Abstract
Teflon is commonly used to adduct immobile vocal cords in cases of unilateral recurrent nerve paralysis. However, its use can lead to considerable chronic inflammation at the site of the injection. Since Teflon is not encapsulated, particles can also be carried off and disseminated through the lymphatic system. This occurrence was found following Teflon injection in a 48-year-old man, resulting in laryngeal stenosis with tissue histology showing an impressive diffuse distribution of the Teflon particles and severe chronic inflammation. Our experiences have caused us to prefer the implantation of autologous materials in cases of unilateral recurrent nerve paralysis, particularly when patients have a long life expectation.
