안와 파열 골절의 임상적 연구

Abstract

Purpose: The incidence rate of blow-out fractures are increasing in number due to traffic accidents, violence, industrial disasters especially in young men patients. There are some reports of diagnosis and treatment of this fracture, but detailed and large data provided in overall aspects are rare. We analysed large series data to provide treatment guide lines of the blow-out fractures.

Methods: The author reviewed retrospectively 1050 blow-out fracture patients who had been followed up at least 6 months from January 2008 to June 2013. Medical hospital records were reviewed according to cause, site of fracture, symptoms, associated fractures, operative methods, postoperative complications, etc.

Results: In 1050 patients, 809 patients were male, 241 patients were female. The ratio of male to female was 7: 3. Mean age was 32.2 years and blow-out fractures were most often seen in the 21-30 age group. The outbreaking time were June and Sunday and the most common cause of these fractures were traffic accidents. The most common fracture site was inferior wall(58%) followed by medial wall(21%) and both inferior and medial wall. The highest associated facial bone fractures was nasal bone(25%). Orbit wall reconstructions were done in the 1018(97%) patients and time interval between accidents and operation was mostly within 2 weeks. Surgery was conducted within 2 weeks after injury and inserted material was used all of these patients. For these orbital reconstructions, Floor liner®(50%) was mainly used, following by Mesh plate(27%), and Medpor®(23%). There were remained ocular complications such as dipolia(18%), gaze limitation(1.6%), enophthalmos(0.9%), retrobulbar hematoma(0.2%) in 41 patiens.

Conclusion: We surveyed extensive data of blow-out fractures and this data will provide helpful information of diagnosis and therapeutic plans of the these fractures.
