Is the muscle bulge on the right side & slight paralysis on left side of chin permanent & if not, can it be fixed? (Photos)

we would need to see preop smiling pictures to make sure that the skin fold you see is really new. What kind of implant is it and how was it placed/   In any event it's too early and you need to leave things alone for a while. So, send picture smiling and non smiling from before surgery and after.

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over the 30 years.  Non smiling photos of your lower face from the front and side would help in ethics's evaluation as well as some basic information regarding the chin implant, original surgery and the revision.  What material is the chin implant made from, shape, size and what approach was used in both surgeries?  In other words was the implant placed through the moth or a small incision under the chin? 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.  
  It's not uncommon to have slight restriction in moving the mouth, in particularly the lower lip following chin implant placement.  The intra-oral approach increases this as it has far more tissue dissection.  This is why I use a small, curved incision under the chin for chin implant placement.  The chin implant is placed (I believe it should be) below the chin muscle (Mentalis) and the covering of the bone.  The restriction, of lower lip movement, is due to the muscle accommodating the added volume and projection provided by the implant.  The movements typically return to normal in several weeks.  At 5 weeks you might still get an improvement in the numbness (mental nerve is the sensory nerve that's involved) and the weak left lower lip (marginal mandibular nerve...a branch of the facial nerve which is a motor nerve).  Neither of these nerves can be repaired if significantly injured and while some cross sensory innervation could decrease the numbness, there is no cross motor nerve innervation to depress or pull down the lower lip if the nerve is injured.  It will either heal or remain weak on its own.Hope this helps
