Vocal fold paresis: Medical specialists’ opinions on standard diagnostics and laryngeal findings

摘要

Purpose There is still no clear consensus on the diagnostic value of specific laryngeal findings in patients with suspected vocal fold paresis (VFP). The aim of the study was to establish expert opinion on criteria for the diagnosis of VFP in Europe. Methods A cross-sectional survey using the questionnaire introduced by Wu and Sulica for US American experts was addressed to laryngeal experts in Germany, Austria, and Switzerland and in a second survey wave to members of the European Laryngological Society. Results 100 respondents returned survey 1 (response rate 47.2%). 26% worked at a university department. 28% regularly used laryngeal electromyography (LEMG). A pathologic test results in LEMG was considered to have the strongest positive predictive value for VFP (79?±?23%), followed by a decreased vocal fold abduction (70?±?29%), decreased vocal fold adduction (61?±?34%), and atrophy of the hemilarynx (61?±?31%). The multivariate analysis showed the predictive value of LEMG was estimated lower by respondents from non-university hospital ( β ?=???16.33; confidence interval (CI)?=???25.63 to ??7.02; p ?=?0.001) and higher in hospitals with higher frequency of VFP patients per months ( β ?=?1.57; CI?=???0.98 to 2.16; p ?
