1990年以来我院共收治10例外伤致眶下壁骨折,眶内容及下直肌嵌顿于骨折间隙并脱出于上颌窦,行眶骨折复位术治愈,报告如下:10例中男9例,女1例.右眼6例,左眼4例.均以眼部外伤后复视为主诉就诊.检查:右眼球下转受限,向外下方注视时偏斜度最大.牵引试验阳性.表麻下用镊子夹住近角膜缘结膜向眼球偏斜相反方向牵拉时有较强的抵抗力.X检查:右眼眶下壁有骨折线.CT扫描;确认骨折程度及部位.上颌窦上壁为基底,从眶下壁骨折间隙脱出,眶脂肪及下直肌呈团块状2×1×1cm大小高密度阴影出现.复视检查:复像垂直性分离,右外下方位分离度最大,远端的影像是红色(右眼戴红镜).诊断:右眼眶下壁骨折.
Since 1990, our hospital treated a total of 10 cases of trauma caused by suborbital fractures, orbital content and lower rectus implants in the fracture space and prolapse in the maxillary sinus, orbital fracture reduction was cured, the report is as follows: 10 cases of 9 males, Female 1. cases of right eye in 6 cases, 4 cases of left eye, both with ocular trauma diplopia as the main complaint treatment.Check: the right eye ball transfer limited, the highest downward skewed when skewed traction test was positive. Under the anesthesia with tweezers to clamp the proximal limbal conjunctiva to the eye in the opposite direction when the deflection is strong resistance.X examination: the right eye orbital wall fractured line.CT scan to confirm the fracture degree and site.maxillary sinus wall As the base, from the fracture wall of the infraorbital wall prolapse, orbital fat and lower rectus muscle showed a mass of 2 × 1 × 1cm size of high-density shadow appear.Patiental examination: the vertical separation of polygons, the largest right lower outer position resolution, The distal image is red (right eye wearing red mirror). Diagnosis: Right orbital wall fracture.
