Dysphonia in the aging: physiology versus disease.

A chart review from 151 dysphonic patients over the age of 60 was done to define aging related voice disorders. Overwhelmingly, patients suffered from dysphonia due to disease processes associated with aging rather than to physiologic aging alone. These include: 1. central neurological disorders affecting laryngeal function (e.g., stroke, Parkinson's disease, essential tremor, Alzheimer's disease); 2. benign vocal fold lesions (e.g., Reinke's edema, benign and dysplastic epithelial lesions); 3. inflammatory disorders (e.g., laryngitis sicca, medication effect); 4. laryngeal neoplasia; and 5. laryngeal paralysis. Typical laryngeal findings of vocal fold bowing and breathiness consistent with presbylarynges were present in only six patients. Presbylarynges is not a common disorder and should be a diagnosis of exclusion made only after careful medical and speech evaluation.     

Presbyvertigo-aging of otoconia and vestibular sensory cells

Imbalance is a common clinical problem in elderly persons. Subsequently falls and fractures may occur. Age-related balance problems constitute an underestimated but prominent public health problem and a socioeconomic burden. At the histological level the peripheral vestibular system in animals and humans exhibits a variety of age-related changes. The number of otoconia in the utricule and the saccule is reduced with increasing age. Degenerated otoconia caused by aging showed distinct changes of the shape. Moreover age-related decreasing hair cell counts, lipofuscin inclusions and deformation of cilia are observed in human vestibular sensory and supporting cells. Results of vestibular function testing of age-related balance disorders still remain controversially. Regular balance training and vestibular rehabilitation results in less more falls and imbalance.     

The effect of age on vestibular rehabilitation outcomes

OBJECTIVE: The purpose of the retrospective chart review was to compare vestibular rehabilitation outcomes in young versus older adults. STUDY DESIGN: Retrospective matched design. METHODS: Twenty-three persons with vestibular disorders aged 20 to 40 years were matched by gender, vestibular diagnosis, and vestibular function test results to 23 older adults aged 60 to 80 years. The patients were treated with a custom-designed physical therapy exercise program. Patients completed the Dizziness Handicap Inventory, the Activities-Specific Balance Confidence (ABC) scale, and the Dynamic Gait Index; number of falls; and rated the severity of their dizziness. The two-sample test, the Mann-Whitney test, and McNemar's test for correlated proportions were used to determine whether there was a difference in scores between the two age groups at the beginning and end of physical therapy. RESULTS: During the initial evaluation, older adults reported having statistically greater space and motion discomfort and more severe symptoms on a scale of 0 to 100. Younger adults had more impaired DGI scores and a higher proportion of caloric testing abnormalities. After rehabilitation, overall improvement was seen in both the younger and older populations. There were no statistical differences between the two groups on the DHI, the DGI, reported symptoms at discharge, or number of falls. When only the complete matched-pair data were analyzed, there were no statistically significant differences between the age groups in the proportion of patients demonstrating clinical improvement. CONCLUSION: Age does not significantly influence the beneficial effects of vestibular rehabilitation for persons with vestibular disorders.     

Detection, evaluation, and management of aspiration in rehabilitation hospitals: role of the otolaryngologist--head and neck surgeon.

CONTEXT: Reductions in the length of acute care hospitalizations have resulted in earlier transfer of patients with significant neurologic disease, such as head injury or stroke, to inpatient rehabilitation facilities. In many instances, these patients arrive at the rehabilitation hospital with multiple unresolved acute processes, including undetected or inadequately evaluated dysphagia. These patients may be at significant risk for the development of aspiration pneumonia, especially if elderly or debilitated. OBJECTIVE: To review the role of otolaryngologic consultation in the management of inpatients in two rehabilitation hospitals. DESIGN AND SETTING: Retrospective review of 1046 consultations performed by two otolaryngologists over a 4-year period at two long-term inpatient rehabilitation hospitals in the Pittsburgh, PA, metropolitan area. RESULTS: A total of 833 patients were evaluated. Three hundred were seen for a variety of common disease processes, including hearing loss, and cerumen removal. A total of 548 consultations were for recommendations regarding swallowing dysfunction. Fibre-optic endoscopic examination of swallowing function was performed in 478 patients. Two hundred consultations were for assistance in decannulation of patients who were transferred from the acute care hospital with an indwelling tracheostomy tube. CONCLUSIONS: The detection and evaluation of the aspiration risk of dysphagic patients in rehabilitation hospitals are enhanced by an onsite dysphagia team with access to instrumented measures of swallowing, especially videofluoroscopy or videoendoscopy. Otolaryngologic consultation can provide considerable benefit for many inpatients in rehabilitation hospitals, even those with apparent "minor" dysfunction. The otolaryngologist-head and neck surgeon is uniquely qualified to provide consultation in the management of those inpatients with complex clinical problems involving the upper aerodigestive tract. Consultation may be critical for some patients, assessing the cause and severity of dysphagia and assisting in the safe decannulation of those with indwelling tracheostomy tubes.

