The risk of developing a "Witch's chin" after chin implant removal is minor. Such risk is higher if the implant is not replaced. If the problem is noted during surgery, re-suspension of the the muscle can be attempted. The fact that your plastic surgeon recognized and informed you of the risk speaks to his/her thoroughness.
Ultimately you will have to weigh the benefits vs. the risk of surgery. It may be helpful to obtain a second opinion. During the clinical examination the surgeon can gain a appreciation of the likelihood of complications associated with implant replacement.
