I have complications with 44 year old chin implant. How difficult are they to remove?

It would be pretty routine to remove the implant you have, and you could have it replaced if you'd like.

Rubberized silicone chin implants have the longest track record of longevity and safety, and to my knowledge, that was the only alloplastic material available in the 1970s. Removal of silicone chin implants may be straightforward for an experienced facial plastic surgeon. In our practice, removal or placement is performed through a small external incision under your chin, and surgery may take under 30 minutes.Hope this is helpful for you.Dr. Joseph

Chin implants are commonly performed along with a rhinoplasty, neck liposuction, or face lift in appropriate patients. Occasionally, these chin implants need to be modified, changed, or removed. The difficulty of removing or modifying a chin implant is largely dependent on the material of the implant. Solid silicone implants are easy to remove, while other materials are much more difficult. It would be difficult to determine the material on physical examination alone, and a CT scan or imaging might help provide information. Speak with a chin implant surgeon to perform a comprehensive evaluation and determine appropriate options for you.Best,Dr. Chaboki 

Without medical records available, there is no way to know what type of chin implant you had placed 44 years ago.  The only way to know for sure would be during surgery.  If you haven't already, I would consult with a facial plastic surgeon or plastic surgeon who has experience with chin implants.  You may not need to have the implant removed.  If there is no other treatment to try and help, it should be possible to remove the implant.  

Such an old chinimplant would be easy to remove. Most likely it is sitting high particularly if it was placed originally through an intraoral approach. It may be solid silicone or gel-filled but either way it can be removed.

It is hard to give you an answer.  In the 1970s glass and gel filled implants were used.  If your implant is gel filled, it will be relatively easy to remove and replace with a filler (no implant).  If the implant is glass, they can not be removed as they fuse to the bone.  See someone, such as a facial plastic surgeon, who performs a lot of chin implants.
