The efficacy of minimally invasive repair for laceration of inferior lacrimal canaliculus

Objective To evaluate the clinical efficacy of minimally invasive repair and anastomosis of inferior lacrimal canaliculus laceration. Methods The data of 83 eyes of 83 patients with inferior lacrimal canaliculus laceration in this hospital from Dec. 2015 to Apr. 2018 were retrospectively analyzed. The study included 29 cases in the observation group and 54 cases in the control group. All cases performed surgery under the operating microscope, and the broken end of the nasal side were directly probed along the wound edge during operation. The control group adopted the ordinary anastomosis method of dual anterograde intubation with silicone stent. The observation group adopted minimally invasive anastomosis method. The lacrimal duct stent was placed into the lacrimal duct to anastomose the inferior lacrimal canaliculus laceration. All cases were followed up for 6 months. Results The operation time of the observation group was significantly shorter than that of the control group, and the difference was statistically significant (P=0.000). There was no significant difference in the recovery rate between the two groups (P=0.807). The incidence rate of puncta slitting in the observation group were significantly lower than that in the control group (P=0.046). Conclusion The minimally invasive repair for inferior lacrimal canaliculus rupture does not cause secondary injury, and the efficacy is definite.

Efficacy of application of newly designed silicone stent in the anastomosis of lacrimal canaliculus

Objective To evaluate the efficacy of application of newly designed silicone stent in the anastomosis of inferior lacrimal canaliculus. Methods The data of 45 eyes of 45 patients with inferior lacrimal canaliculus laceration from Mar. 2016 to Mar. 2018 were analgzed retrospectively. The newly designed silicone tube was implanted in the anastomosis of lacrimal canaliculus, and the broken end of the lower lacrimal canaliculus were sutured with 8-0 absorbable suture. Then the lacrimal stents were removed at 3 months after operation. The patients were followed up for 6-12 months. Results After operation, 41 patients(91.11%) were cured, 2 patients(4.44%) were improved. However, 2 patients were ineffective. The total effective rate was 95.56%. The main complications were lacrimal duct obstruction in 2 patients (4.44%) and lacrimal point tear in 1 patient (2.22%). Conclusion The newly designed silicone stent has the characteristics of simple to operate, excellent cosmetic result, safe state of catheterization and convenient to fetch tube.

Analysis of the operation timing and effect of anastomosis for 388 cases of laceration of inferior lacrimal canaliculus

Objective To investigate the surgical timing of anastomosis and efficacy of U-type silicone stent implantation for the treatment of laceration of inferior lacrimal canaliculus. Methods From Jan. 2012 to Oct. 2016, the data of 388 eyes of 388 patients with laceration of inferior lacrimal canaliculus were analyzed retrospectively. Age of all cases ranged from 2 to 79 years. There were 314 males (80.9%) and 74 females. All cases underwent double lacrimal canaliculus placement silicone stent implantation under the surgical microscope. The silicone stent was placed for 3 months and followed up for 3 months after removed. Results The difference of efficacy was not statistically significant among different operation time. At the end of follow-up, the cure rate was 78.3%, the recovery of rate was 13.6%, and the inefficiency was 8.1%. Conclusion The surgical timing of anastomosis for lacrimal canaliculus laceration should be choose before the anterior eyelid tissue edema, and it is easier to find the nasal breakage of lacrimal duct.

The analysis of 54 cases of anastomasis for traumatic lacrimal canaliculus lacerations

Objective To investigate the effective methods of anastomosis for traumatic lacrimal canaliculus lacerations. Methods The appropriate surgical methods of broken ends finding and anastomosis were performed in 54 eyes of 54 cases with traumatic lacrimal canaliculus lacerations according to their specific injuries. Results Of 54 eyes after treatment 4 cases of 48 eyes with inferior lacrimal canaliculus laceration were obstructed in early time postoperatively, 4 cases obstructed 6 months later. One case of 3 patients with superior lacrimal canaliculus laceration appeared epiphora. 3 cases with both superior and inferior laceration of lacrimal canaliculus flushed smoothly when the pipes were put out. Conclusion Appropriate surgical method according to injury condition is effective for traumatic lacrimal canaliculus laceration. Key words: Lacrimal canalicular, lacerations, traumatic; Anastomosis

Retrograde intubation for inferior lacrimal canaliculus laceration

Objective To investigate the clinical effect of lacrimal duct retrograde intubation for traumatic inferior lacrimal canaliculus laceration. Methods Forty-five eyes of forty-five cases with inferior lacrimal canaliculus laceration were retrospectively analysed. The operation was performed under operating microscope. The probing needle of lacrimal passage was inserted from the nasal broken end,Ytype nasolacrimal stent with lacrimal canaliculus was implanted retrogradely and lacrimal canaliculus was anastomosed. Results Canalicular nasal ends of all the 45 patients could be successfully found under microscope and be anastomozed. No stent slippage or formation of granulation occurred, 43 cases were cured, and lacrimal canaliculus was obstructed again in 2 cases after extubation. Conclusion Retrograde intubation for traumatic inferior lacrimal canaliculus laceration has high success rate, less injury, and less pain.

New TASER injuries: lacrimal canaliculus laceration and ethmoid bone fracture

The TASER is a non-lethal conducted electrical weapon intended to incapacitate a person. The growing use of the TASER has resulted in an increased risk of injuries, including those to the face. We report a case of lacrimal canaliculus laceration and ethmoid bone fracture caused by an extra penetration (XP) TASER X26 dart. A 35-year-old was subdued with a TASER head shot; the probe was discharged into the left medial canthus without causing any ocular lesions. A computed tomography scan revealed the probe to be embedded in the left nasolacrimal duct and showed a displaced ethmoid fracture. The barbed dart had sectioned the inferior lacrimal canaliculus without electrifying the lesion. This case expands the knowledge of injuries that may occur as a result of the use of this device and the management of peri-ocular TASER injuries.
