An integrated rigid fixation orbital expander has a coupling tunnel, an injection port, and a substantially spherically shaped expansion chamber. The coupling tunnel is configured with opposing side walls, a top wall and a bottom wall. The top wall of the coupling tunnel may have a depression denoting a mid-point of the coupling tunnel and serves as an entry point to introduce a needle for injection. The depression lines up with a hole on the vertical arm of a plate. The plate may glide within the coupling tunnel to align the depression with a desired hole in the plate. The injection port has a floor and a dome and a plurality of channels. The floor of the injection port may have a backstop plate to block a needle from further penetration. The dome of the injection port is connected to the bottom wall of the coupling tunnel.
