To evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to Taleghani hospital, Tehran, Iran.
This cross-sectional study was conducted during a 2-year period from 2014 to 2012 in Taleghani hospital of Tehran. We included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. The demographic information, type of fracture, location of fracture and nerve injuries were assessed and recorded in each patients. The frequency of sensorimotor injuries in these patients was recorded. Data are presented as frequencies and proportions as appropriate.
Overall we included 495 patients with maxillofacial trauma with mean age of 31.5±13.8 years. There were 430 (86.9% men and in 65 (13.1%) women among the patients. The frequency of nerve injuries was 67.7% (336 patients). The mean age of the patients with nerve injuries was 33.4 ± 3.7 years. Marginal mandibular branch of facial nerve was the most common involved nerve being involved in 5 patients (1%). Regarding trigeminal nerve, the inferior alveolar branch (194 patients 39.1%) was the most common involved branch followed by infraorbital branch (135 patients 27.2%). Mandibular fracture was the most common injured bone being reported in 376 patient (75.9%) patients followed by zygomatic bone in 100 patient (20%).
The most frequent fracture occurred in mandible followed by zygoma and the most injured nerve was inferior alveolar nerve followed by infraorbital branch of trigeminal nerve. In facial nerve the marginal branch was the most involved nerve. The frequency of nerve injury and the male to female ratio was higher in the current study compared to the literature.
评估转诊至伊朗德黑兰塔莱加尼医院的颌面部创伤患者的感觉运动神经损伤情况。
本横断面研究于2012年至2014年在德黑兰塔莱加尼医院进行了为期2年的时间。我们纳入了研究期间转诊至我们中心的总共495例颌面部创伤患者。评估并记录了每位患者的人口统计学信息、骨折类型、骨折部位和神经损伤情况。记录了这些患者中感觉运动损伤的频率。数据以适当的频率和比例呈现。
总体而言，我们纳入了495例颌面部创伤患者，平均年龄为31.5±13.8岁。患者中有430例（86.9%）为男性，65例（13.1%）为女性。神经损伤的频率为67.7%（336例患者）。神经损伤患者的平均年龄为33.4±3.7岁。面神经下颌缘支是最常受累的神经，有5例患者（1%）受累。关于三叉神经，下牙槽支（194例患者，39.1%）是最常受累的分支，其次是眶下支（135例患者，27.2%）。下颌骨骨折是最常见的受伤骨骼，有376例患者（75.9%）报告，其次是颧骨骨折，有100例患者（20%）。
最常见的骨折发生在下颌骨，其次是颧骨，最易受伤的神经是下牙槽神经，其次是三叉神经的眶下支。在面神经中，下颌缘支是最常受累的神经。与文献相比，本研究中神经损伤的频率和男女比例更高。
