Do I need a chin implant, fillers, botox, bichectomy or jaw surgery? (photo)

Thank you for this question.Mandibular augmentation helps to improve jaw line appearance, facial trauma and congenital defects among other things. There are also non surgical treatments ( fillers) that can last 12 to 24 months. Botox will only weaken the muscle, it will not add volume and it does not contour your facial structure.  I would seek a board certified plastic surgeon that you are comfortable with to evaluate and discuss options as well as your desired look.

You have mentioned 2 of the treatments that would improve the shape and balance of your face. Removal of the buccal fat pad (Bichectomy) would slim your face and a chin implant would give you a youthful and well defined chin and jawline. The procedures can be performed at the same time. 

Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  From the photos, your chin is quite weak.  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.  In my opinion, you are a good candidate for chin implant surgery.  
Hope this helps.
