Silicone tube implantation retrograde lacrimal obstruction 36 Cases
If efficacy of the standard cure: the symptoms disappeared, lacrimal patency. Improvement: mild tears, lacrimal pass the poor. Invalid: no improvement of epiphora, lacrimal barrier. All 3 efficacy to reduce postoperative epiphora, flushing smooth, no infection. 56 eyes of 36 cases, aluminum cases cured 3o eyes, 87%; 4 cases improved, 5 eyes, 9%; 2 cases 3, 5%. The total effective rate was 95%. After treatment, follow up of 1 to 5 months, 5 cases of recurrence, 3 cases of lacrimal, anti-inflammatory drug application for 3 weeks to cure. Another bone of both sides of the narrow, to dacryocystorhinostomy. 4 to discuss the pathological changes of lacrimal duct obstruction is mainly swelling of lacrimal inflammation,[link widoczny dla zalogowanych], tissue hypertrophy, adhesions, stenosis, occlusion. Treatment to tears and back to the main function. Treatment to treatment dacryocystorhinostomy better L2j, but the larger surgical injury, the elderly and infirm can not be tolerated. Surgical treatment of complicated and normal physiological changes in the tear channel. Retrograde many surgical methods [3,4,5], but there is no justice management flexibility,[link widoczny dla zalogowanych], the lack of auto-expansion feature. The quality of intubation, choice of materials is to increase the recanalization and prevent complications. The soft silicone tube, the surrounding tissue irritation, tissue compatibility, a super-elasticity and toughness, by the strong pull into a thin strip without fracture,[link widoczny dla zalogowanych], lacrimal duct stenosis after implantation, there is little hollow, super-elastic recovery of the original tube shape, wall holes open, to be carried out liquid rinse, tear duct wall is rich in elastic fibers of connective tissue that surrounds the inner layer is covered by stratified squamous epithelium, when the tears channel wall to clear the obstruction by laser vaporization or the formation of false passage of a new wound, the connective tissue around the supports local growth, the formation of channels, on the growth of cortical cells crawl along the wall covering in the channel, the formation of new epithelial lacrimal duct recanalization. Combined retrograde laser lacrimal silicone tube implants, avoid the result of nasolacrimal duct stenosis and after simple laser caused no recurrence of support issues, the operation carried out under the direct directional positioning, which is simple, safe, no pain, no complications, recurrence less good effect. The introduction of the surgical Class Y-nasal silicone tube, the quantitative orientation of surgery under direct vision in the surgery to ensure the safe, simple, good effect. ... The super flexible silicone tube and toughness, to support expansion of lacrimal duct to prevent adhesion formation, so that duplication of lacrimal epithelial repair, to keep them open. While in the tube, but also at the same time lacrimal, drug into the tear duct to reduce inflammation, inhibit scar formation and restore normal function of the mucosa, improve the efficacy, shorten the course. The method is compared with dacryocystorhinostomy, surgical method is safe, simple,[link widoczny dla zalogowanych], pain, effect, no serious complications, repeatable operation. Lacrimal duct obstruction is a common multiple, by the anatomical defects of factors, inflammation, trauma and other reasons. Distribution of each age group. Inflammation is the main reason. The anatomy and physiology of lacrimal are closely linked. Because lacrimal tortuous, thin diameter, no voluntary movement muscles, bureaucratic organization and the mucosal lining of the lower conjunctival sac is directly connected with the nasal mucosa, conjunctiva and nasal cavity are the body's defense system, cutting-edge,[link widoczny dla zalogowanych], susceptible to external pathogenic factors invasive, easy to spread tear duct. Lacrimal duct obstruction led directly to cry, visual disturbances, long plagued the lives of patients and work associated with dacryocystitis adjacent tissue infections may cause serious consequences. I am the main town of population distribution in the factory, the workers come from rural mountain areas, to collective accommodation based, meaning the majority of poor self-care, the incidence of lacrimal duct obstruction is also higher. In order to improve community health, improve people's health awareness and improve the quality of life, treatment of lacrimal duct obstruction disease, increasing the cure rate has become an important task.
