I originally had a receding chin, so I had surgery to get my chin protruded, but after about 7 years, it became elongated, like a pear or a witch's chin, and my philtrum is also about 2cm long, so I had surgery to reduce my philtrum by 4mm and my chin by 5mm, but my chin looks too short on my face. My chin is already small, so it looks too short... Is 5mm usually a lot? I can cut the long ones, but there's no way to fix a short, stubby impression... What if I did something wrong...
