Abstract:AIM: To investigate the clinical curative effect of double loop insertion of silicone rubber tube combined with "Z" flap repair in the treatment of laceration of eyelid with canaliculus laceration.
METHODS: The paper reviewed 45 cases of laceration of eyelid with laceration canaliculus, caused by trauma, which were treated in my hospital from January 2014 to January 2016. In the process of anastomosis of lacrimal duct and suture of eyelid laceration, either the method of single spinal anesthesia tube placement on skin contraposition suture or the method of dual annular silicone tube placement combined with the word "Z" flap repair was used. We compared the two methods and studied the possible complications like eyelid varus and valgus, lacrimal point valgus, eyelid scar, anastomotic dehiscence again.
RESULTS: Out of the 22 cases in which the patients chose the single spinal anesthesia tube implantation on skin suture, 21 cases succeeded and patients received lacrimal duct patency results after extubation; and 1 case anastomosis failed. Complications: 20 cases had different degree of complications and the impact on their appearances were significant. Out of the 23 cases in which the patients chose double passage annular silicone tube joint prosthesis implantation Z flap, 23 received extubation results lacrimal patency or almost patency, the anastomosis of patients was successful. Complications: in two cases, patients had mild eyelid entropion and pomatum varus. Both eyelid deformity and severe wound tear did not occur in all cases again. Scar was not obvious. The success rate of anastomosis between the two groups was not significantly different(P=0.4889). To compare the rate of complications, there were significant differences(χ2=30.42, P<0.05).
CONCLUSION: The application of dual ring implantation silicon tube combined with the word "Z" flap repair in the treatment of lacrimal canaliculi laceration of eyelid laceration ensured the success rate of lacrimal canalicular anastomosis, greatly improved the eye appearances, and reduced the incidence of postoperative complications.
