Complex stenosis

DON'T UNDERESTIMATE THE IMPORTANCE

OF A NASOLACRIMAL STENOSIS

 

 

a)   SYMPTOMS : 

                    - Nasolacrimal stenosis is unusually tight.

                    - Probing is done to determine if this is a case of false passage or a complex stenosis.

                   - Absence of metalic contact (Unless the guide probe perforate the surrounding anatomic structures).

 

 

      b) RISKS : Failure of the procedure.

- The guide may pass through the nasolacrimal stenosis with difficulty, but the silicone usually bunches up arround the introducer without passing through the stenosis.

 

                

                 - This is an équivalent of a stent that is too short and will result in an unsuccessful treatment.

 

c) WHAT TO DO ? :

- Remove the Masterka and examine its inferior extremity. 

- Redo the intubation AND check the metal-to-metal contact.

 

In case of residual doubt, switch to a classical intubation procedure.
