Is the thickness of silicone implants determined for each height? So, if you put 4mm in, everyone will have the same nose shape?? I’m curious.

It's been a little over a month since I had plastic surgery, and I'm curious about the thickness of the implant. I wonder if silicone has a nice shape. When I asked the director of the hospital where I worked, he said that the one in Zeco is 4mm high and 9.5mm thick. He said the thickness is fixed. 3mm in height is the thickness. You say it's about 9mm. So what I'm curious about here is, isn't it possible to cut the thickness of the implant and put it in thinner? The reason I'm asking this is because before the surgery, I kept emphasizing that the bridge of my nose was thin and my nasal bone was thin, so I predicted that if a thick implant was put in, I would end up with a protruding nose, with a silicone shade and a prominent silicone shape. My attitude has always been to emphasize a thin, gentle and natural look, but now, after a month and a half, it looks too thick. I'm really curious about the thickness of the silicone. If you look at it this way, does everyone who had surgery with 4mm silicone get implants of the same thickness? Or do you cut the thickness of the silicone implant to match the bone thickness of the person? I'm assuming that at one hospital, the thickness of the implant is determined for each height without doing anything like that. I'm really curious! I also heard that other hospitals are making the thickness thinner. I wonder if they reduce the thickness by lowering the height, or do they keep the height the same and only shave off the thickness? I don't know if I'm doing it, what is it?
