下颌骨喙突合并同侧颧弓骨折的改良手术治疗

目的：探讨下颌骨喙突合并同侧颧弓骨折安全有效的治疗方案。方法采用半侧冠状切口，在对颧弓骨折进行切开复位内固定手术的同时，对手术方式稍作改良，充分显露颧弓骨折区域后，将颧弓骨折块翻起，在其深面沿颞肌纤维走行方向向下继续分离寻找到喙突骨折块，并分离后摘除。结果手术切口一期愈合，随访3～24个月，开闭口，下颌运动功能正常。结论采用半冠状切口，治疗颧弓骨折的同时摘除下颌骨喙突骨折块，为手术治疗下颌骨喙突合并同侧颧弓骨折提出了一种新的并且安全有效的治疗方案。

An innovated surgical strategy of coronoid process fracture combined with ipsilateral zygomatic arch fracture

Objective To explore an effective and safe therapeutic strategy in the treatment of coronoid process fracture com‐bined with ipsilateral zygomatic arch fracture .Methods Through the semi coronoid scalp incision ,`an open reduction and internal fixation of zygomatic arch fracture was done .The operation was modified that the area of zygomatic arch fracture was exposed ade‐quately ,and then the fracture fragments of zygomatic arch were turned up .The coronoid process fracture pieces were isolated and removed along with the direction of muscle fibers in the temporalis muscle .Results All Cases of the surgical incisions were healed by primary intention .After 3 - 24 months following up ,the function of mouth opening and closing ,and the other movements of mandible became normal .Conclusion Through the semi coronoid scalp incision ,zygomatic arch fracture reduction and internal fixa‐tion and the coronoid process fracture pieces removing can be done simultaneously .In this way ,an effective and safe therapeutic strategy for treating coronoid process fracture combined with ipsilateral zygomatic arch fracture .
