The Relation Between Endoscopic and Subjective Laryngopharyngeal Reflux Signs, Vocal Tract Discomfort, Voice Handicap, and Voice Disorder Type: Same Yet Different?

OBJECTIVES: This study aimed to investigate the relation between subjective voice-related symptoms and endoscopic findings in patients with different etiology of voice disorder and vocally healthy subjects with and without laryngopharyngeal reflux (LPR). STUDY DESIGN: Retrospective cross-sectional study. METHODS: The study involved 149 participants (106 female, 43 male) including 125 with various voice disorders (functional, structural, and neurogenic) and 24 vocally healthy individuals. For self-rating the German versions of the Voice Handicap Index (VHI), Vocal Tract Discomfort (VTD) Scale, and Reflux Symptom Index (RSI) were applied, while endoscopic evaluations utilized the Reflux Finding Score (RFS) and Reflux Sign Assessment (RSA). Statistical analyses incorporated ANOVA with Bonferroni posthoc tests to identify group variations. Correlations between VTD Scale, VHI, RSI, RFS, and RSA were evaluated using Pearson's correlation coefficient. To examine test sensitivity and specificity for the VTD Scale and RSA, we performed a receiver operating characteristics analysis. Youden's-Index was applied to determine the cut-off-value with best discriminatory abilities. The diagnosis of LPR was assumed when the criteria of RFS > 7 AND RSI > 13 was met. RESULTS: Significant differences for all voice diagnosis groups and vocally healthy individuals for RFS and all three self-rating questionnaires were found. Moreover, there was significant correlation between VTD Scale and VHI and RSI as well as RSI and RFS, which was moderate, negative in the group of persons with LPR. However, there was no significant difference for RSA results between the vocally healthy or any diagnosis group. CONCLUSION: Thus, the RFS may be more suitable to predict reflux and voice-related symptoms. The VTD Scale is a useful instrument in screening voice disorders but also LPR and can therefore be used as a tool for decision-making when transferring to a specialist.

Do Not Go Gentle into That Deaf Night: A Holistic Perspective on Cochlear Implant Use as Part of Healthy Aging.

Research suggests that cochlear implant (CI) use in elderly people improves speech perception and health-related quality of life (HRQOL). CI provision could also prevent dementia and other comorbidities and support healthy aging. The aim of this study was (1) to prospectively investigate potential changes in HRQOL and speech perception and (2) to identify clinical action points to improve CI treatment. Participants (n = 45) were CI recipients aged 60-90 with postlingual deafness. They were divided into groups, according to age: Group 1 (n = 20) received a CI between the age of 60-70 years; group 2 (n = 25) between the age of 71-90 years. HRQOL and speech perception were assessed preoperatively, and three and twelve months postoperatively. HRQOL and speech perception increased significantly within one year postoperatively in both groups. No difference between groups was found. We conclude that CI treatment improves speech perception and HRQOL in elderly users. Improvement of the referral process for CI treatment and a holistic approach when discussing CI treatment in the elderly population could prevent auditory deprivation and the deterioration of cognitive abilities.

Subjective Voice Handicap and Vocal Tract Discomfort in Patients With Cochlear Implant.

OBJECTIVES: Changes in the auditory system, for example due to hearing impairment, can cause changes in breathing, phonation, and articulation. Aim of this study was to provide first data on subjective Voice Handicap and Vocal Tract Discomfort in subjects with hearing impairment and cochlear implant (CI) after initial fitting. STUDY DESIGN: Prospective cross-sectional study METHODS: A total of 111 participants (57 female and 54 male) between 20 and 85 years of age (mean = 58.21, SD = 14.96) were recruited between October 2019 and March 2020 from the Clinic of Otorhinolaryngology at Medical University of Hannover. Participants were tested after initial CI fitting, six weeks after implantation, using the German version of the VTD (Vocal Tract Discomfort) Scale and VHI (9i) (Voice Handicap Index) as well as speech comprehension tests and a specifically developed questionnaire evaluating data concerning voice usage and other influential factors. Statistics included descriptive analysis, group comparisons (t-Test), Pearson correlation coefficient between VTD Scale and VHI, and hearing status. RESULTS: Patients with CI did show low scores in VTD Scale and VHI-9i (VTD mean = 7.85 [SD = 10.4]; VHI-9i mean = 4.04 [SD = 5.77]). We found neither a correlation between any of the speech comprehension tests and the VTD Scale nor the VHI-9i. Further, we could show no correlation between subjective Voice Handicap and/or Vocal Tract Discomfort and age or the kind of treatment. CONCLUSION: Patients included in this study did not show more subjective Voice Handicap or Vocal Tract Discomfort than normal hearing peers. Scores of VTD Scale and VHI-9i did not depend on the duration of hearing loss, speech comprehension, kind of treatment or age.

Can Cochlear Implantation in Older Adults Reverse Cognitive Decline Due to Hearing Loss?

