relayed via the spiral ganglion neurons to the central auditory pathway. Hair cells are vulnerable to damage caused by excessive noise, aging, and ototoxic agents. Non-mammals can regenerate lost hair cells by mitotic regeneration and direct transdifferentiation of surrounding supporting cells. However, in mature mammals, damaged hair cells are not replaced, resulting in permanent hearing loss. Recent studies have uncovered mechanisms by which sensory organs in non-mammals and the neonatal mammalian cochlea regenerate hair cells, and outlined possible mechanisms why this ability declines rapidly with age in mammals. Here, we review similarities and differences between avian, zebrafish, and mammalian hair cell regeneration. Moreover, we discuss advances and limitations of hair cell regeneration in the mature cochlea and their potential applications to human hearing loss.

Objectives: The recent expansion of eligibility for cochlear implantation (CI) by the U.S. Food and Drug Administration (FDA) to include infants as young as 9 months has reignited debates concerning the clinically appropriate cut-off age for pediatric CI. Our study compared the early postoperative trajectories of receptive and expressive language development in children who received CI before 9 months of age with those who received it between 9 and 12 months. This study involved a unique pediatric cohort with documented etiology, where the timing of CI was based on objective criteria and efforts were made to minimize the influence of parental socioeconomic status.
Methods: A retrospective review of 98 pediatric implantees recruited at a tertiary referral center was conducted. The timing of CI was based on auditory and language criteria focused on the extent of delay corresponding to the bottom 1st percentile of language development among age-matched controls, with patients categorized into very early (CI at <9 months), early (CI at 9-12 months) and delayed (CI at 12-18 months) CI groups. Postoperative receptive/expressive language development was assessed using the Sequenced Language Scale for Infants receptive and expressive standardized scores and percentiles.
Results: Only the very early CI group showed significant improvements in receptive language starting at 3 months post-CI, aligning with normal-hearing peers by 9 months and maintaining this level until age 2 years. During this period (<2 years), all improvements were more pronounced in receptive language than in expressive language.
Conclusion: CI before 9 months of age significantly improved receptive language development compared to later CI, with improvements sustained at least up to the age of 2. This study supports the consideration of earlier CI, beyond pediatric Food and Drug Administration labeling criteria (>9 months), in children with profound deafness who have a clear deafness etiology and language development delays (<1st percentile).
目的:最近,美国食品和药物管理局(FDA)将人工耳蜗植入(CI)的资格扩大到 9 个月大的婴儿,这再次引发了关于小儿 CI 临床合适截止年龄的争论。我们的研究旨在比较 9 个月前和 9 至 12 个月之间植入人工耳蜗的婴儿术后早期接受/表达语言发展的轨迹,这些婴儿的病因有据可查,植入人工耳蜗的时机是根据客观标准决定的,同时尽量减少父母的社会经济影响:方法:对一家三级转诊中心招募的 98 名儿科植入者进行了回顾性审查。CI 时机的选择以听觉和语言标准为基础,重点关注与最低百分位数相对应的发育迟缓程度:只有极早期 CI 组从 CI 后 3 个月开始在接受性语言方面有明显改善,到 9 个月时与听力正常的同龄人一致,并将这一水平保持到两岁。在此期间(结论:与较晚植入的 CI 相比,9 个月前植入的 CI 能明显促进接受性语言的发展,至少能维持到 2 岁。这项研究支持对有明确耳聋病因和语言发育迟缓的重度耳聋儿童,在超出儿科 FDA 标签标准(大于 9 个月)的情况下,考虑更早地植入 CI。

Objectives: The necessity to develop a method for prognostication and to identify novel biomarkers for personalized medicine in patients with head and neck squamous cell carcinoma (HNSCC) cannot be overstated. Recently, pathomics, which relies on quantitative analysis of medical imaging, has come to the forefront. CXCL8, an essential inflammatory cytokine, has been shown to correlate with overall survival (OS). This study examined the relationship between CXCL8 mRNA expression and pathomics features and aimed to explore the biological underpinnings of CXCL8.
Methods: Clinical information and transcripts per million mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA)-HNSCC dataset. We identified correlations between CXCL8 mRNA expression and patient survival rates using a Kaplan-Meier survival curve. A retrospective analysis of 313 samples diagnosed with HNSCC in the TCGA database was conducted. Pathomics features were extracted from hematoxylin and eosin-stained images, and then the minimum redundancy maximum relevance, with recursive feature elimination (mRMR-RFE) method was applied, followed by screening with the logistic regression algorithm.
Results: Kaplan-Meier curves indicated that high expression of CXCL8 was significantly associated with decreased OS. The logistic regression pathomics model incorporated 16 radiomics features identified by the mRMR-RFE method in the training set and demonstrated strong performance in the testing set. Calibration plots showed that the probability of high gene expression predicted by the pathomics model was in good agreement with actual observations, suggesting the model's high clinical applicability.
Conclusion: The pathomics model of CXCL8 mRNA expression serves as an effective tool for predicting prognosis in patients with HNSCC and can aid in clinical decision-making. Elevated levels of CXCL8 expression may lead to reduced DNA damage and are associated with a pro-inflammatory tumor microenvironment, offering a potential therapeutic target.

