Vocal Hoarseness and a Subglottic Mass

Vocal Hoarseness and a Subglottic Mass

We report a patient with tracheopathia osteoplastica (TPO), a rare or perhaps underrecognized disorder, detected in approximately 1 in every 2000 to 5000 patients who undergo bronchoscopy. TPO is marked by proliferation of bony and cartilaginous spurs leading to airway stenosis. Multiple submucosal cartilaginous and osseous nodules can develop in the respiratory tract and may involve the entire...

A case of hoarseness and vocal cord immobility.

40-year-old woman presented to the oto-laryngology clinic with a 7-week history of hoarseness. The symptom had occurred suddenly, and no upper respiratory tract infections or history of vocal overuse immediately preceded the onset. Her voice had not improved during the intervening weeks. She reported symptoms of potential aspiration when drinking thin liquids, and she found herself short of bre...

Hoarseness as a sign of possible nonspecific mucosal hyperreactivity in vocal tract.

The aim of the present paper was to evaluate the possible impact of methacholine challenge on the voice and vocal tract in 10 patients reporting hoarseness due to presumable hyperreactivity to some environmental factors. Ten age and gender-matched healthy subjects served as controls. Methacholine was used for hypersensitivity challenge and saline solution (0.9% NaCl) as control substance. Subje...

A translating and rotating mass model of the vocal folds

The motion of a vocal fold is modelled with two mechanical resonators. One is for the translational movement of the body of the fold and is driven by the spatial average pressure in the glottal constriction. The other is rotational, it models the covering mucosa and is driven by the axial pressure gradient. Unlike the classical Ishizaka-Flanagan two-mass model, these resonators are mechanically...
