Although its role is frequently stressed in acoustic profile for vocal emotion, sound intensity is frequently regarded as a control parameter in neurocognitive studies of vocal emotion, leaving its role and neural underpinnings unclear. To investigate these issues, we asked participants to rate the angry level of neutral and angry prosodies before and after sound intensity modification in Exper...

Vocalization is rare among non-avian reptiles, with the exception of the crocodilians, the sister taxon of birds. Crocodilians have a complex vocal repertoire. Their vocal and respiratory system is not well understood but appears to consist of a combination of features that are also found in the extremely vocal avian and mammalian taxa. Anatomical studies suggest that the alligator larynx is ab...

OBJECTIVE/HYPOTHESIS Glottal closure and symmetrical thyroarytenoid stiffness are two important functional characteristics of normal phonatory posture. In the treatment of unilateral vocal cord paralysis, vocal fold medialization improves closure, facilitating entrainment of both vocal folds for improved phonation, and reinnervation is purported to maintain vocal fold bulk and stiffness. A comb...

INTRODUCTION AND OBJECTIVES Vocal fold paralysis (VFP) is a relatively common cause of stridor and dysphonia in the paediatric population. This report summarises our experience with VFP in the paediatric age group. METHODS All patients presenting with vocal fold paralysis over a 12-month period were included. Medical charts were revised retrospectively. The diagnosis was performed by flexible...

Bilateral vocal cord palsy is one of the causes that trigger nocturnal stridor and obstructive sleep apnea (OSA), and three cases of OSA due to bilateral vocal cord paralysis have been described in the medical literature. In 1987, Ruff et al.1 reported a case of bilateral vocal cord palsy and sleep apnea in a patient with type I Chiari malformation. In 1996, McBrien et al.2 reported a case of b...

BACKGROUND Perioperative examination ofthe vocal folds with flexible fiberoptic laryngoscopy is not always feasible. Prior studies suggest vocal fold ultrasound may provide a useful screening tool, however, correlation to laryngoscopic findings is necessary. The purpose of the case series was to validate vocal fold ultrasound in the adult population and to correlate the ultrasound findings to t...

Vocal cord dysfunction is a well recognized respiratory condition in which adduction of the vocal cords during either inspiration or expiration, or both, causes functional airways obstruction. Diagnosis is usually made by laryngofibreoscopy, however treatment of this condition has generally been unsatisfactory, requiring a multi-disciplinary approach consisting of speech therapy, psychological ...

More than half of patients who present with the symptom of hoarseness show benign vocal fold changes. The clinician should be familiar with modern diagnostic and therapeutic possibilities of benign vocal fold changes in order to ensure an optimal and individualized attention to voice patients. Basic knowledge of the etiology are provided for targeted phonosurgical or conservative therapy. This ...
