Chin implant removal - is it worth the unknown results?

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  If you have a silastic chin implant that was placed through a "submittal approach" as described below...the implant can easily be removed using the same incision in a few minutes under a local anesthetic.  When placed in this manner, there shouldn't be any chin ptosis however the chin will go back to its pre-operative weak projection.  A dermal filler can add forward projection to the chin.   If an intra-oral approach was used to place the chin implant, this cuts the superior muscle attachment which in my opinion can cause chin ptosis.  The implant is still best removed through a submental incision (under the chin) since this is the least invasive technique but some ptosis may result.  Chin ptosis is sagging of the chin muscle due to lack of bony support.  Dermal fillers can add forward projection but not " bone like support" to upwardly rotate the ptotic muscle.  In the end, you may require a chin tuck to reduce the ptosis followed by dermal fillers to add forward projection.  You have a third option, which is remove and replace the silastic chin implant (if the chin implant isn't in its proper location currently).  This option corrects the weak chin and any chin ptosis that would have resulted from simply removing the implant.  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".  The 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.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  Hope this helps.
