Removing Silicon Implant After Rhinoplasty Revision?

The best and safest long-term surgical option is to replace the silicone implant with your own rib cartilage

Removal of silicone implant will produce your original nose. You may get some slight improvement from scar tissue giving a very slight raise of your bridge.

With your history of 2 prior surgeries, you do have a certain degree of scar tissue inside your nose.  The silicone implants do form a "capsule" over time, which may give you a small amount of height vs. your pre-surgery nose, but it will definitely be lower than it was with the implant in place.  You do still have excellent options without the use of an implant.  Using tissue from your own body, such as cartilage from your ear or rib, a revision rhinoplasty could be performed to give you the nose you want, but without the synthetic implant.   

The question is not whether you will get your old nose back exactly but how close you will come to its original shape. A lot of that depends on how big the silicone implant is and how thin the skin has become. But if the implant was only on the dorsum of the nose, its removal will bring the bridge height back down to its original level. The thinning of the nasal skin may give it a slightly different appearance however.

We cannot know if removal of the silicone implant will give you your 'old' nose back, though it is possible that the bridge will drop down and with some adjustment you can be closer to the true you. Much depends on the scar and what else might have been used to shape the bridge.
