[ID Hospital] Double Hubei Surgery

1. What is double jaw surgery

The domestic medical name of double Hubei surgery isorthognathic surgeryThrough minimally invasive incisions in the oral cavity, the maxilla and mandible are simultaneously subjected to osteotomy, displacement, and titanium nailing and titanium plate fixation to correct maxillofacial deformities from the skeletal roots. It can not only restore normal chewing, biting, breathing, pronunciation and other oral functions, but also optimize the ratio of three courts and five eyes, and reshape smooth and exquisite side face lines. It is a fourth-level maxillofacial surgery with two-way improvement in function + aesthetics.

2. People suitable for double jaw surgery (core indications)

1. Bony ground (mandibular protrusion): The lower teeth wrap the upper teeth, the side face has a concave moon face, weak chewing, and the bite is misplaced
2. Bone convex mouth/buckteeth: The upper and lower mandible protrudes forward, the lips cannot be closed naturally, the gums are exposed from the smile (grinning), and the mouth is abrupt
3. Lower jaw retraction (small chin): The chin is short and retracted, and the side face has no jaw line, which is often accompanied by snoring and poor breathing
4. Facial asymmetry (partial jaw): The left and right faces are of different sizes, the chin is skewed, and the bite plane is tilted
5. bony open jaw: The upper and lower teeth cannot be closed normally, speaking leaks, and having difficulty eating and chewing
6. Long face/horse face deformity: The face, middle and middle court are too long, and the proportion of five senses is unbalanced

Note: Dental irregularities only require orthodontic correction, and only bone development dislocation requires double jaw osteotomy for improvement.

3. Core surgical procedures

1. Maxillary LeFort I osteotomy: The maxilla can be retracted, lifted and moved forward as a whole to improve convex mouth, gingival smile, and depression in the face
2. BSSRO sagittal split osteotomy of mandible: Adjust the front and rear position of the mandible, correct the ground cover, the lower jaw retraction, and the jaw skew
3. Genioplasty (optional): Simultaneously perform chin osteotomy and shaping to optimize the length and width of the chin to make the maxillofacial connection more natural and smooth
