Position Statement of the Union of European Phoniatricians (UEP): Fees and Phoniatricians' Role in Multidisciplinary and Multiprofessional Dysphagia Management Team.

The need for multidisciplinary and multiprofessional management of dysphagia is constantly increasing and creating a major challenge for healthcare professionals and society, especially in terms of professional expertise and human resources. The distribution of tasks among the dysphagia team members, which includes phoniatricians, otolaryngologists, and speech-language therapists, is flexible and overlapping. For assessing dysphagia, the (fibreoptic) flexible endoscopic evaluation of swallowing (FEES), with or without videofluoroscopy, is a pivotal diagnostic tool. This position paper aims to illustrate the phoniatrician's role in performing a FEES, which is an indispensable component of the diagnostic workup of patients suffering from oropharyngeal dysphagia. It is based on the current collaborative expert view of the Swallowing Committee of the Union of European Phoniatricians and a literature review. A FEES is one of the core competences of phoniatricians due to their endoscopic expertise and experience in the field of dysphagia and diseases of the upper aerodigestive tract. Therefore, the phoniatrician is an important member of the dysphagia team, for the medical diagnostics of the aerodigestive tract and dysphagia as well as for FEES. Phoniatric competence is especially important for head and neck cancer patients, infants, and complex cases.

Continuous versus intermittent intraoperative neuromonitoring in complex benign thyroid surgery: A retrospective analysis and prospective follow-up.

OBJECTIVES: To compare continuous (C-IONM) vs intermittent intraoperative neuromonitoring (I-IONM) in complex benign thyroid surgery, and to follow up patients with loss of signal (LOS) or unilateral vocal fold paralysis (UVFP). DESIGN: Retrospective clinical study, prospective case series. SETTING: University hospital and academic teaching hospital of Charité-University Medicine Berlin, Germany. PARTICIPANTS: C-IONM- and I-IONM-assisted thyroid surgery was conducted in 357 patients diagnosed with recurrent goitre, Graves' disease, complex hyperparathyroidism, cervical preoperation (anterior access) and LOS in primary operation (2-stage thyroidectomy). MAIN OUTCOME MEASURES: To evaluate the incidence of early postoperative and permanent UVFP, and to report the results of phonosurgical therapy in patients suffering from persisting dysphonia. RESULTS: In 346 patients enrolled (81.8% female, 18.2% male) with 613 nerves at risk (NAR) being monitored (409 I-IONM vs 204 C-IONM), early postoperative UVFP was observed in 10.5% of I-IONM vs 4.9% of C-IONM group (P < .05), permanent paralysis in 1.5% of I-IONM vs 1.0% of C-IONM group (P = .619). In total, 72 patients (21%) experienced pathological events (19 LOS < 100 µV, 53 transient or permanent UVFP). Three patients with permanent UVFP and persisting dysphonia received phonosurgery with stable improvements of all acoustic-aerodynamic parameters. CONCLUSION: Compared to I-IONM, C-IONM-application in complex benign thyroid surgery shows a significant reduction of transient UVFP and a non-significant trend in preventing permanent UVFP. In persistent UVFP with dysphonia, endolaryngeal phonomicrosurgery and transcervical laryngeal framework surgery are long-term effective treatment approaches to improve vocal function.

Phonomicrosurgery in Vocal Fold Nodules: Quantification of Outcomes in Professional and Non-Professional Voice Users.

