    UNASSIGNED: Older adults suffer from increased rates of dysphagia and dysphonia, both of which have a profound effect on quality of life and are often underdiagnosed. We sought to better understand the prevalence of these complaints and the potential utility of a patient-reported screening program in a geriatrics clinic.
    UNASSIGNED: Using an IRB-approved cross-sectional survey and retrospective cohort design, we recruited participants from a population of new patients seeking care at an academic geriatrics clinic. We used three validated questionnaires to assess self-reported dysphagia, dysphonia, and pill dysphagia: the Eating-Assessment Tool-10 (EAT-10), the Voice Handicap Index-10 (VHI-10), and the PILL-5. Patients who screened positive on any questionnaire were offered referral to a laryngologist for additional evaluation. Patients who screened positive on the PILL-5 were also offered referral to our geriatric pharmacist.
    UNASSIGNED: Among our 300 patients surveyed, the mean age was 76 (SD 8.46). A total of 82 (27.3%) patients screened positive (73 on EAT-10, 10 on PILL-5, 13 on VHI-10) and were offered referral, of which 36 accepted. These positive screening patients took more prescription medications (p = .024) and had a higher GDS score (p < .001) when compared to the patients who screened negative.
    UNASSIGNED: Many new patients seeking generalized care at our center screened positively for dysphagia and/or dysphonia on validated questionnaires. Geriatric patients may benefit from integrating screening for these disorders to identify the need of further evaluation. It is unknown if these survey tools are appropriate in a non-otolaryngology clinic.
    UNASSIGNED: III.

    目的:注射喉成形术(IL)已被广泛用作单侧声带麻痹(UVFP)的初始治疗选择。另外的(第二)IL被认为是由于注射材料的不充分注射或早期再吸收导致的初始IL的不满意结果的补救治疗。本研究旨在评估额外IL的疗效,区分“抢救”(4个月内)和“重复”注射(超过4个月),并分析成功结局的预后因素。
    方法:这项回顾性研究涉及2014年1月至2020年12月在Asan医疗中心接受IL治疗的患者。每次手术后采集语音参数,进行统计分析的人对研究对象不了解。在接受额外IL治疗的65例患者中,51名患者参加了这项研究。注射后等级,粗糙度,呼吸,虚弱,应变(GRBAS)量表用于确定满意的治疗结果。额外IL的成功定义为注射后发音障碍评分为0或1,与注射前评分相比,评分降低。
    结果:患者的平均年龄为61.6岁。在总共51名患者中,37名男性参与了这项研究。比值比表示在第二IL中成功的可能性。23例(45%)患者维持了额外的IL后语音结果的改善。与失败组相比,成功组的初始注射和额外注射之间的注射时间间隔较长(9.1vs.7.4个月,分别,p=0.010)。成功组注射间隔>6个月的患者比例更高(73.9%vs.42.9%,p=0.026)。Logistic回归分析显示,注射间隔>6个月的比值比为0.265(置信区间:0.080-0.874,p=0.029)。
    结论:在首次注射后,语音结果维持较长时间(>6个月)的患者,额外注射将受益。
    OBJECTIVE: Injection laryngoplasty (IL) has been widely used as an initial treatment option for unilateral vocal fold paralysis (UVFP). An additional (second) IL is considered a salvage treatment for unsatisfactory outcomes of initial IL resulting from inadequate injection or early resorption of the injection material. This study aims to evaluate the efficacy of additional IL, distinguishing between \"salvage\" (within 4 months) and \"repeated\" injections (beyond 4 months), and to analyze prognostic factors for successful outcomes.
    METHODS: This retrospective study involved patients who received IL at Asan Medical Center from January 2014 to December 2020. Voice parameters were collected after each procedure, and those who conducted the statistical analysis were blinded to the study subjects. Among the 65 patients who underwent additional IL, 51 patients were enrolled in this study. Postinjection grade, roughness, breathiness, asthenia, strain (GRBAS) scales were used to determine satisfactory treatment outcomes. Success of the additional IL was defined as a postinjection grade of dysphonia score of 0 or 1, with a reduction in grade compared with the preinjection grade.
