What changes can be expected after jaw correction surgery?

I have a question for those considering jaw correction surgery. I have many questions regarding the changes after the operation. I would like to know what changes might occur in the shape of the jaw or facial contours, as well as how people around me might react. I need valuable advice from those with experience regarding pain management and aftercare methods. I am also curious about the time it takes to return to daily life, so I would be grateful if you could share any personal experiences or tips.
