The epiphora is usually distress to the patient not only in physiological aspect but also in psychological aspect.
The obstruction of nasolacrimal conduit system, which may-produce epiphora can be caused by congenital anomalies, chronic dacryocystitis, after ablation of lower lid carcinoma, trauma and facial paralysis.
Especially, severe naso-orbital fracture can be obstructed the bony nasolacrimal canal or total lacrimal conduit system.
The epiphora with damage to the nasolacrimal duct will require a dacyocystorhinostomy or conjuntivodacryocystorhinostomy.
The conjuntivorhinostomy should be considered in the cases of totally occluded nasolacrimal conduit system, failed dacryocystorhinostomy, or failed conjunctivodacryocystorhinostomy.
By using the nasal funnel flap method, the authors performed conjuntivorhinostomy in patients with the obstruction of nasolacrimal conduit system and obtained the following conclusions:
1. The new created lacrimal conduit have maintained good patency.
2. None of the patients had significant epiphora and purulent discharge.
3. There are no nasal deformities and operation scars are insignificant.
We experienced 3 cases of the nasal funnel flap method and recognized that this technique can provide functional and cosmetical advantages than other conventional conjuntivorhinostc my.
