Sizers, Tracheoesophageal Speech Prosthesis
Definition : Surgical sizers designed to facilitate the selection of an appropriate size (i.e., length) of tracheoesophageal speech (voice) prosthesis. The sizer measures the distance of the puncture between the trachea and the esophagus. These sizers typically consist of a calibrated (e.g., 16 or 20 Fr diameter, marked in millimeter increments that correspond with prosthesis sizes), and a hollow, silicone tube that is similar to the prosthesis but without a slit-valve; the sizer is usually placed using a disposable inserter. The prosthesis is selected according to the length determined by the sizer and then inserted. Voice prosthesis tracheoesophageal sizers are used in surgical procedures intended to insert prostheses to make speech possible for patients after tracheostomy procedures.