    RESULTS: The mean age of the patients was 61.6 years. Out of a total of 51 patients, 37 were men participating in the study. The odds ratio represents the likelihood of success in the second IL. Improved voice outcome after the additional IL was maintained in 23 (45%) patients. Compared with the failure group, the success group had a longer injection time interval between the initial and additional injection (9.1 vs. 7.4 months, respectively, p = 0.010). The success group had a higher proportion of patients with injection intervals >6 months (73.9% vs. 42.9%, p = 0.026). Logistic regression analysis revealed an injection interval >6 months had an odds ratio of 0.265 (confidence interval: 0.080-0.874, p = 0.029).
    CONCLUSIONS: Additional injections would benefit the patients whose voice outcomes are maintained for a longer period (>6 months) after the first injection.

    背景:吞咽和发声之间的复杂关系,分享解剖学和生理学基础,强调了对综合治疗方法的临床需求。现有的干预措施通常孤立地处理这些功能,忽略它们相互关联的动态。
    目的:设计并验证将吞咽困难治疗技术(动作/锻炼)纳入语音康复的交叉治疗方案。该协议旨在利用吞咽和发声的共享生物力学组件,以同时改善患有潜在喉功能减退病理的患者的两种功能。
    方法:采用描述性研究设计,由三个阶段组成:以德国研讨会形式进行全面的文献综述和专家讨论,以概念化方案;吞咽动作/练习的详细分析和分类;以及由七名专家组成的小组通过结构化评估工具进行的内容验证。该过程综合了运动学习和运动生理学原理,保证了方案的临床适用性和理论连贯性。
    结果:开发的交叉治疗方案将四个核心吞咽治疗技术结合到语音治疗程序中。选定的吞咽治疗技术针对喉偏移和声带闭合,因为它们是吞咽和发声的关键组成部分。对于大多数项目,专家验证产生的内容有效性系数超过0.90,表明对协议相关性的高度共识,清晰度,和适用性。根据反馈进行了调整,增强协议的精确性和用户友好性。
    结论:我们提出了一个新的,基于证据的治疗方案语音和吞咽困难引起的喉功能减退病理。它的发展标志着朝着弥合吞咽和语音治疗之间的差距迈出了重要的一步。需要未来的实证研究来评估其在临床环境中的有效性。
    BACKGROUND: The intricate relationship between swallowing and phonation, sharing anatomical and physiological substrates, underscores a clinical demand for integrated therapeutic approaches. Existing interventions often address these functions in isolation, overlooking their interconnected dynamics.
    OBJECTIVE: To design and validate a cross-therapy protocol incorporating dysphagia therapy techniques (maneuvers/exercises) into voice rehabilitation. This protocol aims to exploit the shared biomechanical components of swallowing and phonation to improve both functions simultaneously in patients with underlying hypofunctional laryngeal pathology.
    METHODS: A descriptive research design was employed, consisting of three phases: a comprehensive literature review and expert discussions in a German seminar format to conceptualize the protocol; detailed analysis and categorization of swallowing maneuvers/exercises; and content validation by a panel of seven experts through a structured evaluation instrument. The process integrated motor learning and exercise physiology principles to ensure the protocol\'s clinical applicability and theoretical coherence.
    RESULTS: The developed cross-therapy protocol incorporates four core swallowing therapy techniques to voice therapy procedures. Selected swallowing therapy techniques target laryngeal excursion and vocal fold closure because they are critical components of swallowing and phonation. Expert validation yielded a Content Validity Coefficient exceeding 0.90 for most items, indicating high consensus on the protocol\'s relevance, clarity, and applicability. Adjustments were made based on feedback, enhancing the protocol\'s precision and user-friendliness.
    CONCLUSIONS: We present a novel, evidence-based therapy protocol for voice and swallowing difficulties resulting from hypofunctional laryngeal pathology. Its development marks a significant step toward bridging the gap between swallowing and voice therapy. Future empirical studies are needed to assess its effectiveness in clinical settings.

