Orbital emphysema is a frequent condition associated with medial wall fractures after blunt trauma. It is usually a benign, self-limited phenomenon. The authors are unaware of previous reports of severe orbital emphysema needing emergency decompression with no evidence of any previous significant trauma such as the case presented herein.
METHODS/RESULTS: A 51-year-old woman had painful swelling of the left orbital region that prevented her from opening her eyelids. She complained of a coincident cold with abundant mucous rhinorrhea. She had blown her nose vigorously several times. A computed tomography scan revealed a left proptosis, an extensive orbitopalpebral emphysema, and a blowout fracture of the medial wall of the left orbit. A complete ophthalmic examination was only possible after a needle decompression. No significant ocular damage was observed, so outpatient treatment was provided. Twenty-eight hours later, the swelling had almost disappeared, and the ocular assessment was normal.
A forceful expiratory effort raising intranasal pressure may cause a medial wall orbital fracture. If the airway hyperpressure episodes are repeated, a severe orbitopalpebral emphysema may develop. Should there be any suspicion of vascular compression, it must be drained to allow the assessment of visual function and theoretically prevent a potentially irreversible ischemic visual loss.
眼眶气肿是钝性外伤后内侧壁骨折常见的伴随情况。它通常是一种良性的、自限性现象。作者未发现此前有关于严重眼眶气肿需要紧急减压且无任何如本文所述既往重大外伤证据的报道。
方法/结果:一名51岁女性左侧眼眶区域疼痛肿胀,导致她无法睁开眼睑。她主诉同时患有感冒且伴有大量鼻黏液溢。她用力擤鼻数次。计算机断层扫描显示左侧眼球突出、广泛的眶睑部气肿以及左侧眼眶内侧壁爆裂性骨折。仅在进行针吸减压后才得以进行全面的眼科检查。未观察到明显的眼部损伤,因此给予门诊治疗。28小时后,肿胀几乎消失,眼部评估正常。
用力呼气使鼻内压升高可能导致眼眶内侧壁骨折。如果反复出现气道高压发作,可能会发展为严重的眶睑部气肿。如果怀疑有血管受压,必须进行引流,以便评估视功能,并从理论上防止潜在的不可逆性缺血性视力丧失。
