Recanalization of Congenital Nasolacrimal Duct Obstruction by Endodiathermy Probe and Intubation Versus Intubation Only

Recanalization of Congenital Nasolacrimal Duct Obstruction by Endodiathermy Probe and Intubation Versus Intubation Only

The purpose of the current work is to assess the efficiency and success rate of endodiathermy probe followed by intubation in children more than 2 years compared to the success rate of intubation (as a standard method) which varies from 75% to 85% in several studies

The study will be conducted on children above 2 year and will be divided randomly into two groups:

Group (I): 80 eyes of children suffer from congenital nasolacrimal duct obstruction will have probing with metal probe and then intubation with bicanlicular silicon tube.

Group (II): 80 eyes of children suffer from congenital nasolacrimal duct obstruction will have probing with endodiathermy probe and then intubation with bicanlicular silicon tube

Inclusion Criteria:

1. Children in the age group above 2 years old
2. No history of previous probing.
3. No history of previous intubation.
4. Children with no any other association or congenital anomalies cause watery eye.
5. children suffer from congenital nasolacrimal duct obstruction.

Exclusion Criteria:

1. children less than 2 years old.
2. previous probing.
3. previous intubation.
4. children with any other congenital anomalies as congenital ectropion , congenital entropion
5. children suffer from any upper lacrimal anomalies as obstruction or stenosis.
