作者在本文中描述利用下颌骨联合作为骨移植修复眶底缺损是安全、可行的。 方法 患者16例,10例为分离性骨折,6例为眶底缺损伴有其他颌面骨折。眶底缺损直径小于2cm。 首先行眶底缺损探查,之后在局麻下从至切开唇前庭,完全暴露颏骨,包括两侧颏孔及颏骨下缘,依据眶底缺损大小,用702号组织钻于骨联合处切割所需移植骨,要注意钻头与骨面上端及远端呈45°,避免损伤前牙根,便于移植骨取出。然后用弯形小骨凿取
The authors describe the use of mandibular joint as a bone graft in the repair of orbital floor defects is safe and feasible. Methods 16 cases of patients, 10 cases of fractures, 6 cases of orbital floor defect accompanied by other maxillofacial fractures. Orbital defect diameter less than 2cm. First of all, orbital floor defect exploration, and then under local anesthesia from the incision lip vestibule, complete exposure of the chin bone, including both sides of the mental foramen and chin margin, according to the size of the orbital floor defects, Need to cut the bone graft, pay attention to the drill and the bone surface and the distal end was 45 °, to avoid damage to the anterior root, bone graft for easy removal. Then use a curved bone chisel to take
