Lacrimal Duct Obstruction Clinical Trial
The aim of the study is to evaluate the risk in intra-operative nasal hemorrhage when using a
"pushed" probe (Master Ka) in the treatment of naso lacrimal duct obstruction (NLDO).
In the investigator's experience, this risk seemed to minus using a pushed probe rather than
the classical pulled-type probes.
A lower risk of hemorrhage could lead to a change in the anesthetic procedure. The gold
standard in NLDO is the use of an orotracheal intubation. It could then be replaced by the
use of an orolaryngeal mask. A forthcoming study will evaluate the results of this anesthetic
change.
