下颌骨髁状突颈部内弯骨折手术复位方法很多,但都是在分离下髁状突,在离体情况下将髁状突复位固定。作者介绍一种不分离髁状突行髁状突骨折复位内固定术,取得满意效果。 病例介绍 患者女性,44岁,临床表现为外伤后左耳屏前疼痛,张口受限,(牙合)关系错乱,下颌骨X线正侧位片显示左下颌骨髁状突颈部骨折,呈水平内弯。手术方法:左颌下切口,显露下颌骨升支到乙状切迹及骨折断端,可见到髁状突,但不能夹住使其复位。用骨锯从骨折断端垂直向下到下颌角纵形截开下颌骨升支,并取出升支后缘骨质,用钳子很容易伸入夹住髁状突,使
Mandibular condyle neck fracture surgery in many ways to reduce the surgical reduction, but are in the separation of the mandibular condyle, mandibular condyle in situ resetting fixation. The author describes a non-separation condyle condyle fracture reduction and internal fixation, and achieved satisfactory results. Case Description Female patients, aged 44, clinical manifestations of traumatic left ear on the screen before the pain, limited mouth opening, (occlusion) relationship disorders, mandibular X-ray films showed the left mandibular condyle neck fracture, was Bend horizontally. Surgical methods: the left submandibular incision, revealed the mandibular ascending branch to the sigmoid notch and broken ends, you can see the condyle, but can not be pinched to reset. Use the bone saw perpendicular to the broken ends of the fracture to the mandibular angle longitudinal trocar mandibular ascending trocar and remove the ascending posterior margin of the bone, with pliers is very easy to clasp the condyle, so that
