What is the best way to reduce the buffalo hump on my neck? (Photos)

Dear Resourceful280143,
it is hard to tell for sure without an examination. Based on your photos, it looks like you would benefit from liposuction. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

Liposuction is the best treatment for what you have. Make sure you see a board certified plastic surgeon who has been doing liposuction for some time and is experience dealing with unusual problems.
