Eight cases of surgically repaired lower canaliculi were studied to ascertain whether the lower canaliculus is necessary for normal lacrimal drainage and whether it is advisable to probe the superior canaliculus during inferior canalicular repair. Six of 8 patients sutdied had no epiphora despite unsuccessful surgery and a normal Schirmer"1 test. Surgery was successful on 2 pateints. These results indicate that only cosmetic repair is necessary for lacerated lower canaliculi. It is suggested that the upper canalliculus alone provides sufficient lacrimal drainage to prevent epiphora.
对8例接受手术修复下泪小管的病例进行了研究，以确定下泪小管对正常泪液引流是否必要，以及在修复下泪小管时探查上泪小管是否可取。在研究的8例患者中，有6例尽管手术失败且泪液分泌试验（Schirmer试验）结果正常，但并无溢泪症状。2例患者手术成功。这些结果表明，对于撕裂的下泪小管，仅进行美容修复即可。建议仅上泪小管就能提供足够的泪液引流以防止溢泪。
