Most cosmetic rhinoplasty involves removal of a dorsal hump. This means the surgeon will cut, rasp, or remove the hump, leaving a flattened surface beneath the nasal skin. Unfortunately this widened flat surface (called an "open-roof" or book-spine deformity) often looks as bad as the previous bump or hump!The nasal bones that make up the sides of this open roof deformity can be brought together to restore the nasal pyramid shape by first "breaking" the bones so they can be narrowed. I suspect patients imagine the surgeon teeing off with a sort of club and whacking the nose to break it, or hitting the nose with a mallet!This does NOT happen.Instead, a tiny, sharp instrument with an edge guard called an osteotome is used to put a thin cut in the eggshell-thin nasal bones. The osteotome is tapped lightly with a surgical mallet, and then the bones, once freed from their bases by the osteotomies, are gently clicked together in the middle, "closing" the open roof and restoring the nice pyramidal shape.This is not painful since you are asleep, and the bones are splinted to hold them in their new desired position post-op. Pain is not so bad at all (my own daughter used only Tylenol when I did her rhinoplasty with bone breaking at age 15! Look at my photo and you can see why she wanted "dad's nose" made smaller!) I suspect you will have as much pain with bones broken as you would if they were not. Also, no difference with open vs. closed as far as pain goes. You may have bruising from the bone edges, but then again, you may have bruising from rhinoplasty anyway without bony work.It's NOT "extra" pain, but trying to avoid breaking the nasal bones when this is a necessary part of the cosmetic improvements is a huge mistake that I occasionally see from other doctors. Don't let this happen to you by expressing fear of a usual part of the procedure (if done properly)! Best wishes! Dr. Tholen
