Ch 8 Voice Disorders Flashcards
Organic voice disorder
Caused by some physical condition that has impacted the structure and/or function of the larynx.
Functional voice disorder
Typically the result of particular behaviors a person is doing or a reaction to some organic disease or traumatic event that has placed the larynx in a less than optimal condition.
Neurological voice disorder
A result of an impairment to either the central nervous system or the peripheral nervous system.
Tumors
Can appear on the vocal folds and can be either benign or malignant.
Polyps
A benign tumor often found in the larynx which can protrude from the vocal folds causing an interference with vocal fold contact.
Vocal fold nodules
Usually small, sessile, slightly pink or grayish white protrusions located bilaterally, opposite each other, at the junction or the anterior and middle thirds or the entire length of the vocal folds.
Papillomata
Exposure to the human papilloma virus (HPV). There are two types, one being hard and the other being soft. These lesions arise from the mucous membranes and may be found in the pharynx, in the trachea, and at other sites, including the larynx. They are common benign neoplasms that, when located on the vocal folds, usually cause dysphonia.
Carcinoma
A malignant tumor that can grow on one or both vocal folds and affect their vibration much as do polyps or papillomata.
Edema
Swelling caused by excessive fluid in the tissue. Can be caused by vocal abuse, localized diseases, and systemic disorders such as allergic reactions and endocrine disturbances.
Contact ulcer granuloma
Benign growths that are like a sore on the vocal folds. If inflammation continues, granulation tissue can develop on the ulcer, which can become large enough to prevent complete glottal closure.
Laryngeal web
Refers to a membrane extending usually from one vocal fold to the other. It can also occur at the level of the false vocal folds or below the glottis.
Cysts
Any closed cavity or sac, normal or abnormal, lined by epithelium, and especially one that contains a liquid or semisolid material. Voice is usually hoarse, breathy, and weak, similar to that heard with a polyp or other protrusion into the glottal space.
Voice rehabilitation
1) Listening skills 2) Mental hygiene 3) Physical hygiene 4) Posture and movement 5) Regulation of breathing for voice 6) Relaxation 7) Voice training
Voice training
1) Eliminate factors harmful to the voice 2) Find the best sounds 3) Reduce excessively tense phonation 4) Increase phonatory efficiency 5) Modify vocal pitch 6) Increase vocal loudness 7) Alter vocal resonance
Artificial larynges
Two types, pneumatic and electronic. Pneumatic instruments use pulmonary air, are hand held, and have an air supply tube, sound source, and sound conducting tube. Electronic instruments are more common because they are generally easier to use and maintain.
