[A clinical study of dacryocystorhinostomy per nasal endoscope guided by endo-ophthalmic optical fiber].

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.
