鼻内镜鼻窦手术眼部并发症及其处理对策

摘要

目的 探讨鼻内镜鼻窦手术的眼部并发症可能的原因及处理经验,以期引起鼻内镜外科医生的重视.方法 收集作者收治的具有比较典型特征的鼻窦手术眼部并发症者22例8类.损伤类型分别为:纸样板损伤、眶内感染、额筛阻塞性囊肿、泪道损伤、眼外肌损伤、眶内出血、视神经损伤、眼底动脉栓塞等,并给予了相应处理.结果 单纯纸样板损伤9例中8例经保守治疗痊愈,眶纸样板损伤伴眶骨膜下感染1例和泪道损伤、额筛阻塞性囊肿各1例经鼻内镜手术痊愈.眼外肌损伤2例中1例经眼肌矫正术后除向健侧有轻微复视外,其他眼位无明显复视;另1例经眼肌矫正后仍有轻度复视.眶纸样板损伤致眶内出血1例痊愈,另1例眶内出血和1例眼底动脉栓塞导致的视力丧失无改善.视神经损伤6例(7侧)中1例(1侧)经视神经减压+眶尖减压视力恢复正常,另1侧及其余5例(5侧)无改善.结论 鼻内镜手术导致视神经损伤、眶内出血和眼底动脉栓塞导致的失明,治疗困难,预后极差;如果有残存视力,预后较好.%Objective To investigate the possible reasons and the treating expefiences of ophthalmic complications in order to elevate the attention of the nasal endoscopic surgeon.Methods This study was involved 8 categories in 22 cases which had typical characteristic of ophthalmic complications of endoscopic sinus surgery,including injury of lamina papyracea,obstructive cyst of frontal and ethmoid sinuses,orbital infection,injuries of lacrimal passages,injury of extraocular muscles,orbital hemorrhage,optic nerve injury and arterial embolism of optic fundi.The patients were given corresponding treatment.Results Injury of lamina papyracea Was cured by medical treatment while orbital infection,injury of lacrimal passages,obstructive cyst of frontal and ethmoid sinuses were completely recovered by endoscopic surgery.In one of the cases,the injured optic nerve had recovered after transnasal optic and orbital apex decompression but the other 6 sides of 6 patients had not been improved.In one case who had suffered from injury of extraocular muscles,their diplopia isappeared mostly.but the other cases had a slight diplopia after surgery.One case who had visual descending caused by orbital hemorrhage recovered.Two cases of visual loss caused by intraorbital hemorrhage and arterial embolism of optic fundi respectively were not improved. Conclusions It is very difficult to cure if the patients lose the sight because of optic nerve injury,orbital hemorrhage and the ischemia of orbit,however.if the patients had remnant vision the prognosis should be much better.