INTRODUCTION: Older adults with late-onset hearing loss are at risk for cognitive decline. Our study addresses the question of whether cochlear implantation (CI) can counteract this potential influence. We investigated whether cognitive performance in older adults with severe and profound hearing loss improves 12 months after CI to a level comparable to controls with normal hearing, matched for age, sex, and education level. DESIGN: This cohort study was performed at two tertiary referral centers. The study included 29 patients, of age between 60 and 80 years, with adult-onset, severe to profound bilateral sensorineural hearing loss and indication for CI (study group), as well as 29 volunteers with age-adjusted hearing abilities, according to the norm curves of ISO-702 9:2000-01, (control group). Before CI and 12 months after CI, participants completed a neurocognitive test battery including tests of global cognition, verbal and figural episodic memory, and executive functions (attentional control, inhibition, and cognitive flexibility). RESULTS: Twelve months after CI, the performance of the study group improved significantly in global cognition, compared to the situation before CI. Differences in verbal episodic memory, figural episodic memory, and executive function were not significant. Moreover, the improvement of the study group was significantly larger only in global cognition compared to the control group. Noninferiority tests on the cognitive performances of the study group after CI revealed that comparable levels to normal hearing controls were reached only in global cognition, figural episodic memory (immediate recall), and attentional control. The improvement in global cognition was significantly associated with speech recognition 3 months after CI, but not with speech recognition 12 months after CI. CONCLUSION: One year after CI, cognitive deficits in older individuals with adult-onset hearing loss, compared to normal-hearing peers, could only improve some cognitive skills.

Cross-Validation and Normative Values for the German Vocal Tract Discomfort Scale.

Purpose The Vocal Tract Discomfort Scale (VTD Scale) is a self-rating questionnaire investigating physical symptoms in the larynx associated with vocal pathology. The aim of this work was to investigate the reliability, validity, sensitivity, and specificity of the first German version and to provide normative data with thresholds for pathology and a scaling scheme. Study Design A retrospective multicenter study was performed. Method A total of 571 participants (409 female and 162 male), with a mean age of 47.2 years, were recruited at three German centers; of these, there were 447 participants with voice disorder and 124 vocally healthy participants. The clinical examination consisted of patient history, visual laryngeal examination, acoustic and aerodynamic assessment, perceptual analysis by the Grading-Roughness-Breathiness-Asthenia-Strain Scale, and subjective evaluation using the VTD Scale and the Voice Handicap Index (VHI). Statistics included group comparisons (t test and analysis of variance), Pearson correlation coefficient (between VTD Scale and VHI), and Cronbach's alpha to assess validity and reliability. Analysis of receiver operating characteristics was performed to examine VTD Scale's discriminatory ability and provide a cutoff score. Additionally, percentiles were applied to provide VTD Scale ranges. Results There were highly significant differences between healthy participants and participants with voice disorder regarding the total score and both subscales of the VTD Scale. Internal consistency was excellent (α = .928). We found moderate, positive correlation between the VTD Scale and VHI (ρ = .596, p < .001). Receiver operating characteristics analysis showed an area under the curve of 0.876 (p < .001, 95% confidence interval [0.846, 0.906]). VTD Scale ranges were no (score: 0-13), mild (score: 14-26), moderate (score: 27-40), and severe (score: 41-96) disorder. Conclusions Results confirm an excellent reliability and validity of the German VTD Scale. It provides additional and independent diagnostic information and is a useful instrument to complement voice assessment. The scaling into four severity subgroups allows the tool to be used for screening patients and considers a transferral to a voice specialist.

Cognition in older adults with severe to profound sensorineural hearing loss compared to peers with normal hearing for age.

Objective: Cognitive performance of older adults with severe to profound sensorineural hearing loss and indication for cochlear implantation was evaluated compared to peers with age appropriate hearing.Design: Prospective matched case control study.Study sample: Study group consisted of n = 30 patients aged between 60 and 80 years, with adult onset, severe to profound sensorineural hearing loss on both sides and indication for cochlear implantation. Matched control group consisted of n = 30 peers with age-adjusted hearing abilities, based on age- appropriate norms.Results: Differences in Constructional Praxis and Recall, Trail Making Test A and Stroop were not significant between both groups. However, the differences in Clock Drawing Test, Word Lists and Trail Making Test B were significant. The impairment in TMT B (cognitive flexibility) was mediated via the severity of depressive problems. Cognitive performance was not related to word recognition, the percentage and duration of hearing loss and hearing aid use.Conclusion: Severely hearing-impaired older adults show widespread impairments in cognitive performance.

Transcultural Adaptation and Validation of the German Version of the Vocal Tract Discomfort Scale.

OBJECTIVES: Currently, there is no standardized German questionnaire to assess vocal tract discomfort in voice patients. The aim of this study was to evaluate the internal consistency, reliability, and validity of the German version of the Vocal Tract Discomfort (VTD) Scale. STUDY DESIGN: This is a cross-sectional study. METHODS: First, a cross-cultural translation and adaptation from English to German was performed. One hundred seven patients between the ages of 18 and 76 with voice disorders were divided into two different diagnosis-related groups (organic and functional voice disorder) and 50 vocally healthy adults were included. All participants completed the VTD Scale and the Voice Handicap Index (VHI). The internal consistency of the VTD Scale was analyzed through Cronbach's α coefficient. Pearson correlation between the VDT Scale and VHI total scores was used to determine criterion validity. The VDT Scale score differences related to diagnosis groups were assessed with analysis of variance. RESULTS: Excellent internal consistency was found (α = 0.919, P < 0.05), and criterion validity was confirmed by a high correlation between the total VTD Scale and VHI (r = 0.674). There was a significant difference between the diagnosis groups' total VTD Scale score (F[4.135] = 15.114, P = 0.000). Furthermore, the vocally healthy adults had significantly lower values than the two diagnosis groups (x¯: 11.48, s = 8.340). CONCLUSIONS: The German version of the VTD Scale has an excellent internal consistency and reliability, and shows high clinical validity. Thus, it is a useful instrument in voice diagnostics.
