A surgical instrument assembly for making a shunt passage between the oesophagus and the surface of the neck, for accommodating a larynx prosthesis. The assembly includes a curved puncture needle, a prosthesis place holder and a placing needle, and optionally includes a tracheostoma template. The bent configuration of the puncture needle ensures correct formation of the shunt passage. The prosthesis place holder allows the shunt passage to heal up in the correct configuration. The placing needle provides for correct fitting and radiological checking of the place holder.
