Laryngeal Diseases Categories.
 |
Granuloma, Laryngeal - A polypoid granulomatous projection into the lumen of the larynx. |
|
Laryngeal Edema - Edema of any region of the larynx from a variety of causes. In the earliest stages it may be difficult to differentiate from infection, although mucosal injection and erythema are found more often in the latter. Allergic edema may result as a response from provocation induced by foods, inhalants, and drugs. The entire respiratory tract or only an isolated portion of the larynx may be affected. Laryngeal edema may also be hereditary. Other possible causes of laryngeal edema include increased capillary pressure due to superior vena cava syndrome, internal jugular vein ligation, lowered plasma osmotic failure induced by renal failure, impaired lymphatic flow, and increased capillary permeability to proteins. (From Paparella et al., Otolaryngology, 3d ed, p2253) |
|
Laryngismus - Spasm of the larynx. |
|
Laryngitis - Inflammation of the larynx. This condition presents itself with dryness and soreness of the throat, difficulty in swallowing, cough, and hoarseness. |
|
Laryngostenosis - Stricture or narrowing of the larynx. This condition may be developmental or acquired; with progressive respiratory difficulty as a symptom. |
|
Vocal Cord Paralysis - Paralysis of one or both vocal cords, which produces hoarseness or aphonia. This condition may be caused by diseases of the medulla (e.g., LATERAL MEDULLARY SYNDROME), VAGUS NERVE, or recurrent laryngeal nerve. Neuromuscular junction diseases and local myopathic processes may also affect vocal cord function. (Adams et al., Principles of Neurology, 6th ed, p1380) |
|
Voice Disorders - Disorders of voice pitch, loudness, or quality. Dysphonia refers to impaired utterance of sounds by the vocal folds. |
