The larynx, or voice box, regulates the intersection of the respiratory and digestive tracts, and it houses the vocal cords. Thus, it controls vocal production, swallowing and breathing. Laryngology is the study and treatment of disorders of the larynx, which includes:
At the University of Maryland, our ear, nose and throat program includes a team of highly trained laryngology specialists who provide expert patient care as well as leadership in education and research.
Our team consists of physicians, physician assistants, nurses, speech-language pathologists and vocal pedagogues.
Innovative Diagnostic and Treatment Options
In recent years, there has been a rapid growth in technology for imaging of the larynx and endoscopic surgical techniques. These advances allow accurate examination and diagnosis of issues with the larynx.
State-of-the-art techniques include highly specialized micro-instrumentation, laser surgery, and other minimally invasive techniques. In addition, we investigate novel drug therapies and delivery systems for treatment of the larynx.
Disorders of the larynx generally lead to vocal dysfunction, difficulty swallowing or breathing. They can be caused by:
Cancerous or Non-Cancerous Lesions
- Polyps, nodules and cysts
- Enlarged or swollen veins in the esophagus
- Squamous cell carcinoma
- Salivary gland cancer
- Neuroendocrine cancers
- Vocal fold paralysis
- Neuromuscular disorders
- Parkinson's disease
- Myasthenia gravis
- Spasmodic dysphonia
- Vocal fold fixation
- Airway stenosis, usually from endotracheal intubation
