“…The differences in dysphonia prevalence in the literature could be explained by the absence of standardized questionnaires to define dysphonia. Our result is also confirmed by the difference of phonation quotient between asthmatic and control group which has been shown to be higher in disordered voice 28 …”

“…Our result is also confirmed by the difference of phonation quotient between asthmatic and control group which has been shown to be higher in disordered voice. 28 Dysphonia prevalence was lower when we used the GRBAS scale. This suggests that the handicap induced by dysphonia is not always quantified by perceptual analysis of the voice.…”

Background Dysphonia is a frequent comorbidity of asthma and has been suggested to be a local side effect of inhaled corticosteroids due to laryngeal candidiasis. We hypothesized that dysphonia in asthmatics was not due to laryngeal organic lesions but to laryngeal dysfunction during phonation (LDP). Objective We compared the frequency of LDP in female asthmatic patients treated with inhaled corticosteroids to female controls. Methods We compared 68 asthmatic female patients to 53 female control subjects. Pulmonary function tests were performed and the asthmatic patients classified according to the level of inhaled corticosteroids. Dysphonia was defined as a Vocal Handicap Index ≥18 or GRBAS score ≥2. All patients underwent video laryngo‐strobe examination, analyzed blindly and separately by two otolaryngologists, describing mucosal changes, LDP, or Organic lesions linked to Laryngeal Dysfunction during Phonation (OLDP). Results 66.2% of the asthmatic patients exhibited dysphonia and 11.3% of controls ( p < 0.001). No laryngeal candidiasis was found, only 3 patients presented laryngeal mucosa inflammation. LDP was observed in 60.3% of asthmatic patients and 18.9% of controls ( p < 0.001), and no difference was found for OLDP (11.8% vs. 13.2%). No association was made between LDP, the dosage of inhaled corticosteroid, and bronchial obstruction. Conclusions Asthmatic patients were more dysphonic than control subjects. This phenomenon was not explained by mucosal inflammation, laryngeal candidiasis or OLDP. Asthmatic patients had more LDP than controls. There was no relation between LDP, inhaled corticosteroids dosage or bronchial obstruction. These results change our view of inhaled corticosteroid side effects in female asthmatic patients.

Purpose: The purpose of this clinical focus article is to summarize a community discussion about the practical implementation of recommended vocal function measures by practicing speech-language pathologists specializing in the treatment of voice and upper airway disorders, review common barriers and challenges to implementation, and suggest opportunities for further education and discussion. Method: An online discussion was held with members of American Speech-Language-Hearing Association Special Interest Group (SIG) 3 to facilitate discussion regarding participants' experiences implementing vocal function assessment (acoustic and aerodynamic assessment) in their practice settings. The discussion was based on the expert panel consensus paper by Patel et al. (2018), which provided recommendations for a minimum core set of vocal function measures. Results: Discussion topics included standardization methods, environmental factors, preferred hardware and software, tasks and measures, interpretation, and infection control. Participants reported that the recommendations of the consensus paper provide a useful guideline for obtaining a core set of reliable and valid measures. They also reported facing barriers in meeting these recommendations due to varying practice settings and resources. Conclusions: Variations in instrumental assessment may arise due to differences in clinic models, testing environments, accessible equipment, allotted time, and clinician opinion. During the discussion, participants emphasized the need for further education and discussion on the implementation of vocal function assessment, particularly regarding adaptations for different clinical models, low-cost and low-tech alternatives, synthesis of findings, and the relevance of additional or omitted measures in specific situations. To address these concerns, it is recommended that the SIG 3 community delve deeper into this topic, open additional discussion about various topics cited as barriers to vocal function assessment implementation, and create ongoing educational opportunities for clinicians, especially for those who lack access to a voice-specialized clinical fellowship program or mentorship by a specialized clinical expert.
