严重的泪小管外伤可使泪小管部分缺损,致使断端无法直接吻合。1984～1991年间我们采用塑料管做支架行泪小管再生术,治疗12例,治愈好转率91.6%。手术方法简单,泪小管缺损8mm以内均可采用此方法。泪小管上应组织为复层鳞状上皮细胞,再生能力强。泪小管缺损后,放置支架,使上皮细胞沿管壁爬行,形成新通道,可恢复泪道导流功能。 Serious traumatic canalicular trauma can tear part of the canalicular defect, resulting in the stump can not be directly matched. From 1984 to 1991, we used plastic tube as a scaffold to repair lacrimal canaliculus. Twelve cases were cured, and the healing improvement rate was 91.6%. Surgical methods are simple, tear canal defect within 8mm can be used this method. The lacrimal duct should be organized into stratified squamous epithelial cells, regenerative ability. After lacrimal canalicular defect, the stent is placed so that the epithelial cells crawl along the tube wall to form a new channel, which can restore the function of the lacrimal duct.
