What I treat
Nasal Endoscope
The nasal endoscope is used as an auxiliary means during the procedure of probing the tear duct or placing a tear duct stent in some cases of congenital nasolacrimal duct obstruction in children. The importance of this technique lies in the fact that it gives the doctor a direct view of the nasal cavity and the end of the tear duct, which helps to evaluate the duct and deal with it with a greater degree of accuracy, and detect some problems that may not be able to be evaluated clearly using traditional methods.
Who it's for
The nasal endoscope is used to diagnose and treat some complex blockages when the nasolacrimal duct obstruction is due to a change or anatomical deformity in the lower part of the duct. In some cases, the cause of the blockage can be addressed and treated from inside the nose during the procedure. It is also performed to evaluate the nasal cavity, where the endoscope allows for examination of the nasal cavity before and during the procedure, and identification of any problems or blockages inside the nose, especially enlargement of the inferior nasal turbinate.
What to expect
During the procedure, the tear duct is usually cleared or a tear duct stent is inserted, with or without displacement of the lower nasal conchae, depending on the nature of the case. The use of a nasal endoscope helps to perform these steps with greater precision, especially when displacement of the lower nasal conchae is required, as it provides a direct and clear view of the area, helping to avoid unnecessary injury to surrounding tissues. The endoscope also allows for the identification of the true path of the tear duct and direct visualization of its end inside the nose, giving the physician confirmation during the procedure that the stent or catheter is following the correct path and is in the proper position, rather than relying solely on indirect estimation. This enables the intervention to be performed with greater precision and safety, reducing complications and improving the chances of successful treatment.