    目的:调查美国语言病理学家(SLPs)与患有语音障碍的成年客户在频率方面的当前评估实践,实用程序,以及对使用五个要素进行全面语音评估的信心,以及训练,进入仪器,以及使用已发布的量表。
    方法:一项在线调查分发给SLP,这些SLP目前将成人发声障碍作为其病例的一部分。将语音集中环境中的临床医生与在一般医疗环境中工作的医生进行了比较。
    结果:几乎所有86名参与者报告使用已发布的验证量表进行患者自我评估和听觉感知评分。大多数受访者都接受过听觉感知语音评估方面的培训,声学评估,还有视光镜,但少数人报告了空气动力学评估方面的培训。大多数SLP都可以使用声学设备,但少数人可以使用仪器进行频闪或空气动力学评估。听觉感知语音评估是最常用的程序,也是诊断实用性最高的程序。研究生培训和获得仪器与所有三种仪器评估方法的使用频率和信心均显着提高。在以语音为中心的环境中,SLP更有可能接受过视光镜检查的培训并进行或解释。以语音为重点的环境中的SLP也更有可能使用所有三种仪器技术的设备,并且报告对其使用的信心明显更高。两组对语音评估的不同组成部分的效用进行了相似的评估,并且在使用经过验证的患者问卷或听觉感知量表方面,两组之间没有显着差异。
    结论:我们调查中的大多数临床医生报告说,在进行跨环境的全面语音评估时,遵循实践指南,尽管培训和获得仪器的障碍。
    OBJECTIVE: To investigate the current assessment practices of speech-language pathologists (SLPs) in the United States working with adult clients with voice disorders with regard to the frequency, utility, and confidence in the use of five elements of a comprehensive voice evaluation, as well as training, access to instrumentation, and the use of published scales.
    METHODS: An online survey was distributed to SLPs who currently see adults with dysphonia as part of their caseload. Clinicians in a voice-focused setting were compared to those who worked in a general medical setting.
    RESULTS: Nearly all of the 86 participants reported using published validated scales for patient self-assessment and auditory-perceptual ratings. Most respondents had received training in auditory-perceptual voice assessment, acoustic assessment, and videostroboscopy, but a minority reported training in aerodynamic assessment. The majority of SLPs had access to acoustic equipment but a minority had access to the instrumentation for videostroboscopic or aerodynamic assessment. Auditory-perceptual voice evaluation was the procedure most commonly performed and most highly rated for diagnostic utility. Postgraduate training and access to instrumentation were associated with significantly higher frequency of use and confidence with all three instrumental assessment methods. SLPs in voice-focused settings were significantly more likely to have received training in videostroboscopy and perform or interpret it. SLPs in voice-focused settings were also significantly more likely to have access to equipment for all three instrumental techniques and reported significantly higher confidence in their use. Both groups rated the utility of the different components of a voice evaluation similarly and there were no significant differences between the groups in the use of validated patient questionnaires or auditory-perceptual scales.
    CONCLUSIONS: Most clinicians in our survey reported following practice guidelines when performing comprehensive voice evaluations across settings, despite barriers of training and access to instrumentation.

    目的:本研究旨在调查这些模型之一在嗓音病理学领域的作用,并比较其在区分感知的发声障碍水平方面的表现。
    方法:人口统计信息,声音自我评估,并向ChatGPT和PerplexityAI聊天机器人提交了与50名成人言语障碍门诊患者样本相关的声学测量结果,被询问感知到的发声障碍水平。
    结果:专家的听觉感知评估与ChatGPT和困惑AI聊天机器人之间的协议,由科恩的Kappa决定,无统计学意义(p=0.429)。ChatGPT和PerplexityAI聊天机器人的诊断之间也存在较低的正相关(rs=0.30,p=0.03)。
    结论:人工智能似乎不能在帮助语音护理团队确定发音障碍的感知水平方面发挥至关重要的作用。
    OBJECTIVE: This study aims to investigate the role of one of these models in the field of voice pathology and compare its performance in distinguishing the perceived dysphonia level.
    METHODS: Demographic information, voice self-assessments, and acoustic measurements related to a sample of 50 adult dysphonic outpatients were presented to ChatGPT and Perplexity AI chatbots, which were interrogated for the perceived dysphonia level.
