It is better to choose a regular and reliable hospital for such an operation. The landlord can consult experts from Beijing and Likang Hospital. My colleague made mandibular angle in Beijing and Likang Hospital, and the effect was good. Now her face is much better than before, and her sisters are envious of her. If the landlord wants to do it, you can consult their experts first, let them look at your situation and give you the most reasonable method. hope this helps
