Crooked chin implant? Should I be concerned?

The best way to tell if a chin implant is in the incorrect position is to examine the patient.  Normally by looking at the implant and feeling it in the patient, the position can be determined.  If you feel that your implant is in the wrong position and your surgeon feels otherwise, you could always get a second opinion.  

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  You should continue to follow up and have this discussion with your chin implant surgeon.  The wings should follow the bottom edge of the jaw line on either side of the chin.  If you are worried that one or both wings might be too high, you can have a 3-D facial scan (typically available at cosmetic dentists offices that do dental implants) to show the facial skeleton, implant location and nerve foramen (place where the sensory nerves exit the jaw bone).  This will allow you to see where the implant and wings are located.   When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin".  
 Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty (requires extensive tissue dissection, bone cuts and placement of metal screws and plates to secure the cut segments of bone).  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  Hope this helps.
