Bone flap is a medical term, which refers to a small bone piece that can be taken out or extracted by surgery. These bone fragments may come from any part of the human body and are usually used in plastic surgery, such as nose plastic surgery or skull defect repair. Bone flap can provide needed bone material to support the defect area and promote growth and healing.

In addition to plastic surgery, bone flap is also commonly used in oral and dental surgery. For example, when a patient needs a tooth transplant, a bone flap can be used to fill the necessary bone mass. Bone flap can also be used to support alveolar bone and promote better growth and healing. In addition, bone flap can also be used for fracture repair and joint replacement surgery.

Bone flap surgery is usually performed by professional plastic surgeons or dentists. Surgery may require a certain recovery period to ensure that patients can heal normally. After bone flap surgery, patients need to pay close attention to postoperative care and follow the doctor's advice to ensure the best recovery effect. Although bone flap surgery may cause some discomfort and complications, it can also provide an effective bone replacement scheme, which will enable many patients to obtain better medical effects and quality of life.
