摘　　要：Objective： To investigate the necessity of modification to the traditional pigtail probe and evaluate its efficiency and therapeutic effect in searching the nasal cut ends and anastomosing the lacerated lacrimal canaliculus. Methods： Eighty-seven patients （including 87 eyes） suffering from canalicular laceration were randomized into two groups： 41 patients treated with traditional pigtail probes （Group A） and 46 with modified pigtail probes （Group B）. During the reconstruction of the lacerated canaliculi, the traditional pigtail probe and the modified pigtail probe were used respectively to seek for the nasal cut ends of lacerated lacrimal canaliculi. Peripherally inserted central catheter （PICCTM） silicone tube with diameter of 0.95 mm was intubated as a stent for 4-6 months. The surgical outcomes were retrospectively analyzed after stent removal. Results： In Group B, the primary success rate of searching the nasal cut ends of lacerated lacrimal canaliculi was 93.48% （43/46） and the final success rate was 97.83% （45/46）. No false passage formed in Group B. Statistical sig- nificance was found between Group A and Group B as the primary success rates of searching the nasal cut ends （ x^2 = 10.522, P〈0.01） and the false passage forming rates were concerned （ x^2=4.704, P〈0.05）, whereas no significance was found between the two groups as the final success rates were concerned （ x^2=0.007, P〉0.05）. The mean time of searching the nasal cut ends of lacerated lacrimal canaliculi in Group B was （5.02±2.73） minutes and the mean time of operation was （33.90±4.84） minutes, and both were significantly shorter than those of Group A （t1=9.779, t2=10.700, P〈0.01）. The cure rate of Group B was 95.65%, though higher than that of Group A, no statistical significance was found （Z=-1.007, P〉0.05）. Totally, 2 patients （2.30%） were found to be absent of common canaliculus and underwent bicanalicular nasal intubation in the two groups. Conclusions： Pigtail pr
