145 nasolacrimal obstruction patients (150 eyes) were treated with the modified dacryocystorhinostomy operation (using periostium). Group I: 45 cases with torn nasal-membrane. Group II: 145 cases with intact nasal-membrane. The general results are the same in both groups but the functional result of group II is much higher than that of group I. Thank to using periostium in operation, the treatment result is much increased. Six months after operation, the treatment result is stable. The technique is quite simple

Author has designed one of the lacrimal vinyl tube which is shaped like the root of the grass (Fig 1) and also an artificial nasolacrimal duct which can be inserted into the man's nasolacimal duct through the nose (Fig 6). It is obtained good result by inserting the root- type vinyl tube the nasolacrimal duct in the cases of the obstruction on the nasolacrimal duct, which is for making permanent lacrimal intubation. Experiment has proved there were no any troubles in the normal nasolacrimal duct by inserting the artificial nasolacrimal duct into the normal man's.

PURPOSE: In a preliminary series of 36 eyes with partial nasolacrimal duct obstruction, the types of dacryoscintigraphy result were classified and the results of silicone tube intubation were analysed. METHODS: The results of dacryoscintigraphy, performed in 36 eyes of 29 patients with partial nasolacrimal duct obstruction, were classified into the following 3 types: pre-lacrimal sac type, proximal nasolacrimal duct type and distal nasolacrimal duct type. Punctoplasty accompanied by silicone tube intubation was conducted selectively. RESULTS: In dacryoscintigraphy, symptoms improved in 6 eyes among 6 in distal nasolacrimal duct type (100%), 14 eyes among 18 in proximal nasolacrimal duct type (77.8%) and 8 eyes among 12 in pre-lacrimal sac type (66.7%). CONCLUSIONS: We conclude that dacryoscintigraphy predicts the results of silicone tube intubation. Furthermore, silicone tube intubation was effective in proximal nasolacrimal duct type and distal nasolacrimal duct type, but less effective in pre-lacrimal sac type of partial nasolacrimal duct obstruction.

The study was done on 82 eyes having nasolacrimal duct obstruction and lacrimal stenosis or stenosis-obstruction. All were treated with dacryorhinostomy (DCR) and silicone intubation. The successful prevalence is 94.4%. Among them, the prevalence of functional success is 49.9%. The successful prevalence is increasing during the follow-up time. The intra-and post-operative complications are rare and mild. The causes and the form of obstruction are prognostic factors. The recurrent obstruction may occur when the silicone tube is still inside the canalcular

PURPOSE: To evaluate clinical outcomes of silicone tube intubation according to the site of resistance to lacrimal duct probing in complete or partial nasolacrimal duct obstruction patients. METHODS: This study included 102 eyes of 72 patients who were diagnosed with complete or partial nasolacrimal duct obstruction and who underwent silicone tube intubation. According to the site of resistant to nasolacrimal duct probing, eyes were divided into proximal resistance (Group I), distal resistance (Group II) and both side resistance (Group III). The success rate was estimated based on functional (symptom relief) and anatomical (normalization of tear meniscus) success. RESULTS: The success rates in Group I, Group II, and Group III were 53.1%, 78.8%, and 27.0%, respectively, showing that Group II attained the highest success rate (Pearson chi-square test, p = 0.001). CONCLUSIONS: In cases of only distal resistance to lacrimal probing without dacryocystography, silicone tube intubation should be performed with expectation of good clinical outcomes, even if complete nasolacrimal obstruction was suspected on syringing.

In this prospective randomized controlled study, a total of 70 patients (76 eyes) diagnosed with acquired nasolacrimal duct obstruction operated by DCR with intraoperative mitomycin C 0.4mg/ml appication to the osteotomy site for 3 minutes. The results of the DRC surgeries were evaluated by objective findings such as irrigation, height of tear meniscuc, ostium size and subjective symptoms. Among the 76 eyes, 96% of patiets remained total symptoms free after 6 months of follow up. Mean ostium size 2.861 (0,785mm. There were no complications such as abnormal nasal bleeding, mucosal necrosis or infection

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.

PURPOSE: Evaluate the surgical results and clinical value of monocanalicular stenting (Monaka(R))(FCI Ophthalmics, Marshfield Hills, MA, U.S.A) and balloon catheter dacryoplasty (DCP) using PTCA balloon (Stormer(R)) for congenital nasolacrimal duct (NLD) obstruction in children. METHODS: The authors performed monocanalicular stenting (Monaka(R)) and balloon catheter (Stormer(R)) DCP as a secondary treatment of 25 children (27 lacrimal systems) over 12 months of age who had undergone ineffective probing treatment. The patients were followed up over 3 months and the postoperative outcome was assessed by fluorescein dye test. RESULTS: Nine of eleven children (nine of eleven lacrimal systems, 81.8%) and seven of nine children (seven of nine lacrimal systems, 77.7%) showed objective and subjective improvement, respectively. CONCLUSIONS: Monocanalicular stenting and balloon dacryoplasty are excellent secondary treatments for congenital nasolacrimal duct obstruction after initial probing and irrigation surgery have been failed. Balloon dacryoplasty is a new procedure in improve the life-quality and reduce the complications rather than monocanalicular stenting.
