The study was done on 9 children aged from 4-16 with 10 eyes having congenital or traumatic naso-lacrymal duct obstruction. These eyes with associated canalicular stenosis or obstruction were treated by dacryorhinostomy (DCR) and silicone intubation in six months. The successful prevalence of DCR is as high as that of DCR on adult: 90%. Among them, 70% were functional success. One eye having recurrent obstruction is traumatic case. The failure occurred when silicone tube is still inside the canacular. DCR in children is not difficult than that in adult. The complication is rare and easy solved.

The diagnosis and treatment of the lacrimal passage obstruction with lacrimal endoscope was investigated and its subsidiary surgical procedures were evaluated. Ninety-three patients (109 eyes) with lacrimal passage obstruction, including presaccal canalicular obstruction (PSCO) and nasolacrimal duct obstruction (NLDO), were examined under a lacrimal endoscope, and the obstructions were treated with laser or micro-drill. All patients were followed up after the operation for 3-6 months. The difference between the laser and the micro-drill treatment was observed. During the period of follow-up, the curative rate was 82.57%. The healing rate in PSCO group and NLDO was 80.36% and 84.91% respectively (P>0.05). After treatment with the laser, the healing rate was 93.33% in the PSCO group and 66.67% in the NLDO group respectively (P<0.05). After treatment with the micro-drill, the healing rate in PSCO and NLDO groups was 65.39% and 94.28% respectively (P<0.01). The lacrimal passage obstruction can be observed and treated directly through the lacrimal endoscope. Choosing different surgical procedures in operation according to the locations of the obstruction is helpful to improve the effectiveness.

PURPOSE: This study investigated the surgical outcomes of canalicular trephination combined with endoscopic dacryocystorhinostomy (DCR) in patients with a distal or common canalicular obstruction. It also identified the factors affecting surgical success rates associated with this technique. METHODS: We retrospectively reviewed the medical records of 57 patients (59 eyes) in whom a canalicular obstruction was encountered during endoscopic DCR. All patients were treated with endoscopic DCR, followed by canalicular trephination and silicone tube placement. The surgical outcome was categorized as a functional success according to the patient's subjective assessment of symptoms, including epiphora, and as an anatomical success according to a postoperative nasolacrimal duct irrigation test. Surgical success rates were compared based on age, sex, location of the obstruction, number of silicone tubes, and experience of the surgeon. RESULTS: Functional success was achieved in 55 of 59 eyes (93%) at one month, 50 eyes (84%) at three months, and 46 eyes (78%) at six months. Anatomical success was achieved in 58 of 59 eyes (98%) at one month, 52 eyes (88%) at three months, and 50 eyes (84%) at six months. There was a statistically significant difference in surgical outcome according to the experience of the surgeon. The anatomical success rate at the six-month follow-up exam was 95.4% in the >5 years of experience group, and 53.3% in the <5 years of experience group (p = 0.008, Pearson chi-square test). CONCLUSIONS: The success rate of canalicular trephination combined with endoscopic DCR in patients with a distal or common canalicular obstruction decreased gradually during the six-month follow-up period. In particular, patients undergoing procedures with experienced surgeons tended to show excellent surgical outcomes at the six-month follow-up exam.