    RESULTS: The agreement between the auditory-perceptual assessment by experts and ChatGPT and Perplexity AI chatbots, as determined by Cohen\'s Kappa, was not statistically significant (p = 0.429). There was also a low positive correlation (rs = 0.30, p = 0.03) between the diagnosis made by ChatGPT and Perplexity AI chatbots (rs = 0.30, p = 0.03).
    CONCLUSIONS: It seems that AI could not play a vital role in helping the voice care teams determine the perceptual level of dysphonia.

    背景:小儿喉气管狭窄通常需要开放气道重建。虽然这些手术建立了充分通气的气道,许多患者随后出现发音困难。许多研究报告了与声音有关的结果。
    目的:本研究旨在评估开放式气道重建后儿科患者的发音障碍,专注于声学参数,感知语音质量,和语音相关的生活质量。
    方法:在6个数据库中使用系统评价和荟萃分析(PRISMA)指南的首选报告项目进行全面搜索,确定了涉及接受开放式气道重建并报告术后声乐声学参数的儿科患者的文章。感知语音质量,与语音相关的生活质量,或声乐力学。文章进行了偏倚风险评估,和共同结局采用meta分析进行定性和定量综合.
    结果:在4089篇文章中,包括21个,涉及497名儿科患者。喉气管成形术是最常见的手术,其次是环气管切除术。语音共识听觉感知评估(CAPE-V)量表经常用于评估语音质量,平均得分为55.6[95%置信区间(CI):47.9-63.3]。使用儿科语音障碍指数(pVHI)和儿科语音相关生活质量调查测量语音相关生活质量,平均得分为35.6分(95%CI:21.4-49.7)和83.7分(95%CI:74.1-93.2),分别。基频为210.5(95%CI:174.6-246.3)。其他常见发现包括声门上发声,前连合钝化,后声门分离,和异常的声带活动。
    结论:在开放气道重建后出现发音困难的儿童患者表现出语音质量中度下降和语音相关生活质量下降。然而,研究方案和使用的结局衡量标准存在不一致.在气道重建过程中保持语音质量对于避免对生活质量的负面影响至关重要。
    BACKGROUND: Pediatric laryngotracheal stenosis often requires open airway reconstruction. While these surgeries establish an airway for adequate ventilation, many patients develop subsequent dysphonia. Numerous studies have reported outcomes related to voice.
    OBJECTIVE: This study aims to evaluate dysphonia in pediatric patients following open airway reconstruction, focusing on acoustic parameters, perceptual voice quality, and voice-related quality of life.
    METHODS: A comprehensive search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across 6 databases identified articles involving pediatric patients who underwent open airway reconstruction and reported postoperative vocal acoustic parameters, perceptual voice quality, voice-related quality of life, or vocal mechanics. Articles were assessed for bias risk, and common outcomes were synthesized qualitatively and quantitatively using meta-analyses.
    RESULTS: Among 4089 articles, 21 were included, involving 497 pediatric patients. Laryngotracheoplasty was the most common procedure followed by cricotracheal resection. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) scale was frequently used to assess voice quality, with a mean score of 55.6 [95% confidence intervals (CIs): 47.9-63.3]. Voice-related quality of life was measured using the pediatric Voice Handicap Index (pVHI) and Pediatric Voice-Related Quality of Life Survey, with mean scores of 35.6 (95% CI: 21.4-49.7) and 83.7 (95% CI: 74.1-93.2), respectively. The fundamental frequency was 210.5 (95% CI: 174.6-246.3). Other common findings included supraglottic phonation, anterior commissure blunting, posterior glottic diastasis, and abnormal vocal cord mobility.
    CONCLUSIONS: Pediatric patients experiencing dysphonia after open airway reconstruction exhibited moderately decreased voice quality and reduced voice-related quality of life. However, there was inconsistency in study protocols and outcome measures used. Preserving voice quality during airway reconstruction is crucial to avoid negative impacts on quality of life.

