How do you do DCR surgery?
During a DCR, your surgeon creates a new opening from the lacrimal sac to your nasal cavity. The surgeon makes a small incision in the skin, in the area under your eye and next to your nose. Through this incision, your surgeon creates a small opening in the bone beneath.
What is endonasal DCR?
Technique (Endonasal/Endoscopic DCR): The primary benefit of the endonasal, or internal, approach is the lack of skin scarring. The nasal mucosa and middle turbinate are first decongested for vasoconstriction and hemostasis.
What is Laser DCR?
Transcanalicular endoscope combined laser assisted dacryocystorhinostomy (Transcanalicular ECLAD) is a new minimally invasive dacryocystorhinostomy procedure which is performed by diode laser through lacrimal canaliculi with the help of a cannula and fibre optic cable.
Which bone is broken in DCR surgery?
A DCR procedure involves removal of bone adjacent to the nasolacrimal sac and incorporating the lacrimal sac with the lateral nasal mucosa in order to bypass the nasolacrimal duct obstruction. This allows tears to drain directly into the nasal cavity from the canaliculi via a new low-resistance pathway.
What do you need to know about DCR surgery?
What is a dacryocystorhinostomy (DCR)? A DCR is a type of surgery that is used to treat blocked tear ducts in adults. It creates a new passageway between the tear duct sac and the nose, bypassing the blockage and allowing tears to drain normally again.
Where does the DCR surgery take place in the eye?
A DCR operation effectively makes a new passage for the tears to pass from the eye to the nose. This new passage or bypass joins the upper part of the main tear duct (the tear sac) to the inside of the nose after removing a small area of bone that lies between the tear sac and the inside of the nose.
Where does the tubing go after DCR surgery?
This tubing is just visible at the inner corner of the eye where it passes between the upper and lower tear duct openings. Its purpose is to protect the lining of the new tear passage while it is healing. It is removed painlessly through the nostril after several weeks.
How is a Dacryocystorhinostomy ( DCR ) performed?
Dacryocystorhinostomy (DCR) describes the creation of a functional pathway from the canaliculi into the nose by means of creating an osteotomy and opening the nasolacrimal sac into the nose. It can be performed via an external or endonasal approach.
When do you need a DCR tear duct surgery?
What is a DCR? A dacryocystorhinostomy (DCR) is a type of surgery done to create a new tear drain between your eyes and nose. You may need this surgery if your own tear duct has become blocked. Your eyelids have two small openings that drain some of the tears covering your eye. Blinking pushes tears into these openings.
What kind of surgery is Dacryocystorhinostomy ( DCR )?
Abstract Dacryocystorhinostomy or DCR is one of the most common oculoplastics surgery performed. It is a bypass procedure that creates an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. There are two clear goals of DCR procedure. One is to make a large bony osteum into the nose and that remains so.
Where are the incisions made for a DCR?
During a DCR, your surgeon creates a new opening from the lacrimal sac to your nasal cavity. The surgeon makes a small incision in the skin, in the area under your eye and next to your nose. Through this incision, your surgeon creates a small opening in the bone beneath.
What are the side effects of DCR surgery?
Damage to the medial rectus and superior oblique may cause diplopia. Blindness may occur from damage to the intraorbital vessels or optic nerve. Sump syndrome may occur if the rhinostoma is small and high up in the lacrimal sac. This causes tears and mucus to accumulate in the sac and discharge into the eye.
