Can Lower Jaw Surgery Be Reversed?

My lower jaw was moved forward 4mm and angled down. My surgeon did not tell me until afterwards that my jaw was going to be angled down as well. He sais I did not have a genioplasty but my chin is longer. He said I had an url between my chin and lower lip which he corrected. However we never discussed that in the consultation, is it normal for this to be corrected without informing the patient? Can my Jaw/Chin be repositioned to their pre surgery position? I am one year post op. Thank you