    目的:本研究旨在阐明小儿嗓音障碍的临床特征。
    方法:对1782例嗓音障碍患儿的临床资料进行回顾性分析。这些病例分为四个基于年龄的队列:0-3、4-7、8-11和12-15岁。性别差异等变量,喉镜表现,疾病类型,和声学参数进行了彻底检查。
    结果:本研究共纳入1782名声嘶哑儿童,包括1325名男性和457名女性。当比较各组儿童的性别比例时,发现男性数量超过女性。在所有年龄组中都观察到明显的男性优势。喉镜检查结果显示,最普遍的情况是声带结节(1363例,76.48%),其次是声带息肉(271例,15.20%)。其他疾病包括喉乳头状瘤,声带运动障碍,声带囊肿,功能性发声障碍,声带白斑,以及喉淀粉样变性和声门下颗粒细胞瘤等喉良性肿瘤。其中,382名儿童(21.44%)出现腺样体肥大。此外,进行了反流发现评分(RFS),799例(44.83%)得分在7分以上。各种疾病在不同年龄段的分布表明,儿童声带小结(637例,46.74%),声带息肉(109例,40.22%),喉乳头状瘤(35,36.84%)主要发生在4-7岁年龄段。小儿急性喉炎(3例,75%)和声带运动障碍(8例,36.36%)在0-3岁年龄组中更为常见。功能性发音障碍(4例,66.67%)和声带白斑(4例,80%)主要在12-15岁年龄段观察到,而声带囊肿主要见于8-11岁年龄组(4例,57.14%)。对153名儿童的声学参数进行比较分析,发现抖动差异有统计学意义,基频(F0),语音障碍指数(VHI),反流症状指数(RSI),和不同病理的RFS。
    结论:这项研究强调了声带小结,声带息肉,喉乳头状瘤是小儿声音嘶哑的主要原因,尽管不能忽视肿瘤和罕见疾病的可能性。对男性有明显的性别偏见,功能性发音障碍在年龄较大的儿童中更为普遍。
    OBJECTIVE: This study aims to clarify the clinical characteristics of pediatric voice disorders.
    METHODS: The clinical data of 1782 pediatric patients presenting with voice disorders were retrospectively analyzed. These cases were categorized into four age-based cohorts: 0-3, 4-7, 8-11, and 12-15years. Variables such as gender disparities, laryngoscopic manifestation, disease types, and acoustic parameters were thoroughly examined.
    RESULTS: A total of 1782 children with acoustic hoarseness were included in this study, comprising 1325 males and 457 females. When the sex ratio among the children in each group was compared, males were found to outnumber females. A notable male predominance was observed across all age groups. Laryngoscopic results revealed that the most prevalent condition was vocal cord nodules (1363 cases, 76.48%), followed by vocal cord polyps (271 cases, 15.20%). Other diseases included laryngeal papillomas, vocal fold movement impairment, vocal cord cysts, functional dysphonia, leukoplakia of the vocal cords, and benign laryngeal tumors such as laryngeal amyloidosis and subglottic granular cell tumors. Among these, adenoid hypertrophy was presented in 382 children (21.44%). Additionally, the Reflux Finding Score (RFS) was conducted, and 799 cases (44.83%) were found to have a score above 7. The distribution of various diseases across different age groups indicated that children with vocal cord nodules (637 cases, 46.74%), vocal cord polyps (109 cases, 40.22%), and laryngeal papillomas (35, 36.84%) were predominantly found in the 4-7 years age group. Pediatric acute laryngitis (three cases, 75%) and vocal fold movement impairment (eight cases, 36.36%) were more common in the 0-3 years age group. Functional dysphonia (four cases, 66.67%) and vocal cord leukoplakia (four cases, 80%) were mainly observed in the 12-15 years age group, while vocal cord cysts were predominantly seen in the 8-11 years age group (four cases, 57.14%). A comparative analysis of acoustic parameters among 153 children showed statistically significant differences in jitter, fundamental frequency (F0), voice handicap index (VHI), reflux symptom index (RSI), and RFS across different pathologies.
