Two patients developed exotropia with limited medial rectus function following endoscopic intranasal ethmoid sinus surgery. In both patients, fractures occurred in the medial orbital wall. The first patient required horizontal rectus muscle surgery to regain ocular alignment. The second required no surgery, but was left with limited horizontal motility secondary to scarring at the fracture site. While endoscopic techniques improve the surgeon's view of sinus anatomy, they do not eliminate the risk of entering the orbit and causing ocular complications.
两名患者在内镜下经鼻筛窦手术后出现外斜视，内直肌功能受限。两名患者均发生眶内侧壁骨折。第一名患者需要进行水平直肌手术以恢复眼位对准。第二名患者无需手术，但因骨折部位瘢痕形成而导致水平运动受限。虽然内镜技术改善了外科医生对鼻窦解剖结构的视野，但并不能消除进入眼眶并引起眼部并发症的风险。
