改良髁突摘除术在成人髁突囊内骨折治疗中的应用

Application of improved condylectomy in adult intracapsular fracture of mandibular condyle

目的:探讨改良髁突摘除术在成人髁突囊内骨折中的应用。方法 :对33例成人髁突囊内骨折给予髁突摘除术,术后辅以适当的颌间牵引及开口训练。结果:80%以上的患者6个月内恢复正常咬合关系,开口度达35 mm以上;所有患者均未发生永久性面瘫和关节强直。结论:改良髁突摘除术操作简单,适合在基层医院开展,但有严格的适应证,掌握好适应证是治疗成功的关键。

PURPOSE： To evaluate the application of improved eondylectomy in adult intracapsular fracture of mandibular condyle. METHODS： Thirty-three adult patients with intracapsular fracture of mandibular condyle were treated by improved condyleetomy, assisted by appropriate intermaxillary traction and mouth opening exercise after operation. RESULTS： More than 80% patients had normal occlusion, and the mouth opening reached over 35 mm 6 months after operation; no permanent facial nerve palsy and ankylosis were noted. CONCLUSIONS： Improved condylectomy is simple and fits in primary hospital, but has strict indication; appropriate selection of indication is the key to success.
