Abstract：
Objective:To explore the indications , surgery method and effect for the treatment of medial rectus muscle entrapment with endoscopic surgery.Method: Eight medial rectus muscle entrapment patients were enrolled in this study,3 cases underwent obital medial wall fracture reposition and medial rectus muscle adhesion decomposition surgery through endonasal endoscope,and 5 cases received obital medial wall fracture reposition surgery with endoscope through nasal cavity and lacrimal caruncle conjunctival incision. Result:The diplopia disappeared and eyeball abduction function recovered in 6 cases of medial rectus muscle entrapment patients within 2 months,and 1 case with each surgery had mild diplopia and eyeball incomplete abduction left.Conclusion:Adopting endonasal endoscopic surgery or dual approaches surgery with endonasal endoscopic and transcaruncular surgery were ideal methods for medial rectus muscle entrapment diseases.Surgery with endoscope has the characteristics of clear field and less damage.The surgery should be performed whithin 3 weeks, and the entrapment of medial rectus muscle can be resoved effectively.
摘要：
目的:探讨适应证,内镜手术治疗内直肌卡压的手术方法和效果。方法:纳入8例内侧直肌卡压患者,3例患者经鼻内镜行骨内侧壁骨折复位及内直肌粘连分解术,5例患者经鼻腔和泪腺棘结膜切口行内镜下骨内侧壁骨折复位术。结果:6例内侧直肌卡压患者复视消失,眼球外展功能在2个月内恢复,每次手术1例出现轻度复视和眼球不完全外展。结论：采用经鼻内镜手术或双入路手术联合经鼻内镜和经胸手术是治疗内侧直肌卡压的理想方法。内窥镜手术具有视野清晰、损伤小的特点。手术应该在3周内进行，可以有效地改善内侧直肌的压迫。
