The main etiological factor is persistent abuse in hyperkinetic extroverts. The habit of smoking is another of the main causal agents. The condition appears to occur more frequently in middle-aged women .

Pathological anatomy

The edges of the true membranous vocal cords, are diffusely presented by edematous masses. Histological examination shows that the edema is limited to the Rienke space, which appears very wide and filled with mucoid substance, almost devoid of cells , fibrous tissue and blood vessels .

Clinical manifestations

An intense hoarseness is constant , which varies according to the degree of edema; aphonia may appear intermittently . The timbre of the voice is low and tends to be monotonous, making singing impossible. Dyspnea and stridor may occur when the polyps are large, requiring emergency treatment for the obstruction.

The presence of pale symmetrical masses hanging in the form of sausages is observed on each membranous string. They are often approximate and seal the anterior glottis, so the passage of air is established only in the arytenoids. The masses are usually transparent pinkish gray, but the inflammation can cause a bright red coloration.


In patients with discrete polyposis, regression can be achieved by eliminating irritating factors and with intense voice therapy , however, in many cases it is convenient to practice surgical denudation of the strings, which can sometimes become a process. urgent, due to laryngeal obstruction.

During the operation, the mucosa and the glutinous content of the saccular lesions must be removed until reaching the free edge of the elastic cone. It is advisable to leave the mucosa of the anterior portion of a string intact, to avoid the formation of adhesions , on which occasion, the use of the operating microscope is important . After denudation of the vocal cords and healing , vocal reduction should be initiated.
