Gelfoam paste injection for vocal cord paralysis: temporary rehabilitation of glottic incompetence

Vocal cord paralysis frequently results in open glottic incompetence with aspiration, an ineffective cough, and poor voice production. Glottic competence can be restored temporarily be injecting the true vocal cord with Gelfoam paste. This clinical use of Gelfoam for temporary rehabilitation is indicated in : 1) situations in which paralysis may be temporary, 2) patients for whom an open operative procedure must be delayed, and 3) circumstances in which it is desirable to determine the effect of vocal cord injection prior to placement of nonabsorbable material. The injection of Gelfoam paste results in minimal tissue reaction. Absorption is gradual over a period of six to ten weeks, allowing time for some glottic compensation. The injection may be repeated without adverse effects until the paralysis resolves or intervention of a permanent nature is indicated.
