This descriptive analytical study evaluated the cause, type, incidence, demographic, and treatment data of zygomatico-orbital complex and zygomatic arch fractures managed at our program during a 5-year period.
A total of 1,857 charts of patients presenting maxillofacial trauma and treated by the Division of Oral and Maxillofacial Surgery, from the Piracicaba Dental School (UNICAMP), were reviewed. A total of 371 patients presented with zygomatico-orbital complex and/or zygomatic arch fractures. Patients with isolated orbital fractures were excluded. The patients ranged in age from 2 to 88 years. Epidemiological data including age, gender, etiology, site of injury, and details of treatment were collected and tabulated in Excel software (Microsoft). All maxillofacial injuries were assessed and treated by residents and staff surgeons. Other concomitant bodily injuries were treated by pertinent consulting specialists.
The majority of fractures were sustained by males between 21 and 40 years old, usually resulting from falls, altercations, and bicycle accidents. Unilateral fractures of zygomatico-orbital complex were present in 266 patients (71.69%). Bilateral fractures were found in 22 cases (5.93%). Unilateral zygomatic arch fractures occurred in 39 cases (10.51%). A total of 210 patients (56.60%) did not receive surgical treatment. Surgical intervention was done in 161 patients (43.40%). The surgical treatment was conducted using the approach as reported by Ellis and Kittidumkerng in 1996. A complication incidence of 6.47% was observed, which is compatible with related articles in the literature.
The study revealed interesting features about etiology, demonstrated by the high occurrence of bicycle accidents. The treatment protocol proposed to the patients showed adequate results as evidenced by low complication frequency. The findings of this study bring information about an area in Sao Paulo State, Brazil, that is valuable in reaffirming previously established trends and identifying new patterns of disease frequency.
本描述性分析研究评估了在我们的项目中5年期间处理的颧眶复合体和颧弓骨折的病因、类型、发生率、人口统计学和治疗数据。
回顾了来自皮拉西卡巴牙科学院（UNICAMP）口腔颌面外科治疗的1857例颌面外伤患者的病历。共有371例患者出现颧眶复合体和/或颧弓骨折。排除单纯眶骨折患者。患者年龄从2岁到88岁不等。收集包括年龄、性别、病因、损伤部位和治疗细节等流行病学数据，并在Excel软件（微软）中制成表格。所有颌面损伤均由住院医师和外科 staff 进行评估和治疗。其他伴随的身体损伤由相关会诊专家治疗。
大多数骨折发生在21至40岁的男性，通常由跌倒、争吵和自行车事故引起。266例患者（71.69%）存在单侧颧眶复合体骨折。22例（5.93%）为双侧骨折。单侧颧弓骨折39例（10.51%）。共有210例患者（56.60%）未接受手术治疗。161例患者（43.40%）接受了手术干预。手术治疗采用1996年埃利斯和基蒂杜姆克恩报道的方法。观察到并发症发生率为6.47%，与文献中的相关文章一致。
该研究揭示了关于病因的有趣特征，自行车事故发生率高证明了这一点。向患者提出的治疗方案显示出了足够的效果，并发症发生率低证明了这一点。本研究的结果提供了关于巴西圣保罗州一个地区的信息，这对于重申先前确立的趋势和识别疾病频率的新模式具有重要价值。