There are few data demonstrating the specific extent to which surgical intervention for vocal fold nodules (VFN) improves vocal function in professional (PVU) and non-professional voice users (NVU). The objective of this study was to compare and quantify results after phonomicrosurgery for VFN in these patient groups. METHODS: In a prospective clinical study, surgery was performed via microlaryngoscopy in 37 female patients with chronic VFN manifestations (38±12 yrs, mean±SD). Pre- and postoperative evaluations of treatment efficacy comprised videolaryngostroboscopy, auditory-perceptual voice assessment, voice range profile (VRP), acoustic-aerodynamic analysis, and voice handicap index (VHI-9i). The dysphonia severity index (DSI) was compared with the vocal extent measure (VEM). RESULTS: PVU (n=24) and NVU (n=13) showed comparable laryngeal findings and levels of suffering (VHI-9i 16±7 vs 17±8), but PVU had a better pretherapeutic vocal range (26.8±7.4 vs 17.7±5.1 semitones, p<0.001) and vocal capacity (VEM 106±18 vs 74±29, p<0.01). Three months postoperatively, all patients had straight vocal fold edges, complete glottal closure, and recovered mucosal wave propagation. The mean VHI-9i score decreased by 8±6 points. DSI increased from 4.0±2.4 to 5.5±2.4, and VEM from 95±27 to 108±23 (p<0.001). Both parameters correlated significantly (rs=0.82). The average vocal range increased by 4.1±5.3 semitones, and the mean speaking pitch lowered by 0.5±1.4 semitones. CONCLUSIONS: These results confirm that phonomicrosurgery for VFN is a safe therapy for voice improvement in both PVU and NVU who do not respond to voice therapy alone. Top-level artistic capabilities in PVU were restored, but numeric changes of most vocal parameters were considerably larger in NVU.

Articulation handicap index: an instrument for quantifying psychosocial consequences of impaired articulation.

Structural, neurological and muscular diseases can lead to impairments of articulation. These impairments can severely impact social life. To judge health status comprehensively, this impact must be adequately quantified. For this purpose, the articulation handicap index (AHI) has been developed. Psychometric analyses referring to this index are presented here. The AHI was completed by 113 patients who had undergone treatment of tumours of the head or neck. The patients also gave a general self-assessment of their impairments due to articulation problems. Furthermore, tumour size, tumour location and kind of therapy were recorded. Missing data were analysed and replaced by multiple imputation. Internal structure was investigated using principal component analysis (PCA); reliability using Cronbach's alpha. Validity was investigated by analysing the relationship between AHI and general self-assessment of impairments. Moreover, the relationships with tumour size, tumour location and kind of therapy were analysed. Only 0.12 % of the answers to the AHI were missing. The Scree test performed with the PCA results suggested one-dimensionality with the first component explaining 49.6 % of the item variance. Cronbach's alpha was 0.96. Kendall's tau between the AHI sum score and the general self-assessment was 0.69. The intervals of AHI sum scores for the self-assessment categories were determined with 0-13 for no, 14-44 for mild, 46-76 for moderate, and 77-120 for severe impairment. The AHI sum score did not systematically relate to tumour size, tumour location or kind of therapy. The results are evidence for high acceptance, reliability and validity.

Teaching laryngeal electromyography.

To achieve consensus in the methodology, interpretation, validity, and clinical application of laryngeal electromyography (LEMG), a working group on neurolaryngology from the European Laryngological Society (ELS) was founded in 2010. The main task of the working group was to teach key techniques like LEMG procedures. The objective of this study was to collect information on the teaching techniques used and describe them. A multicenter registry was created to analyze the data collected from LEMGs in 14 departments. We screened how often different departments participated in teaching events. Teaching events were classified retrospectively: presentations at conferences and meetings; workshops with hands-on training on patients; workshops with hands-on training on animal models; workshops with hands-on training on anatomic specimens; and supervision by experts to perform LEMG together. Both, supervision to perform LEMG together and the total number of PCA-LEMGs (r = 0.713), as well as supervision to perform LEMG together and the PCA/total-number-of-LEMG ratio (r = 0.814) were correlated significantly (p < 0.05). Similarly, the sum of teaching events was correlated significantly with the total number of PCA-LEMGs (r = 0.605), and so did the sum of teaching events with the PCA/total-number-of-LEMG ratio (r = 0.704). Participation in hands-on training in humans was correlated significantly with the PCA/total-number-of-LEMG ratio (r = 0.640). The data presented herein suggest that multimodal teaching techniques are most effective. To promote multimodal learning an interactive webpage ( http://www.lemg.org) providing videos and animations, and the possibility to discuss cases with other experts was established.
