Chin implant or sliding genioplasty for Asian male?

Thank you  for your pictures.  In my opinion you would be a good candidate for either a sliding genioplasty or a chin implant.  The genioplasty uses your own bone to enhance your chin but there is more swelling and discomfort.  The genioplasty incision is well hidden because it is inside the mouth.  The chin implant has a bit less swelling and less discomfort. 

Your chin is short both horizontally and vertically. For this reason I would lean towards a sliding genioplasty as it is best suit7ed to correct both deficient chin dimensions. With your chin augmentation, regardless of which method you use to do it, you should also consider jaw angle implants. As the chin achieves more projection your jaw angles will look even higher and weaker and your jawline will be imbalanced. 

 A Chin implant can be performed under local anesthesia as an outpatient procedure. A sliding genioplasty is performed under general anesthesia as an inpatient procedure in the hospital with at least one overnight stay. Chin implants are manufactured in a variety of sizes and shapes,  are composed of Silastic, and are inserted through a submental approach. For many examples, please see the video and the link below

 A chin implant will do the job.  Viewing your photos, it shows a weak chin.  A chin implant will project the chin forward to better balance the lower half of the face.  In addition, since you mentioned 'jawline', I suggest some Radiesse in the mandibular angle (angle of the jaw) to give you more angularity.

Chin implant would be appropriate.  I am one of those opposed to sliding genioplasty for ordinary "weak" chins. I think it is overkill and unnecessary surgery.An implant is simple, reversable and the scar is in your mouth recovery is quick, prices are less than genioplasty. No keloids form in the mouth.Prices vary surgeon to surgeon and geographically. Call up an experienced Board Certified Plastic Surgeon and speak to the office manager for price ranges.

The genioplasty would be a benefit to you. A sliding genioplasty would lengthen the area under the chin better and flatten it more appropriately. It is an intraoral procedure, so no keloid issue. The implant could work but be less effective; although less costly. Again, ask the surgeon to do it from inside the mouth avoiding a skin incision
