​In der Abteilung Phoniatrie und Klinische Logopädie arbeitet ein interdisziplinäres Team aus Fachärzten für Phoniatrie und Otorhinolaryngologie und Klinischen Logopädinnen an verbesserten Möglichkeiten zur Diagnostik und Behandlung von Patienten mit Schluck- und Stimmstörungen. Die Arbeitsgruppe pflegt intensiven Austausch mit anderen nationalen und internationalen Forschergruppen und betreut akademische Qualifikationsarbeiten in der Medizin, Logopädie, Patholinguistik, Physiotherapie und biomedizinischen Wissenschaften.

Schwerpunkte in der angewandten Forschung sind die Erprobung und Validierung symptomspezifischer Fragebögen und die Untersuchung von Behandlungseffekten bei Patienten mit Schluck- und Stimmstörungen. Die Grundlagenforschung umfasst Projekte zur Optimierung von computergestützten instrumentellen akustischen Analysen der menschlichen Stimme in der klinischen Diagnostik von Stimmerkrankungen.

Projekt 1

Correlation of the Neck Disability Index (NDI) and Voice Handicap Index (VHI) in neck pain patients and patients with voice disorders

Anke Langenfeld, J. Swanenburg, J. Bohlender, M. Brockmann-Bauser

Neck pain is known as one of the risk factors for the development of voice disorders. In turn pain in the back of the cervical region and the shoulder girdle may be caused by inappropriate vocal behavior, finally leading to an increased muscle tension and muscle tension dysphonia. Main aim of the present cross-sectional study is to investigate if there is a correlation between neck related subjective symptoms and voice disorder related subjective symptoms in patients diagnosed with voice disorders.

Projekt 2

Characteristics of dysphagia and dysphonia in patients with unilateral vocal fold paralysis: a retrospective analysis

R. Hangartner, S. Reetz, J. Bohlender, M. Brockmann-Bauser

Unilateral vocal fold paralysis (UVFP) is a common disease encountered in ear, nose and throat specialized clinics. In spite of the absence of epidemiological studies addressing UVFP, calculation of the incidence of unilateral vocal fold mobility impairment in England finds 5.13 new cases per 100’000 per year. UVFP results mainly in voice dysfunction determined and assessed by visual laryngeal examination by videolaryngostroboscopy, objective acoustic voice measurements such as jitter and voice range profiles (VRP), perceptual voice sound assessments such as by Grading-Roughness-Breathiness-Asthenia-Strain-Scale and standardized examinations of subjective voice symptoms. Although it is a widespread opinion that UVFP is associated with dysphagia and a higher risk of aspiration, this has only been substantiated by a few previous studies. In addition, standardized questionnaires to characterize subjective dysphagia symptoms have been rarely used. Main aim of this study is to assess the incidence and the type of dysphagia in UVFP patients and its correlation with acoustic, perceptual and subjective voice dysfunction.

Projekt 3

Transcultural translation and validation of the german Vocal Fatigue Index (VFI)

L. Stappenbeck, J. Bohlender, M. Brockmann-Bauser

Vocal fatigue has been described as a common complaint in patients with voice disorders. However to date there is no standardized questionnaire in german language to assess specific symptoms. Main aim of this prospective study is to assess the validity and retest reliability of the first german version of the Vocal Fatigue Index (VFI), an english questionnaire developed for voice patients to assess potential symptoms of vocal fatigue.

Projekt 4

Effect of Vocal Intensity on Cepstral Peak Prominence and Spectral Slope in Women with and without Voice Disorders

M. Brockmann-Bauser, J. Bohlender, R. Hillman, J. H. Van Stan, D. Mehta

Spectrum based instrumental acoustic voice measures such as smoothed cepstral peak prominence (CPPS) and spectral slope have been associated with laryngeal pathology and perceptual voice quality in voice patients. Recent work has shown that the spectral measure of Harmonics-to-Noise-Ratio (HNR) increases with elevated voice sound pressure level (SPL) in healthy speakers and individuals with voice disorders. It is unclear if similar SPL effects are present in cepstral and other spectral measures. Therefore, main aim of the present study is to investigate SPL effects on CPPS and spectral slope in women with and without voice disorders.
