Figure A.7: The Provox2 voice prosthesis with both flanges fully unfolded while still attached to the inserter with the security strap. After checking the proper position of the voice prosthesis the strap should be cut off. On exhaling and occlusion of the stoma sound will be generated.

When the clinician is assured of proper fixation the security strap is cut off and the patient is ready to use the prosthesis (figure A.7). In the case that the tracheal flange does not unfold completely or the device is still completely in the esophagus a hemostat is needed to pull the prosthesis through the TEF towards the tracheostoma to deliver the tracheal flange. This is a minor complication but can be troublesome to those with minimal experience with backloading voice prostheses.
