高密度多孔聚乙烯人工泪管植入治疗外伤性泪道阻塞的疗效分析

目的观察内窥镜指导下高密度多孔聚乙烯（high-density Porous polyethylene,HDPP）人工泪管植入治疗外伤性泪道阻塞的疗效。方法外伤性泪小管离断患者12例（12只眼）,行高密度多孔聚乙烯人工泪管植入术,术后随访6-24个月,平均随访15个月。结果术后患者溢泪症状消失或明显改善,所有人工泪管均冲洗通畅,术后并发症包括人工泪管结膜侧管口中度肉芽增殖1例（8.3%）,管口周围结膜组织肥厚1例（8.3%）,局部不适感2例（16.6%）。结论 HDPP人工泪管植入手术能明显改善外伤性泪道阻塞患者的溢泪症状,术后无严重并发症,该手术安全有效。

The study of therpaeutic effects of endoscopital implantation with the high-density porous polyethylene (HD-PP) coated tear drain treated traumatic lacrimal canaliculus disruption

Objective To objective the therpaeutic effects of endoscopital implantation with the high-density porous polyethylene（HDPP） coated tear drain treated traumatic lacrimal canaliculus disruption. Methods Twelve eyes of 12 cases with？ traumatic inferior and（or） superior lacrimal canaliculus disruption who was took endoscopital implantation using the high-density porous polyethylene（HDPP） Coated tear drain. All patients were followed up for a mean duration of 15 months following surgery（range 6-24months）. Results Postoperative epiphora disappeared or significantly improved,all the HDPP tubes are rinsed unobstructed,postoperative complications included hypertrophic conjunctival tissue side of the orifice（1 eye）,hypertrophic conjunctival tissue surrounding the orifice（1 eye）,local discomfort three cases（2eyes）.Conclusion The high-density porous polyethylene（HDPP） is an effective device for CDCR.
