A case of visual loss following cranio-maxillofacial trauma is reported. The patient had a sudden partial blindness associated with a fracture of the roof, medial and lateral orbital walls. Access to the orbit was achieved through a transethmoidal approach using the Howarth-Lynch medial incision and resecting the bone fragments which impinged on the optic nerve. The patient had total return of visual acuity, without surgical complications. The role of orbital and optic decompression in the management of patients with traumatic optic neuropathy is discussed. Its indications are controversial and the procedure should be considered only within the context of the specific needs of the individual patient.
报告了一例颅颌面创伤后视力丧失的病例。患者突然出现部分失明，伴有眶顶、眶内侧壁和外侧壁骨折。通过使用霍华斯-林奇内侧切口经筛窦入路进入眼眶，切除压迫视神经的骨碎片。患者视力完全恢复，无手术并发症。讨论了眼眶减压和视神经减压在创伤性视神经病变患者治疗中的作用。其适应症存在争议，该手术应仅根据个体患者的具体需求来考虑。
