高壓氣體引起的創傷性眼眶氣腫

Traumatic Orbital Emphysema from Compressed Air Injury

摘要


一位17歲男性病人遭空氣槍誤擊右眼,造成右側額下部及右眼上下眼瞼明顯皮下氣腫,右眼內側結膜有一2mm裂傷,結膜下腔360度充滿空氣。視力下降至20/40。電腦斷層顯示無眼眶骨折,但除了右側額部及上下眼瞼皮下氣腫外,眼窩腔及眼球後方亦有空氣存在。病人視力於兩天內恢復,在受傷後第五天,眼瞼之皮下氣腫完全消除,僅剩些許結膜下微氣泡。

A 17-year-old boy sustained right ocular injury by airgun in an accident. A 2mm conjunctival laceration was produced in the nasal inferior fornix, which acted as a portal of entry for air into the sub-conjunctival, subcutaneous and retrobulbar space. Visual acuity was reduced to 20/40. Computed tomography revealed no evidence of orbital fracture but showed severe subcutaneous emphysema in the right frontal region and eyelid, and orbital emphysema with retrobulbar space involved. The visual acuity returned to 20/20 within 2 days. Five days after trauma, the subcutaneous emphysema was completely resolved and little subconjunctival emphysema was found.
