Purpose: The goal of this study was to experimentally evaluate how compensating for the adverse acoustic effects of a posterior glottal opening (PGO) by increasing subglottal pressure and changing supraglottal compression, as have been associated with vocal hyperfunction, influences the risk of vocal fold (VF) trauma. Method: A self-oscillating…

Purpose: Laryngeal high-speed videoendoscopy (LHSV) has been recognized as a highly valuable modality for the scientific investigations of vocal fold (VF) vibrations. In contrast to stroboscopic imaging, LHSV enables visualizing aperiodic VF vibrations. However, the technique is less well established in the clinical care of disordered voices,…

Purpose: The purpose of this study is to familiarize speech-language-pathologists with the current state of the science regarding medialization laryngoplasty in the treatment of voice disorders, with emphasis on current evidence-based practice, voice outcomes, and future directions for research. Method: A literature review was performed in PubMed…

Purpose: To better define the clinical characteristics of idiopathic oromandibular dystonia, we studied voice, speech, and swallowing disorders and their impact on activities of daily living. Method: Fourteen consecutive patients with idiopathic oromandibular dystonia and 14 matched, healthy control subjects were included in the study. Results:…

Background: Physical and psychosocial challenges are common after total laryngectomy. The surgery leads to lifelong changes in communication, airway, swallowing and appearance. As we move towards health models driven by patient-centred care, understanding the differential impacts of surgical procedures on subgroups of patients can help improve our…

Background: Post-spinal cord injury (SCI), individuals may exhibit mild to moderate impairments in aspects of speech influenced by impaired respiratory support. However, limited research has been conducted into the impact of these impairments on activity and participation when living in the community. Aims: To examine the nature and extent of…

Speech-language pathology has different practice and research histories, standards, methods, and challenges in different countries and regions. Awareness of these different realities may contribute to the scientific development of the field and improve the services delivered to different populations. Sharing solutions to similar problems in…

Voice and swallowing dysfunction as a result of recurrent laryngeal nerve paralysis can be improved with vocal fold injections or laryngeal framework surgery. However, denervation atrophy can cause late-term clinical failure. A major determinant of skeletal muscle physiology is myosin heavy chain (MyHC) expression, and previous protein analyses…

Glottal stops are conveyed by an abrupt constriction at the level of the glottis. Tracheoesophageal (TE) speakers are known to have poor control over the new voice source (neoglottis), and this might influence the production of "glottal" stops. This study investigated how TE speakers realized "glottal" stops in abutting words…

Aims: To compare voice quality as defined by formant analysis using a sustained vowel in patients who have undergone a partial glossectomy with a group of normal subjects. Methods & Procedures: The design consisted of a single centre, cross-sectional cohort study. The setting was an Adult Tertiary Referral Unit. A total of 26 patients (19…
