To describe the radiological signs and demographic characteristics of patients who suffered facial trauma in South-East Asia.
This is a retrospective cross-sectional study of a 399 patients who presented with facial trauma over a 2-year period in a tertiary referral centre in South-East Asia. Patients with available CT scan films were included. Demographics, bony and soft tissue radiology characteristics were analyzed.
Male to female ratio was 320 (80%):79 (20%). Most of the facial trauma was due to Road Traffic Accident. Of 399 patients, 273 (68%) showed radiological signs of bone or soft tissue trauma. Of these 273 patients, left to right side involvement was 114 (41.7%) / 82 (30.03%), and 77 (28.2%) had bilateral involvement. Floor was the most involved wall (229[83.8%]) and the most involved rim was the inferior rim (164[60.07%]). There were 39 (14.2%) patients with blowout fracture. Bony nasolacrimal duct was broken in 56 (20.5%) patients. Optic canal fracture was found in 7 (2.5%) patients and it was associated with roof and superior rim fracture (P-values were 0.016, 0.046, respectively). Thirty-three (12.08%) patients had radiological signs of extraocular muscle involvement. Traumatic intracranial signs were associated with roof and superior rim fractures (P < 0.001 for both).
Floor and inferior rim were the most affected orbital structures in facial trauma. We described radiological risk factors association with optic canal, NLD fracture and intracranial involvement. We described extraocular muscle morphological signs, which could alert to the possibility of orbital floor fracture in equivocal cases.
描述东南亚面部创伤患者的放射学征象及人口统计学特征。
这是一项对东南亚一家三级转诊中心在两年期间收治的399例面部创伤患者进行的回顾性横断面研究。纳入有可用CT扫描片的患者。分析人口统计学、骨骼和软组织放射学特征。
男女比例为320（80%）：79（20%）。大多数面部创伤是由道路交通事故所致。在399例患者中，273例（68%）显示有骨骼或软组织创伤的放射学征象。在这273例患者中，左侧受累114例（41.7%），右侧受累82例（30.03%），双侧受累者77例（28.2%）。眶底是受累最严重的壁（229例[83.8%]），受累最严重的眶缘是下缘（164例[60.07%]）。有39例（14.2%）患者发生爆裂性骨折。56例（20.5%）患者的骨性鼻泪管断裂。7例（2.5%）患者发现视神经管骨折，且与眶顶和眶上缘骨折相关（P值分别为0.016、0.046）。33例（12.08%）患者有眼外肌受累的放射学征象。创伤性颅内征象与眶顶和眶上缘骨折相关（两者P均<0.001）。
眶底和眶下缘是面部创伤中最易受累的眼眶结构。我们描述了与视神经管、鼻泪管骨折及颅内受累相关的放射学危险因素。我们描述了眼外肌形态学征象，这在不明确的病例中可提示眶底骨折的可能性。
