Abstract: To develop and validate a laryngectomee-specific questionnaire to investigate swallowing function. This paper describes the generation of questionnaire items, pretesting with laryngectomees and a preliminary validation. This study employed 2 phases: questionnaire development and questionnaire validation. Items were developed from patient (n = 10) and clinician (n = 6) focus groups. Content checking, acceptability and face validity were determined through pretesting with 10 laryngectomees and via consensus feedback from 35 speech and language therapists. During preliminary validation, the 17-item final questionnaire was administered to 3 different groups. Discrimination amongst groups was established by comparing questionnaire responses of a laryngectomee group (n = 19) with known dysphagic (n = 19) and non-dysphagic groups (n = 20). Questionnaire responses from the reference dysphagic group were compared with an instrumental assessment of swallowing, the modified barium swallow (MBS). Large urban teaching hospital. Speech and language therapists, laryngectomees, non-dysphagic volunteers, post-radiotherapy dysphagic patients. Preliminary validation of SOAL questionnaire. Normal, laryngectomee and dysphagic groups had significantly different SOAL scores, as did laryngectomees with different degrees of swallowing impairment (Kruskall Wallis, P << 0.001). The subjective SOAL score had a strong positive correlation with the reference measure of ratings on the MBS (r = 0.5 P = 0.03). The swallowing outcome after laryngectomy (SOAL) questionnaire is a simple, self-administered tool to assess swallowing function post-total laryngectomy. Further specific testing with a laryngectomy cohort is necessary for full validation. Its potential value lies in screening for dysphagia in clinics or during long-term follow-up of laryngectomees.

Abstract: SARS-CoV-2, a highly contagious severe acute respiratory syndrome, has spread to most countries in the world and resulted in a change to practice patterns for the assessment and diagnosis of people with voice disorders. Many services are transitioning to telehealth models to maintain physical distancing measures and conserve personal protective equipment used by healthcare workers during laryngoscopy examinations. The speech–language pathology primary contact (SLPPC) assessment for patients referred to ear, nose and throat (ENT) services in Australia has been shown to reduce waiting times for assessment while streamlining access to ENT assessment and allied health practitioner treatment pathways. A prospective observational cohort study will see patients in a newly developed telehealth model which uses the principles from a usual care SLPPC assessment protocol. Participants will be offered an initial telehealth assessment (speech–language pathology primary contact telehealth (SLPPC-T)) prior to being prioritised for a face-to-face laryngoscopy assessment to complete the diagnostic process. The telehealth assessment will collect sociodemographic information, personal and family medical history, key symptoms, onset and variability of symptoms, red-flag signs or symptoms for laryngeal malignancy, and clinical voice assessment data for auditory–perceptual and acoustic analysis. The study outcomes include (1) association of signs, symptoms and specific voice measures collected during SLPPC-T with voice disorder classification provided after laryngoscopy (2) degree of concordance between voice disorder classification after SLPPC-T and after laryngoscopy (3) health service and patient-related costs and health outcomes of the SLPPC-T (4) patient and stakeholder views and beliefs about the SLPPC-T process. Ethical approval has been granted prior to commencement of the study enrolment by the Gold Coast Hospital and Health Service Human Research Ethics Committee (reference number HREC/2020/QGC/62832). Results will be shared through the publication of articles in peer-reviewed medical journals and presentation at national and international scientific meetings. ACTRN12621000427875.

Abstract: The aim of the study was to investigate whether the type of instrumental swallowing examination (Fibreoptic Endoscopic Evaluation of Swallowing (FEES) or videofluoroscopy) influences perception of post-swallow pharyngeal residue. Prospective, single-blind assessment of residue from simultaneous videofluoroscopy and FEES recordings. All raters were blind to participant details, to the pairing of the videofluoroscopy and FEES examinations and to the other raters' scores. Tertiary specialist ENT teaching hospital. Fifteen adult participants consecutively recruited seven women and eight men aged between 22 and 73, mean age 53. All participants underwent one FEES examination and one videofluoroscopy examination performed simultaneously. referred to speech and language therapy for assessment of dysphagia. nil by mouth or judged to be at high risk of aspiration. The FEES and videofluoroscopy examinations were recorded simultaneously. Fifteen speech and language therapists independently scored pharyngeal residue as none, coating, mild, moderate or severe. All examinations were scored twice by all raters. Intra- and inter-rater agreement were similar for both examinations. There were significant differences between FEES and videofluoroscopy pharyngeal residue severity scores (anova, P < 0.001). FEES residue scores were consistently higher than videofluoroscopy residue scores. Pharyngeal residue was consistently perceived to be greater from FEES than from videofluoroscopy. These findings have significant clinical implications as FEES and videofluoroscopy findings are used to judge aspiration risk and to make recommendations for oral intake. Further research is required to examine the impact of FEES and videofluoroscopy examinations on treatment decisions.