Physician hearing loss

PURPOSE: Hearing is an important sense for physicians, making communication and stethoscope use possible, yet not much is known about the impact of hearing loss on professional function. The purpose of this study was to explore hearing-related issues affecting physicians. MATERIALS AND METHODS: We administered a hearing test and questionnaire to 107 physicians and medical students. RESULTS: The proportion of physicians reporting trouble with their hearing increased with age, reaching almost 100% in those older than 60 years. Audiometric hearing loss also increased with age. Perceived hearing trouble was significantly associated with audiometric hearing loss, yet 46% of physicians with hearing loss described their hearing as good. Older physicians more frequently reported difficulty communicating with patients, staff, and colleagues owing to hearing problems (P = .007). Reported stethoscope difficulties did not significantly increase with age; there was no association with hearing thresholds. No physician reported use of electronic stethoscopes or hearing aids. Noise exposures were common, yet 51% of respondents never used hearing protection. Younger physicians were less likely to use protection (P = .002). CONCLUSION: Physicians lose hearing with age but may not notice or report the loss. Physician hearing loss is associated with difficulty communicating with patients, staff, and colleagues. Neither age nor hearing level predicts problems with stethoscope use; possible explanations include a training effect or denial. Many physicians, especially younger ones, never use hearing protection around noise. Strategies to recognize and reduce the impact of hearing loss on professional function throughout a physician's career deserve greater attention.     

The rehabilitation of the tongue in hypoglossal-facial anastomosis

End to end hypoglossal-facial nerve anastomosis (tt HFA) is a traditional technique for rehabilitation of facial palsy. The sacrifice of the hypoglossal nerve generates a paralysis and an atrophy of the tongue which is thought to lead to speech, chewing and swallowing disorders. In a previous study, we demonstrated that tt HFA does not lead to speech disorders (Gatignol et al 2003). OBJECTIVES: In this work, we were interested in the functional consequences of the lingual atrophy and in the possibilities of rehabilitation with early therapy. MATERIAL AND METHODS: Nine patients were distributed in two groups, in one patients received a specific and early lingual rehabilitation in the other no specific treatment. These two groups (paired with control subjects) were subjected to a series of tests studying the motor function, the articulation (using palatograms). RESULTS: This study highlights the interest of early rehabilitation of the tongue in the first post-operative days. Early rehabilitation was associated with a reduction in lingual atrophy, an improvement in motility of the tongue thus generating a better management of saliva and stagnant food in the oral vestibule on the paralysed side.     

Vestibular rehabilitation strategies and factors that affect the outcome

Ever since the introduction of Cawthorne–Cooksey exercises, vestibular rehabilitation (VR) has been gaining popularity in the treatment of the dizzy patient. Numerous studies support the effectiveness of VR in improving balance/walking skills, eye–head coordination and the quality of life of the patient. Different rehabilitation protocols have been used to treat patients with peripheral and central vestibular disorders. Assessment of the patients’ progress is based on the patients’ selfperception of dizziness and their functional skills. Factors such as age, medication, time of onset of vertigo and home based VR have been evaluated on their effect on the rehabilitation’s outcome. The aim of this review is to evaluate rehabilitation strategies and discuss the factors that affect the outcome.     

