We present an acute stridor secondary to bilateral vocal cord paresis in a patient with demyelinating form (type I) of hereditary motor and sensory neuropathy (HMSN). Management problems are discussed and HMSN reviewed.

OBJECTIVES Hyperkinetic laryngeal behaviors may be used to achieve glottal closure in the presence of vocal cord disorders. In adults, the Glottal Function Index (GFI) is a validated self-administered survey used to evaluate glottal insufficiency. In children, the relationships between glottal closure and vocal cord lesions have not been examined. We undertook to evaluate the efficacy of the GF...

OBJECTIVE Congenital high airway obstruction syndrome (CHAOS) normally has a dire prognosis due to laryngeal atresia and association with other anomalies. However, rare cases with an isolated tracheal membrane have been described. We assessed systematically the larynx and vocal cords in fetuses with CHAOS, with the goal of identifying such cases and attempting fetoscopic deobstruction. METHOD...

OBJECTIVE Laryngomalacia is the most common cause of congenital stridor. Laryngomalacia may be associated with other structural and functional airway lesions. While previous studies suggested a 10-45% rate of synchronous airway lesions (SALs), the exact rate and it's clinical significance is unknown. The purpose of this study was to determine the prevalence of SALs below the glottic level in co...

The proper development of the vocal cords requires embryos to contain a certain number of progenitor cells, and mutations that lead to an overflow of cells can cause malformations of the voice box.

Introduction: Reinke’s edema, also known as polypoid degeneration of vocal cords, is a bilateral, symmetrical swelling the whole membranous part cords. Surgery has been mainstay treatment for edema. Thus, patients are often left with practically no non-invasive option. Case Summary: This case 40-year-old male, teacher, who presented hoarseness voice 1 year and opted homeopathic when he was advi...

This case concerns an elite road cyclist who complained of occasional dyspnoea and inspiratory difficulty during intense exercise. Clinical examination was normal and the final diagnosis was vocal cord dysfunction, a paradoxical closure of the vocal cords during inspiration which is highly associated with inspiratory stridor at high rates of ventilation. Awareness by the sports physician of thi...
