How much to downsize in case of shortening of the fistula tract
Problem: during retrograde insertion the guide wire gets stuck in the neoglottis
During the retrograde replacement of the Provox prosthesis, the guide-wire may become entrapped in the pharyngeal mucosal wall. By applying a smooth introduction movement and slight pressure, the guide wire will generally bend near the tip and still slide upward through the pharynx. "Swallowing" the guide wire and picking it up through the TE fistula with a forceps is another option.