Objective. With rapid innovation in and expanding indications for cochlear implantation (CI), changes in the features of revision CI (RCI) appear to be emerging. This study aims to investigate the changes in RCI profile and discuss their clinical significance. Methods. A retrospective chart review was performed for all CIs performed at a tertiary medical institution between October 2001 and January 2023. The rate and reasons for RCI were evaluated and examined in terms of the manufacturer and device model. The Kaplan-Meier curve was used to examine the cumulative and device survival curves. In addition, the cumulative and device survivals were further analyzed based on age group, time period of primary CI, and manufacturer. Cox proportional hazards model was used to evaluate the association between RCI and manufacturers. Results. Among 1,430 CIs, 73 RCIs were conducted (5.1%). Device failure was the most common cause of RCI (40 of 73 RCIs [54.8%]), with an overall device failure rate of 2.8%, followed by flap-associated problems and migration (9 of 73 RCIs each [12.3%]). Flap retention problem appeared as a new cause in three cases (two CI 632 and one SYNCHRONY 2), and six electrode tip fold-over occurred (four CI 600 series and two CI 500 series). The 10-year overall cumulative and device survival rates were 93.4% and 95.8%, respectively. After excluding the models with recall issues, cumulative (P= 0.010) and device survival curves ( P= 0.001) revealed significant differences by manufacturer.

With rapid innovation in and expanding indications for cochlear implantation (CI), changes in the features of revision CI (RCI) appear to be emerging. This study aims to investigate the changes in RCI profile and discuss their clinical significance. Methods. A retrospective chart review was performed for all CIs performed at a tertiary medical institution between October 2001 and January 2023. The rate and reasons for RCI were evaluated and examined in terms of the manufacturer and device model. The Kaplan-Meier curve was used to examine the cumulative and device survival curves. In addition, the cumulative and device survivals were further analyzed based on age group, time period of primary CI, and manufacturer. Cox proportional hazards model was used to evaluate the association between RCI and manufacturers. Results. Among 1,430 CIs, 73 RCIs were conducted (5.1%). Device failure was the most common cause of RCI (40 of 73 RCIs [54.8%]), with an overall device failure rate of 2.8%, followed by flap-associated problems and migration (9 of 73 RCIs each [12.3%]).

Objective: This study aimed to compare the oncological outcomes of partial and superficial or total parotidectomies for superficial T1 or T2 primary parotid cancers and investigate their prognostic factors and recurrence patterns. Methods: The medical records of 77 patients with T1–2 primary parotid malignancies between May 2003 and March 2022 were retrospectively reviewed. Univariate and multivariate analyses were performed to evaluate the prognostic factors associated with overall survival, disease-free survival, and local and distant recurrences. Results: The average follow-up duration was 70.2 months (range,12–202 months). The 5-year overall and disease-free survival rates were 88.7% and 77.1%, respectively. Twenty-two patients underwent partial parotidectomy, and 55 underwent superficial or total parotidectomy. There were no significant differences in the disease recurrence ( p =0.320) and mortality rates ( p =0.884) of the partial and superficial or total parotidectomy groups. The mean duration of surgery was shorter and the overall complication rates were significantly lower for the partial group than for the superficial or total parotidectomy group ( p =0.049). Sixteen cases of recurrence occurred during the study period (20.8%). Univariate analyses showed that high-grade tumors ( p =0.006), lymphovascular invasion ( p =0.046), and regional lymph node metastasis ( p =0.010) were significant risk factors for disease recurrence. Multivariate analysis identified regional lymph node metastasis as an independent prognostic factor for disease recurrence ( p =0.027), and lymphovascular invasion as an independent prognostic factor for overall survival ( p =0.033). Conclusions: The conservative surgical approach of partial parotidectomy can yield oncologic outcomes comparable to superficial or total parotidectomies under careful patient
