摘要
目的探讨眶壁爆裂性骨折继发眼球内陷畸形的修复方法。方法1996年12月～2004年3月,共治疗眶壁爆裂性骨折继发眼球内陷患者56例,男30例,女26例。年龄22～48岁,平均32.5岁。受伤至手术时间16d～5年,合并复视患者34例,视力较受伤前降低者35例。采用下睑缘切口,于下眶缘骨膜下沿内下眶壁向眶尖方向潜行剥离。充分暴露骨折部位和松解嵌入上颌窦的眼眶组织并使其复位,使之成为骨膜下间隙。依据眼球的内陷程度,采用高密度多孔聚乙烯(poroushigh-densitypolyethylene,PHDPE)Medpor修复眶内下壁及其他眶壁缺损,矫正眼球内陷畸形。结果术后所有患者经2个月～5年随访,眼球内陷程度均稳定在2mm以内,无畸形复发及其他并发症发生。术后眼球内陷畸形均得到明显改善。34例复视患者中27例恢复,35例视力下降患者中9例视力较术前有不同程度改善,无复视加重和视力下降现象。大多数患者外观改善明显,其他患者也有不同程度改善,患者对手术效果满意。结论眶壁骨折整复术安全有效,手术应及早进行。Medpor组织相容性好、塑形容易、硬度适中、吸收率低、并发症少及手术效果稳定持久,是首选植入物。为防止眼球内陷畸形矫正不足,术中一般需矫正超过对侧1～2mm,严重的内陷者,术中矫正应超过2mm以上。
Objective To study the surgical reconstruction for correction of enophthalmos deformity caused by orbital blow-out fractures. Methods From December 1996 to March 2004, 56 cases of enophthalmos deformity caused by orbital blow-out fracture were repaired. There were 37 cases diplopia, 35 cases with worsened visual acuity than pre-trauma. Typical sub-ciliary incision was employed to expose the fractured area.The dissection was done beneath the medial and inferior obital periosteum. The fracture areas were exposed and the tissues protrusing to sinus maxillaries were released through the space between fractural bones. After the medial and inferior orbital walls and orbital floors were exposed,the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with Medpor which were fixed to the area beneath the periosteum with 2 plates at least. Results All 56 cases of enophthalmos deformity caused by orbital blow-out fracture repaired with this technique recovered well and their facial appearance improved greatly. With a follow-up ranged from 2 months to 5 years, the degree of enophthalmos stabilized at within 2 mm, no relapse and other complications occurred. Of 34 patients with diplopia, 27 were improved. Of the 35 cases with worsened visual acuity, 9 were improved with different degree. No diplopia or visual acuity worsening occurred. Conclusion It is safe and effective to correct the orbital blow-out fractures. The earlier it is repaired, the better the effect will be. Medpor with its advantages like better histocompatibility, easier sculpturing, moderate hardness, lower absorptivity, fewer complications and permanence effect is the preferable implantation material for correcting enophthalmos deformity.
