Among the benign tumors of the larynx are more common:
Fibroma (fibrous polyp) usually occurs at the free edge of the vocal folds at the border between the anterior and middle thirds, is growing very slowly, often does not reach large sizes. The main symptoms are hoarseness, and possibly a cough. The voice may change, if fibroma has a long stem and easily dismissed. Surgical treatment, recurrences may, if left a piece of the tumor.
Papillomas are single or papillary excrescences, resembling a cauliflower. Most often they are located on the vocal folds. The most common papillomavirus found in age from 1.5 to 5 years. By the beginning of puberty, they often disappear. The main symptoms are hoarseness, reaching up to aphonia, and progressive shortness of breath, which may go to suffocation with an increase in the tumor. Treatment of surgery. Relapse after treatment are often, but the tendency to recur individual: in some cases, warts have to be removed several times a year, in others - a few years.
Cysts are found in the larynx are not frequent. They are usually localized on the surface of the laryngeal epiglottis. More often cysts develop as a result of occlusion of the mucous glands, increase slowly, do not reach large sizes. Small cysts usually do not cause any symptoms and require no treatment.
Angioma of larynx originate from dilated blood vessels (hemangioma, lymphangioma). They can be localized to the voice, sometimes in the ventricular folds or cherpalonadgortannyh. Grow slowly, are usually small in size. Sometimes the tumor reaches a large size and hanging into the lumen of the larynx, disrupting breathing. Angiomas of small dimensions concerned only in the case of localization at the vocal cord - thus there is hoarseness. Medium and large sizes angiomas and other functions violate the larynx, so they must be removed.
