Injection of the steroid Kenalog, usually into inflammatory lesions. Kenalog is the trade name for a suspension of triamcinolone acetonide, a steroid that is eight times more potent, milligram for milligram, than prednisone. In laryngology, Kenalog at 40mg per ml is injected into the greater cornua of the hyoid bone to treat the condition hyoidynia, or into areas of inflammatory stenosis, or (occasionally) into symptomatic and very large contact granulomas, or (even less commonly) into vocal cords with rheumatoid nodules.
Keratosis is a lesion seen most often on the mucosa of the vocal cords. It typically appears as a white patch of leukoplakia. Histologically one sees heaping up of the surface layer of cells, which do not mature and “slough off” as they should.
