It’s been 5 years since my osteotomy surgery for a retruded chin...

My chin length wasn’t short... It was a surgery where they performed an osteotomy and pulled it forward. But my chin became so much longer than before... My face became so long. Before, I had never once been told my face was long... The important thing is. When I smile, the tip of my chin bunches up and bulges. So my smile looks severely unnatural, and from the side I look like I have a protruding jaw... So I’m having revision surgery next month. Until now I kept going back and forth to the clinic for consultations. They told me to wait, so I waited. Only after a little over 5 years did I decide on revision surgery. Surgery... I’m really scared. I have to go alone and get the revision surgery. My heart is really pounding like crazy. My chin length became longer. And because the boundary of the osteotomy site feels bumpy... they say that if they naturally shave down from the osteotomy site, they can also reduce the chin length... and that they’ll do the revision with that method... But regarding the bulging bunching at the tip of my chin when I smile, the doctor doesn’t say anything. Even though I asked several times. It seems like he doesn’t know why. So I’m even more afraid of the revision surgery. The clinic where I had surgery was in Apgujeong, and I had it done by a director who is quite well known on broadcasts as a facial contouring specialist, but still. Is there anyone who had a case like mine? Every day I only dream about revision surgery failing and ruining me... or not waking up from anesthesia. I’m so scared I could die. Please... this time it has to succeed... I heard they usually don’t shave the very tip of the chin much... They usually adjust the length by doing an osteotomy around the middle. When I think about that, directly shaving the chin tip must be risky, so instead they do surgery that cuts the middle with an osteotomy... Would it be okay for me to have surgery that directly refines the tip of my chin?
