Tobramycin and dexamethasone ointment was applied to the fistula to end the operation.1% epinephrine hydrochloride 2 ml soaked cotton pads, and nasal mucosal surface anesthesia 2 Times, 5 min/time. Our hospital uses nasal endoscopy to perform dacryocystostomy again for the above patients, using polytetrafluoroethylene membrane as a support material during the operation, indwelling for 1 to 3 months, and achieving satisfactory results.5% proparacaine hydrochloride solution for eye drops, 1% dicaine 10 ml plus 0. A sickle knife cuts the mucosa and scar tissue around the lacrimal duct probe to make a dacryocystostomy about 8 mm\u0026times; 8 mm in size to fully stop bleeding.
Use a lacrimal probe to introduce a No.【Abstract】 Objective: To investigate the clinical efficacy of polytetrafluoroethylene membrane in recurrent dacryocystitis surgery. Methods: Twenty-three patients (23 eyes) with recurrent dacryocystitis used polytetrafluoroethylene membrane as Gas Top Protectors Factory the supporting material for the pore formation during the nasal endoscopic ostomy. 0 silk thread into the nasal cavity from the lower lacrimal point to form a thread loop. However, with the development of medical technology and technology, the dacryocystorhinostomy under nasal endoscopy provides a new surgical method for patients with chronic dacryocystitis, which is even more evident in the treatment of patients after the failure of traditional dacryocystorhinostomy Out of its advantages. 2% lidocaine hydrochloride, 1 ml of infraorbital nerve block anesthesia, 1 ml of nasal cavity mucosal dacryosac projection area submucosal anesthesia.3%.9%, 4 cases improved, the improvement rate was 17.
Nasal endoscopic dacryocystorhinostomy; polytetrafluoroethylene membrane; recurrent dacryocystitis Nasal cavity endoscopic dacryocystorhinostomy for dacryocystitis has been gradually promoted in clinical practice, but the postoperative dacryocystorhinostomy often becomes atresia due to excessive tissue proliferation [1-3], and anastomotic scar atresia is tears The main reason for the recurrence of bursitis [4-7]. Some patients can penetrate the nasal cavity from the original fistula with a little force to remove blocked blood clots, secretions and necrotic tissues. The report is as follows.4%, and the effective rate was 91. 1. The longest time from operation is 2 years, the shortest is 30 days, and the average is 15 months. A total of 23 cases (23 eyes) were collected, including 9 males (9 eyes) and 14 females (14 eyes), aged 40 to 59 years old, with an average of 52.
Materials and methods 1. Conclusion: Polytetrafluoroethylene membrane as a support material for pore formation in recurrent dacryocystitis can effectively improve the success rate of the operation and provide good patient comfort. Surgical exploration confirmed that there were varying degrees of scar contraction and granulation growth at the anastomotic site of the lacrimal sac, resulting in anastomotic occlusion. The lacrimal sac was pulled into the fistula about 4 mm, and one end of the silk thread was cut and removed at the lower punctum.1 General data selection of patients with recurrence after nasal endoscopic dacryocystorhinostomy from January 2010 to January 2012 due to chronic dacryocystitis, manifested as recurrence of lacrimal and pus symptoms after the operation, and the lacrimal duct is not flushed unobstructed.
The lacrimal duct probe lifts the nasal mucosa through the inferior lacrimal canaliculus through the original fistula of the lacrimal sac.. The postoperative follow-up was 3-6 months.1 years old.2 Surgical method The patient is placed in a supine position, routinely disinfected drapes, 0. Recurrent dacryocystitis after nasal endoscopic dacryocystostomy is a clinical problem that needs to be solved urgently. Results: 17 cases were cured, the cure rate was 73. If the original bone hole is found to be small during the operation, use an electric drill to enlarge the bone hole to 8 mm\u0026times; 8 mm. The high temperature and high pressure sterilized polytetrafluoroethylene film with a length of about 40 mm and a diameter of about 4 mm is folded on the thread loop.
