Objective:
To get a method of dacryocyst allocation for dacryocystorhinostomy per nasal endoscope.
Method:
The dacryocyst of 7 chronic dacryocystitis cases(8 eyes) were located through nasal cavity guided by endo-ophthalmic optical fiber.
Result:
All the 7 patients got successful operations, the bleeding was 10-20 ml during the operation , postoperative recovery was good, no infection occurred. Five patients received operations twice, all of them were detained anaesthetic tubes for 3 to 6 months, dacryocyst rinsing were conducted once per month after extubation. No obstructions and complications occurred after one year follow up.
Conclusion:
Endo ophthalmic optical fiber can be used to locate dacryocyst in dacryocystorhinostomy per nasal endoscope.
