The author has made clinical studies on treatment of fractures of the zygomatic bone in terms of frequency of fractures according to sex, age, fracture type, main manifestations and treatment methods from 106 patients with zygomatic bone fractures among 969 patients with maxillofacial bone fractures. The results obtained were as follow: 1. The frequency of malar bone fracture was 4 times more in male than that in female. 2. The most prevalent age of malar bone fracture was 21-30 years of age, and the nexts were followed 11-20, 31-40, 0-10, 41-50, 51-60, 61-70, and over 71 in the orders. 3. Among maxillofacial bone fractures, mandibular fracture was most prevalent as 76.3%, and the nexts were followed by the maxilla (10.8%), the molar bone (9.7%) and the nasal bone (3.3%). 4. Among 106 fractures of the malar bone, zygomatic bone fracture only was occupied 48.1%, but the rests were accomplished by another maxillofacial bone fractures. 5. In classification of molar bone fractures according to Knight and North's, group 3 fractures were most prevalent, and followed by group 2, 1, 4 and 6 in the orders. 6. Main manifestations were upper cheek flattening, lower eyelid ptosis, subconjunctival ecchymosis, epistaxis, difficulty of mouth opening, pain during mouth opening and others in the orders. 7. 93.4% of malar bone fracture has been treated surgically, but the rests treated conservatively, and [symbol: see text] shaped elastic stapler wire has been effectively used to get fixation at zygomatico-maxillary fractures.
作者对969例颌面部骨折患者中的106例颧骨骨折患者，就骨折发生频率，按性别、年龄、骨折类型、主要表现及治疗方法进行了临床研究。所得结果如下：1. 颧骨骨折男性发生率比女性高4倍。2. 颧骨骨折最常见的年龄为21 - 30岁，其次依次为11 - 20岁、31 - 40岁、0 - 10岁、41 - 50岁、51 - 60岁、61 - 70岁及71岁以上。3. 在颌面部骨折中，下颌骨骨折最为常见，占76.3%，其次依次为上颌骨（10.8%）、颧骨（9.7%）和鼻骨（3.3%）。4. 在106例颧骨骨折中，单纯颧骨骨折占48.1%，其余合并有其他颌面部骨折。5. 根据奈特（Knight）和诺思（North）对颧骨骨折的分类，3型骨折最为常见，其次依次为2型、1型、4型和6型。6. 主要表现依次为面颊上部扁平、下睑下垂、结膜下瘀斑、鼻出血、张口困难、张口时疼痛等。7. 93.4%的颧骨骨折采用手术治疗，其余采用保守治疗，[符号：见原文]形弹性加压钢丝已有效地用于颧骨 - 上颌骨骨折的固定。