中耳肌肉生理及病理

中耳肌肉是耳部“降噪系统”中最为关键的部分,其在持续监测声学输入和动态调节听觉灵敏度方面发挥着重要的保护作用。当中耳肌肉收缩时, 它们将镫骨推入卵圆窗, 并增加内耳膜迷路内液体的压力。如果中耳肌肉失去调节内耳压力的能力, 如强直、痉挛或肌张力障碍, 产生的异常压力将对内耳压力产生影响, 并导致许多问题, 如耳鸣、梅尼埃病和感音神经性听力损失等。综述中耳肌肉的生理构造及各自所起的作用,讨论中耳肌肉功能紊乱与耳部疾病的联系。     

Vestibular functions in patients with idiopathic sudden sensorineural hearing loss and its relation to prognosis

ObjectiveBecause of the anatomically close relationship between the cochlea and the vestibular organs, cochlear function disorders may be accompanied by vestibular disorders. This study aimed to evaluate vestibular functions in patients with idiopathic sudden sensorineural hearing loss using VEMP, caloric test, and VNG test battery and its relation to prognosis.Materials and MethodsFor this study, 42 patients aged 18–55 years with idiopathic sudden sensorineural hearing loss and 30 volunteers who had no hearing and balance problems were included. Audiometry, cVEMP, oVEMP, caloric tests, and VNG tests were performed. Moreover, the effects of age, sex, time of admission, degree and configuration of hearing loss, accompanying vertigo, tinnitus, and ear fullness on improvement in hearing were evaluated.ResultsOf the 42 patients in the study group, 26 (56.52%) were male, 20 (43.48%) were female, and the mean age was 41.54 ± 12.23 years. Of the 30 individuals in the control group, 19 (63.3%) were male, 11 (36.7%) were female, and the mean age was 39.53 ± 13.03 years. There was no significant difference in the incidence of sudden sensorineural hearing loss in terms of sex and age, and the prognosis was better for female patients. Early admission to treatment was a factor of good prognosis; profound hearing loss, bilateral hearing loss and vertigo were factors of poor prognosis. Prognosis was better in patients with rising type audiogram configuration, while the prognosis was worse in patients with flat, descending and total hearing loss. Tinnitus and ear fullness had no effect on the prognosis. No anomalies were observed in VNG findings. Moreover, abnormal caloric response was higher in patients with profound hearing loss and total hearing configuration. Shortening was observed in cVEMP / oVEMP P1 and N1 latency after treatment. Furthermore, there was an improvement in abnormal responses after treatment.ConclusionIn this study, vestibular function was affected in patients with idiopathic sudden sensorineural hearing loss. The present study can help the development of a clinical strategy in the evaluation of the vestibular system in idiopathic SSNHL, patient follow-up, patient information, and the implementation of vestibular rehabilitation. Note that additional studies involving larger patients series are required.     

Peripheral vestibular system: Age-related vestibular loss and associated deficits

Given the interdependence of multiple factors in age-related vestibular loss (e.g., balance, vision, cognition), it is important to examine the individual contributions of these factors with ARVL. While the relationship between the vestibular and visual systems has been well studied (Bronstein et al., 2015), little is known about the association of the peripheral vestibular system with neurodegenerative disorders (Cronin et al., 2017). Further, emerging research developments implicate the vestibular system as an opportunity for examining brain function beyond balance, and into other areas, such as cognition and psychological functioning. Additionally, the bidirectional impact of psychological functioning is understudied in ARVL. Recognition of ARVL as part of a multifaceted aging process will help guide the development of integrated interventions for patients who remain at risk for decline. In this review, we will discuss a wide variety of characteristics of the peripheral vestibular system and ARVL, how it relates to neurodegenerative diseases, and correlations between ARVL and balance, vision, cognitive, and psychological dysfunction. We also discuss clinical implications as well as future directions for research, with an emphasis on improving care for patients with ARVL.

