Tear duct intubation: a trip to the center of the nasal cavity

Surgeon: Dr Pierre Escalas

Institut Ophtalmologique Sourdille Atlantique Nantes / Saint Herblain

Intubation of the lacrimal tract is indicated for congenital obstruction of the nasal lacrimal duct in children. This duct carries tears from the inner tongue of the eye to the nasal cavity and opens under the lower turbinate. This video describes the anatomy of the nasal cavity, which must be reconstructed mentally in order to be able to find the probe without traumatising the surrounding mucous membrane.


The videos have been created and produced with great care to be as relevant as possible. Many topics are controversial and the options presented are rational personal choices, the result of an experiment involving several thousand interventions. Other ways of doing things are possible, they may have been proposed to you, so do not hesitate to ask for the reasons for the choices that were made.

This site is only a guide and does not replace the explanations given in a consultation, which are essential for understanding the analysis of the characteristics of your face, which is unique.

In the same way, the examples presented allow you to understand the principles of eye surgery, but they are not necessarily transposable to your particular situation. It is therefore not possible to guarantee the results that you have seen on the different presentations.

By consulting this site, you accept these limits. If you do not, I ask you not to use it.
