Replacement of both the original Provox (figure right) and the Provox2 voice prosthesis should be carried out by a medical professional trained in the procedure. A good view on the tracheostoma using the headlight is mandatory and a suction system is very helpful. Use good metal suction tube. One or two curved non-toothed hemostats should be at hand.
With the original Provox prosthesis good assistance during replacement in the outpatient office, preferably by a trained nurse, is recommended. The replacement of the Provox2 prosthesis is considerably easier and can be carried out without assistance.
