Do I need a jaw surgery? Or lower braces will work? Is my jaw the problem? Or just the protruding teeth? (photos)

Ive been with a couple of orthodontists hetr in my country and they all have different opinions. Headgear plus braces, TMJ appliance plus braces, and the other said the lower brace can fix it. I dont know what to believe in. I have lower braces now since I only have a few upper tooth left. Please help me. Im afraid to undergo the jaw surgery since I have a acidic stomach problem so if I cant eat, my stomach will get worse. Thank you for the response.