目的：了解阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者的扩展高频纯音听阚情况。方法：对青年组、成年组和OSAHS组进行常频和扩展高频听阈及扩展高频各频率的检出率测试,并对检查结果进行方差分析和χ^2检验。结果：青年组在4、6和8kHz处的听阙略高（P〈0．05）;成年组随着年龄的增长,听阚值有逐渐提高的趋势（P〈0．05）。高频听阚测试显示青年组的听阚随频率的增高而增高（P〈0．05）,同时对于各个频率,随年龄的增长听阈也逐渐增高（P〈0．05）。OSAHS组各小组在常频段就已经出现了听阈提高,且随着年龄的增长提高更明显（P〈0．05）,同年龄组中OSAHS组的高频听阚较成年组明显增高（P〈0．05）,检出率明显下降（P〈0．05）。结论：OSAHS患者的常频和高频听阚均比正常同年人高,以此给OSAHS监测工作提供参考。     

Presbiacusia y trastornos del equilibrio en personas mayores. Revision bibliográfica de aspectos etiopatogénicos,consecuencias sobre la calidad de vida y efectos positivos de su tratamiento

At this time, we still do not have adequate knowledge and awareness of the consequences of hearing loss in the elderly on quality of life. Similarly, there is also insufficient information on the relationship of presbycusis and balance disorders with other comorbidities. Such knowledge can contribute to improve both prevention and treatment of these pathologies, to reduce their impact on other areas such as cognition or autonomy, as well as to have more accurate information on the economic impact they generate in society and in the health system.Therefore, with this review article we aim to update the information on the type of hearing loss and balance disorders in people over 55 years of age, and their associated factors; to analyze the impact on the quality of life of these people and the one which can be generated at a personal and population level (both sociological and economic) if an early intervention in these patients is pursued.     

Acquired bilateral peripheral vestibular system impairment: rehabilitative options and potential outcomes

Acquired bilateral vestibular impairment can be a devastating disorder that is most frequently the result of aminoglycoside-induced toxicity. The presenting complaints are typically oscillopsia and gait and balance disturbances. These patients can be excellent candidates for vestibular rehabilitation therapy that focuses on facilitating maximal use of any remaining vestibular function, improving gaze and postural stability through the use of visual and somatosensory cues, and improving home and workplace safety. The prognosis for recovery is determined by the extent of the loss and the presence of other progressive disorders that may affect vision or somatosensation, coexisting illnesses, and the patient's compliance with the therapy program. Two cases are presented to illustrate the salient aspects of vestibular rehabilitation for patients with acquired bilateral vestibular system loss, including factors affecting patient progress and final outcome.     

Effects of age and age-related hearing loss on the brain

It is well documented that aging adversely affects the ability to perceive time-varying acoustic cues. Here we review how physiological measures are being used to explore the effects of aging (and concomitant hearing loss) on the neural representation of temporal cues. Also addressed are the implications of current research findings on the rehabilitation of older hearing-impaired adults. LEARNER OUTCOMES: (1) Identify one evoked potential that reflects age-related physiological changes in the brain. (2) List three contributing factors for why older adults have difficult understanding speech in noise. (3) Give an example of a top-down approach to auditory rehabilitation.     

Vestibular hair cell regeneration and restoration of balance function induced by math1 gene transfer.

HYPOTHESIS: Delivery of math1 using an adenovector (Admath1.11D) results in vestibular hair cell regeneration and recovery of balance function in ototoxin-treated adult mice. BACKGROUND: Loss of peripheral vestibular function is associated with disease processes such as vestibular neuronitis, aminoglycoside ototoxicity, and aging. Loss of vestibular hair cells is one of the mechanisms underlying balance dysfunction in all of these disorders. Currently, recovery from these diseases relies on central vestibular compensation rather than on local tissue recovery. Overexpression of the mammalian atonal homologue math1 has been demonstrated to induce generation of hair cells in neonatal organ of Corti cultures and in the guinea pig cochlea in vivo and could thus provide an approach to local tissue recovery. METHODS: Admath1.11D was applied to cultures of aminoglycoside-treated macular organs or in vivo in a mouse aminoglycoside ototoxicity model. Outcome measures included histologic examination, immunohistochemistry, swim testing, and evaluation of the horizontal vestibulo-ocular reflex. RESULTS: Delivery of math1 resulted in the generation of vestibular hair cells in vitro after aminoglycoside-mediated loss of hair cells. Math1-treated mice showed recovery of the vestibular neuroepithelium within 8 weeks after Admath1.11D treatment. Assessment of animals after vector infusion demonstrated a recovery of vestibular function compared with aminoglycoside-only-treated mice. CONCLUSION: Molecular replacement of math1 may provide a therapeutic means of restoring vestibular function related to vestibular hair cell loss.     

