Adaptable people: There are two main anatomical causes of sleep apnea – hypertrophy and relaxation of soft tissues and narrowing of bony structures. Soft tissue problems are mostly solved by surgery in the ENT line, and narrowing of bony structures is mostly solved by orthognathic surgery in the oral surgery. In patients with small jaws, the airway of the pharyngeal cavity is narrowed because the bone grows in a bad position. Even if the soft tissues are removed as much as possible, the airway will still be closed, so it is necessary to saw off the bone and then pull it outward, and then fix it with nails to artificially widen the airway. This type of orthognathic surgery includes mandibular advancement surgery and bimaxillary surgery where both the upper and lower jaws are changed. Orthognathic surgery is done at the same time as suspensory palatopharyngoplasty when necessary. Treatment Results: Orthognathic surgery is currently effective in treating sleep apnea. Surgical Risks: This is a major surgery, and the patient’s face will change after the surgery, such as widening of the face, jaw size; there are also some patients who have occlusal joint disorders, numbness of the face for a period of time after the surgery. Pain and Recovery: Surgery is relatively painful. The simplest jaw advancement surgery in orthognathic surgery is already considered a relatively minor surgery, and it takes about a month for patients to slowly recover, and the recovery time for double jaw surgery is even longer.