Abstract: Ear, Nose and Throat (ENT) primary contact models of care use audiologists as the first triage point for children referred to ENT for middle ear and hearing concerns and have shown reduced waiting time, improved ENT surgical conversion rates and increased service capacity. This study aimed to investigate ‘safety and quality’ of the model by looking at agreement between audiologists’ and an ENT’s clinical decisions. We performed an inter-rater agreement study on diagnosis and management decisions made by audiologists and an ENT for 50 children seen in an Australian hospital’s ENT primary contact service, and examined the nature and patterns of disagreements. Professionals agreed on at least one site-of-lesion diagnosis for all children (100%) and on the primary management for 74% (Gwet’s AC1 = 0.67). Management disagreements clustered around i) providing ‘watchful waiting’ versus sooner medical opinion (18%), and ii) providing monitoring versus discharge for children with no current symptoms (8%). There were no cases where the audiologist recommended discharge when the ENT recommended further medical opinion. Our novel research provides further evidence that Audiologist-led primary contact models for children with middle ear and hearing concerns are safe as well as efficient.

Abstract: Previous research has found that high‐frequency energy of speech signals decreased while wearing face masks. However, no study has examined the specific spectral characteristics of fricative consonants and vowels and the perception of clarity of speech in mask wearing. To investigate acoustic–phonetic characteristics of fricative consonants and vowels and auditory perceptual rating of clarity of speech produced with and without wearing a face mask. A total of 16 healthcare workers read the Rainbow Passage using modal phonation in three conditions: without a face mask, with a standard surgical mask and with a KN95 mask (China GB2626‐2006, a medical respirator with higher barrier level than the standard surgical mask). Speech s les were acoustically analysed for root mean square (RMS) litude ( A RMS ) and spectral moments of four fricatives /f/, /s/, /ʃ/ and /z/ and litude of the first three formants (A1, A2 and A3) measured from the reading passage and extracted vowels. Auditory perception of speech clarity was performed. Data were compared across mask and non‐mask conditions using linear mixed models. The A RMS of all included fricatives was significantly lower in surgical mask and KN95 mask compared with non‐mask condition. Centre of gravity of /f/ decreased in both surgical and KN95 mask while other spectral moments did not show systematic significant linear trends across mask conditions. None of the formant litude measures was statistically different across conditions. Speech clarity was significantly poorer in both surgical and KN95 mask conditions. Speech produced while wearing either a surgical mask or KN95 mask was associated with decreased fricative litude and poorer speech clarity. Previous studies have shown that the overall spectral levels in high frequency ranges and intelligibility are decreased for speech produced with a face mask. It is unclear how different types of the speech signals that is, fricatives and vowels are presented in speech produced with wearing either a medical surgical or KN95 mask. It is also unclear whether ratings of speech clarity are similar for speech produced with these face masks. Speech data collected using a real‐world, clinical and non‐laboratory‐controlled settings showed differences in the litude of fricatives and speech clarity ratings between non‐mask and mask‐wearing conditions. Formant litude did not show significant differences in mask‐wearing conditions compared with non‐mask. Wearing a surgical mask or a KN95 mask had different effects on consonants and vowels. It appeared from the findings in this study that these masks only affected fricative consonants and did not affect vowel production. The poorer speech clarity in these mask‐wearing conditions has important implications for speech perception in communication between clinical staff and between medical officers and patients in clinics, and between people in everyday situations. The impact of these masks on speech perception may be more pronounced in people with hearing impairment and communication disorders. In voice evaluation and/or therapy sessions, the effects of wearing a medical mask can occur bidirectionally for both the clinician and the patient. The patient may find it more challenging to understand the speech conveyed by the clinician while the clinician may not perceptually assess patient's speech and voice accurately. Given the significant correlation between clarity ratings and fricative litude, improving fricative signals would be useful to improve speech clarity while wearing these medical face masks.

Abstract: A challenge for clinicians and researchers in laryngology is a lack of international consensus for an agreed framework to classify homogenous groups of voice disorders. Consistency in terminology and agreement in how conditions are classified will provide greater clarity for clinicians and researchers. This scoping review aimed to examine the published literature on frameworks, terminology, and criteria for the classification of voice disorders. Seven online databases (MEDLINE, Embase, CINAHL, PsycInfo, Scopus, Cochrane Collaboration, Web of Science) and grey literature sources were searched. Studies published from 1940 to 2021 were included if they provided a descriptive detail of a classification framework structure and described the methodological approaches to determine classification. A narrative synthesis of the main concepts including terminology, classification criteria, grouping of conditions, critical appraisal items and gaps in research was undertaken. A total of 2,675 publications were screened. Twenty sources met inclusion criteria, including published articles and grey literature. Thirty-five classification groups and over 150 sub-groups were described. The classification group labels, and criteria for inclusion of conditions varied across the frameworks. Several key themes in terminology and criteria useful for classification are discussed, and a core set of suggested terms and definitions are presented. The quality of research on classification frameworks for voice disorders is low and not one system encompasses all voice disorders across the whole spectrum. Continued high quality research using consensus methodology and inter-rater reliability scores is recommended to develop and test an internationally agreed classification framework for voice disorders.
