The Okuro Facial Clinic Group performs many "back hamula procedures" that are less burdensome for patients.
Major cosmetic surgeons remove the fat and insert the fat taken from the thigh into the orbicularis retaining ligament, but there is no need to do that. However, this is not necessary, because the protruding fat can be inserted directly into the orbicularis retaining ligament to solve the problem. This is the surgical method known as the hamula method.
