摘要目的 探讨整复眶底骨折不同手术入路的临床选择方法。方法 37例爆裂性眶底骨折根据骨折部位分为3组,分别采用下睑睫毛下入路(13例)、上颌窭入路(17例)以及联合手术入路(7例)进行手术,观察眼球突出度、眼球运动障碍、被动牵拉试验结果以及复视情况,并进行手术前后对比。结果 术前3组患者均有垂直复视和眼球运动障碍,眼球被动牵拉试验阳性(牵拉眼球向上遏阻力),双眼眼球突出度相差＞4 mm者29例,相差在2～4mm者8例。术后3组患者的双眼眼球突出度相差均在2mm以内,眼球被动牵拉试验阴性。下睑睫毛下入路组的全部13例和上颌窦入路组17例中的12例,眼球运动恢复正常,复视消失。上颌窦入路组中5例和联合手术入路组的全部7例,术后仍有眼球下转受限,向下方注视时复视仍存在。结论 对于需要手术整复的爆裂性眶底骨折,根据骨折部位,临床选择不同的手术入路可取得良好疗效。

abstractsObjective To study the clinical choice of surgical approach in the treatment of orbital floor fracture. Methods 37 patients with orbital floor fracture were divided into 3 groups by the site of fracture and received 3 surgical approach include incision under the eyelashes ( 13 case) ,through the maxillary sinus ( 17 cases) ,or both two surgical approach (7 cases). To compare the degree of proptosis,ocular motility forced retraction test,diplopia before and after surgery. Results 37 patients had vertical diplopia, abnormal eye vertical movement, positive forced retration test ( to pull the eye upword with resistance), and the difference in degree of proptosis more than 4mm in 29 case,2 -4mm in 8 cases before surgery. After the surgery,all the patients had negtive forced retraction test ( to pull the eye upword with no resistance)and less than 2mm in the difference of proptosis' degree. All 13 cases in incision under the eyelashes group and 12 cases in through the maxillary sinus grpup recovered in eye movement and diplopia. 5 cases in through the maxillary sinus group and all 7 cases in the joint surgery group had underaction of ocular movement and diplopia on downgaze. Conclusion To choice different surgical approach in the treatment of orbital floor fracture,good healing effect could be available.