    CONCLUSIONS: This study highlighted that vocal cord nodules, vocal cord polyps, and laryngeal papillomas were the primary causes of pediatric hoarseness, although the possibility of tumors and rare diseases cannot be disregarded. There was a noticeable gender bias towards males, and functional dysphonia was significantly more prevalent in older children.

    许多语音障碍与不平衡的肌肉活动有关,并且已知表现出不对称的声带振动。然而,不平衡的肌肉激活和不对称的声带振动之间的关系尚不清楚。这项研究引入了声带的非对称三角形身体覆盖模型,由双侧喉部固有肌肉的激活控制,探讨肌肉失衡对声带振荡的影响。考虑了各种情况,包括个体肌肉和肌肉对的不平衡,以及考虑集总元件参数的不对称性。采用幅度和相位不对称性的测量来匹配两种病理情况的振荡行为:单侧瘫痪和肌肉张力发声障碍。由此产生的模拟显示肌肉失衡与这些声音障碍的组成预期一致,瘫痪产生的不对称超过30%,发声困难产生的不对称低于5%。这强调了肌肉失衡在表示发声情景中的相关性及其在表征声带振动中的不对称性方面的潜力。
    Many voice disorders are linked to imbalanced muscle activity and known to exhibit asymmetric vocal fold vibration. However, the relation between imbalanced muscle activation and asymmetric vocal fold vibration is not well understood. This study introduces an asymmetric triangular body-cover model of the vocal folds, controlled by the activation of bilateral intrinsic laryngeal muscles, to investigate the effects of muscle imbalance on vocal fold oscillation. Various scenarios were considered, encompassing imbalance in individual muscles and muscle pairs, as well as accounting for asymmetry in lumped element parameters. Measurements of amplitude and phase asymmetries were employed to match the oscillatory behavior of two pathological cases: unilateral paralysis and muscle tension dysphonia. The resulting simulations exhibit muscle imbalance consistent with expectations in the composition of these voice disorders, yielding asymmetries exceeding 30% for paralysis and below 5% for dysphonia. This underscores the relevance of muscle imbalance in representing phonatory scenarios and its potential for characterizing asymmetry in vocal fold vibration.

    单侧声带麻痹(UVFP)对患者的生活质量有已知的影响。尚未研究的潜在受影响的领域之一是情绪韵律。为了产生和传播有效的情感韵律,几个声音参数由说话者调制,主要是基频,语速,和声音强度。我们检索了10名患有UVFP的患者产生的300个句子,同样保持中立,愤怒,和悲伤。由六名医疗保健语音专家组成的陪审团被要求听到这些句子,并为每个发声选择一种情感,在中立之间,愤怒,和悲伤。陪审团主要认为听到的判决处于中立情绪。对被误认为中立的愤怒和悲伤句子的声乐参数分析表明,它们的基本频率和语速没有显着差异。由于无法根据需要调节他们的声音参数来产生情绪韵律,特别是基本频率和语速,患有UVFP的患者在产生所需的情绪韵律的能力方面受到限制,使他们感觉到的情绪很难传递给他们的随行人员,这可以解释这些患者抱怨的社会障碍。
    Unilateral vocal fold paralysis (UVFP) has a known impact on patients\' quality of life. One of the potentially affected domains that has not been studied yet is emotional prosody. To produce and transmit an efficient emotional prosody, several vocal parameters are modulated by the speaker, principally the fundamental frequency, the speech rate, and the voice intensity. We retrieved 300 sentences produced by 10 patients suffering from UVFP, equally in neutral, anger, and sadness. A jury of six health care voice experts was asked to hear these sentences and choose an emotion for each vocalization, between neutral, anger, and sadness. The jury mainly considered the heard sentences as being in a neutral emotion. Vocal parameters analysis of the anger and sadness sentences that were mistaken as neutral showed the absence of significant difference in their fundamental frequencies and speech rates. By being unable to modulate their vocal parameters as needed to produce emotional prosody, specifically the fundamental frequency and speech rate, patients with UVFP suffer from limitations in their capacity to produce the emotional prosody wanted, making the emotions they feel hardly transmitted to their entourage, which can explain the social barriers these patients complain of.
