表面麻醉下经球结膜手术治疗原发性结膜下眶脂肪脱垂

目的：评价表面麻醉下经球结膜手术治疗原发性结膜下眶脂肪脱垂的临床疗效。
　　方法：选择2011-01/2015-06在我院眼科进行原发性结膜下眶脂肪脱垂手术治疗的患者11例22眼,记录主观和客观手术时长、术中配合情况、术后恢复及复发情况及并发症。
　　结果：患者17眼的麻醉效果明显,5眼(均为第二术眼)在补点1次表面麻醉药后疼痛消失,22眼均能顺利完成手术操作。术中配合程度Ⅰ级组和Ⅱ级组的客观手术时长相比,差异具有统计学意义(t=-3.123,P<0.01),提示手术中配合程度越差的患者其客观手术时间比较长。术后1、3、9 mo复诊,眼部伤口均愈合良好,眼球运动正常,未见肿物复发。
　　结论：表面麻醉下经球结膜手术治疗原发性结膜下眶脂肪脱垂,麻醉效果满意,手术效果好,是一种简单易行、安全有效的麻醉方法。

Effect of surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia

AIM: To evaluate the clinical efficacy of surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia.
●METHODS: A total of 22 eyes of 11 patients received surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia were included. Objective and subjective duration of the operation, degree of cooperation during surgery, postoperative recovery, recurrence and complications were observed.
●RESULTS: In the process of surgery, patients without pain and being-cooperated were recorded in 17 eyes. The patients who occasionally felt slight pain, but within endurance after adding topical anesthesia once and the operation was completed successfully were recorded in 5 eyes ( the second eye surgery ) . The operation was successfully completed in all the patients. Compared the coordination degree during surgery of Gradel with GradeⅡ, the difference was statistically significant ( t=-3. 123, P<0. 01). All eyes were healed well after operation.
● CONCLUSION: The surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia can ensure satisfactory anesthetic effect and get better quality of operation. It′s a simple, safe and effective anesthesia method for spontaneous subconjunctival orbital fat prolapse.
