Tear is produced by the tear glands located under the eyelids. It is essential for the eye to keep moist and provide its normal function. Tear glands and tear ducts carry the secreted tear to the nasal cavity. The obstruction of these ducts due to various reasons is called “Epiphorea”.
Tears might secrete out of the eye or if repeating tear gland infection is present, medical treatment is applied. If the blockage is non-responsive to the applied treatment or the transfer of tears to the nasal area is failing, the tear gland is surgically connected to the nose. DSR surgeries are operations that are applied on patients where they have an obstructed lacrimal sack or lacrimal duct.
Classically applied surgical technique requires an external incision and then the tear gland is located and connected to the nose.
It is even easier to get over the lacrimal bone in the endoscopic surgical technique, reducing complications and operation time significantly. After the blockage has been removed, a silicon tube is inserted into the lacrimal duct, and this tube is removed after three to six months of surgery without the need of anesthesia.
Endoscopic Dacryocystorhinostomy surgery’s advantages over classic surgery;
- Tear Duct functions are not affected as much
- There is no incision or scar left
- Operation time is shorter
- Healing and Recovery time is shorter
Diagnosis and treatment of tear duct diseases should be made by Ophthalmologists and also the surgical operation decision should be made by them.
