Post-operative Hoarseness of Vocal Nodules

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...

The VHI Analysis of vocal polyps and vocal nodules

Objective: Explore the practical clinical significance and correlation of voice handicap index (VHI) for vocal polyps and vocal nodules, and further validate practicality of VHI. Methods: VHI of vocal cord polyp group (n = 35), vocal nodule group (n = 29), and control group (n = 22) was surveyed respectively. The VHI investigation included three categories of function (F), physiology (P) and em...

Rheumatoid nodules of the vocal folds.

Simulation of Human Phonation with Vocal Nodules

The geometric and biomechanical properties of the larynx strongly influence voice quality and efficiency. A physical understanding of phonation natures in pathological conditions is important for predictions of how voice disorders can be treated using therapy and rehabilitation. Here, we present a continuum-based numerical model of phonation that considers complex fluid-structure interactions o...
