下颌骨喙突骨折约占面部骨折的0.6％～4.7％。Rapidis等对1789例颌面骨折的研究表明,喙突骨折占2.9％,并且全部伴发颧骨和其它面骨的骨折。 由于颧弓对其下方的下颌骨的屏障作用,单独的喙突骨折而不伴发颧弓骨折的情况非常罕见,而单独的双侧喙突骨折更未见文献报道。本文报道一例单独的双侧喙突骨折。 病例 一名30岁的女性患者,由于其丈夫用拳头殴打左边头部,致使其左面部疼痛,伴有张口严重受限。体检见左颞区触痛,张口疼痛,张口度仅5mm,双 Mandibular coracoid fractures account for about 0.6% to 4.7% of facial fractures. Rapidis and other studies of 1789 cases of maxillofacial fractures, the coracoid fractures accounted for 2.9%, and all accompanied by the fracture of the cheekbones and other facial bone. Due to the barrier function of the zygomatic arch to the underlying mandible, it is rare to have a single coracoid fracture without rupture of the zygomatic arch, whereas no separate bilateral coracoid fracture has been reported. This article reports a single bilateral coracoid fracture. Case A 30-year-old female patient suffered severe pain in the left side of her face with severe restriction of her mouth because her husband beat his left head with his fist.
