Dacryocyst Fistula Removal

The lacrimal disease is a common eye disease, in which the lacrimal duct disorder caused by inflammation is dominant. This disease is often disturbed by work, especially for outdoor work. Chronic dacryocystitis due to bacterial reproduction in the lacrimal sac, often has purulent discharge from the punctum, posing a potential threat to the safety of the eye. At present, surgical treatment is still the main cause of lacrimal disease. For the lower lacrimal duct obstruction, the dacryocystorhinostomy is used to treat the chronic dacryocystitis of the nasolacrimal duct. After continuous improvement, the curative effect is very satisfactory. In recent years, nasolacrimal duct dredge surgery has been carried out to treat chronic dacryocystitis with nasolacrimal duct obstruction. The operation is relatively simple and the curative effect is good. If the operation fails, it still does not affect the implementation of dacryocystorhinostomy or other operations. The obstacles to the upper lacrimal duct, along with the in-depth development of microsurgery, have improved and improved in terms of surgical methods and therapeutic effects. Treatment of diseases: chronic dacryocystitis Indication The lacrimal sac tube removal is suitable for chronic dacryocystitis and nasolacrimal duct obstruction. It has a history of acute dacryocystitis and forms a lacrimal sac tube. Contraindications The lacrimal sac has acute inflammation. Preoperative preparation 1. The nose and sinus should be checked first. If nasal polyps or sinusitis should be treated first. 2. Laryngeal angiography. 3. Antibiotic eye drops were given 1 week before surgery, and the lacrimal passage was washed with normal saline and antibiotic solution on the operation day. Surgical procedure 1. Expose and cut the medial malleolar ligament according to the surgical method of dacryocystorhinostomy. 2. Cut the tears apart, expose the lacrimal sac, find the lacrimal sac tube, and completely remove the fistula tissue, suture the wound. 3. Check the size of the lacrimal sac. If the lacrimal sac is small and the tissue is extremely abnormal, the lacrimal sac should be removed according to the method of removing the lacrimal sac. 4. If the lacrimal sac is larger or not too small, the dacryocystorhinostomy should be performed, and the method of making bone holes and anastomosis should be performed with the dacryocystorhinostomy. As for the choice of anastomosis method, the choice of "work" shape anastomosis or only the anterior leaflet, or the method of suturing the mucosa, should be based on the size of the lacrimal sac and the specific conditions of the mucosa. The specific method of anastomosis is detailed in the dacryocystorhinostomy.
