Do many doctors perform sliding genioplasty under twilight/IV sedation? (Photo)

I’d like to avoid general anesthesia if possible, and am wondering if it is safe and common to perform a sliding/osseous genioplasty without general anesthesia. I’ve had wisdom teeth removal in the past and feel okay with IV sedation, but know that sliding genioplasty is more serious and twilight sedation may not be suitable for it. I’ve also considered a chin implant, but think sliding genioplasty may provide a better and more stable result. Any insight into what’s possible would really help!