Positive experiences associated with acquired hearing loss,Ménière's disease,and tinnitus: A review

Objective: It is common to study and understand how various illness and disorders result in negative consequences. However, positive experiences have been reported in a range of disabling conditions including multiple sclerosis, heart disease, physical and sensory disabilities. This paper presents a literature review of studies that have explored positive experiences associated with acquired hearing loss, Ménière's disease, and tinnitus. Design: A review of the peer reviewed scientific literature. Study sample: A comprehensive search strategy identified 15 articles after applying inclusion criteria. Results: A range of positive experiences have been reported by patients with hearing and balance disorders and by their significant others. Associations between demographic variables (e.g. age, gender), audiological variables (e.g. severity of the condition, duration) and the reported positive experiences are low. In Ménière's disease, self-reported positive experiences can predict the impact of the condition. However, this phenomenon has not yet been demonstrated in relation to hearing loss and tinnitus. Conclusions: Positive experiences associated with audio-vestibular disorders have been demonstrated. Further research is needed on the long-term benefits of the encouragement of such experiences and positive attitudes in persons with hearing loss, tinnitus, and imbalance.     

The five times sit to stand test: responsiveness to change and concurrent validity in adults undergoing vestibular rehabilitation

OBJECTIVE: The purpose of this study was to determine if patients with balance and vestibular disorders would demonstrate clinically meaningful improvement in the Five Times Sit to Stand Test (FTSST) score as a result of vestibular rehabilitation and to determine the concurrent validity of the FTSST. DESIGN: Retrospective chart review of 351 people who underwent individualized outpatient vestibular rehabilitation programs. SETTING: Outpatient tertiary balance and vestibular clinic. SUBJECTS: One hundred and seventeen patients (45 men, 72 women), mean age 62.7 years, with peripheral, central or mixed vestibular dysfunction. MAIN OUTCOME MEASURES: FTSST, gait speed, Timed Up and Go Test (TUG), Dynamic Gait Index (DGI), Dizziness Handicap Inventory (DHI), and Activities-Specific Balance Confidence Scale (ABC). RESULTS: The mean change in FTSST score was 2.7 seconds. Subjects demonstrated statistically significant improvements in the FTSST, gait speed, ABC, DHI, DGI and TUG after vestibular rehabilitation (p < 0.01). The responsiveness-treatment coefficient (RT) was calculated as 0.58 for the FTSST indicating moderate responsiveness. Logistic regression showed that an improvement in the FTSST of greater than 2.3 seconds resulted in an odds ratio of 4.67 for demonstrating clinical improvement in DHI, compared with a change less than 2.3 seconds. The univariate linear regression model for baseline FTSST predicting FTSST change was significant (p < 0.01) and predicted 49% of the change variance. The FTSST scores demonstrated a moderate correlation with gait speed and the TUG (p< 0.01). FTSST improvement subsequent to vestibular rehabilitation was moderately correlated with improvements in the DGI and the TUG scores (p< 0.01). CONCLUSIONS: The FTSST was moderately responsive to change over time and was moderately related to measures of gait and dynamic balance.     

Psychosocial adaptations to dual sensory loss in middle and late adulthood

Concurrent losses of hearing and vision function, or dual sensory loss, affect a large number of individuals of all ages and particularly older adults. Dual sensory loss may present at any age as a result of genetic defect, accident, injury, disease, or environmental insult; however, most persons develop this condition as a result of age-related disease processes that rarely result in total deafness or blindness. This condition has wide-ranging implications for physical and psychological functioning and quality of life. In this article, we review the prevalence and causes of dual impairment and its effects on functioning for both individuals affected and their families. We examine psychosocial coping and adaptation to this condition using biopsychosocial-spiritual and ecological models and discuss various strategies for coping and adaptation. The impact of larger societal forces on psychosocial adaptation is presented, followed by recommendations for how rehabilitation and other professionals can meet the challenge of dual sensory loss that awaits us with the aging of the population.
