title: Teflon paste implant in unilateral vocal cord paralysis: CT characteristics.
abstract: Laryngeal Teflon paste implants are routinely used to lessen the manifestations of unilateral vocal cord paralysis. Although the Teflon paste is not visible on plain radiography, it is detected on CT as a high density area. Computed tomography may be useful as a baseline study to determine the amount and location of the Teflon paste and also to detect complications such as acute edema, migration of paste, or chronic granuloma formation.
