Endoscopic Dacryocystorhinostomy (DCR) is a surgical intervention, performed to treat patients diagnosed with lacrimal sac or nasolacrimal duct obstruction (NLDO) which is either congenital or acquired. It is performed to restore the flow of tears into the nose from the lacrimal sac in case of nasolacrimal duct dysfunction.
Obstruction of nasolacrimal ducts lead to conditions called epiphora and dacryocystitis. Epiphora is the term commonly used to describe a watery eye caused by excessive secretion of tears due to obstruction of the lacrimal passages or the nasolacrimal duct. Dacryocystitis is an infection of the tear sac (lacrimal sac), secondary to obstruction of the nasolacrimal duct.
DCR is a minimally invasive procedure performed by ophthalmologists and otorhinolaryngologists to clear the tear ducts and correct the causes of decreased patency of the nasal passages. Generally, endoscopic DCR is considered for patients who are refractory to the conventional treatments like warm compresses, massage and probing of the nasolacrimal duct.
The procedure is performed under local anaesthesia. A decongestant is administered to clear the nasal passage first, followed by insertion of a gauze soaked in anaesthesia to numb the area.
Initially, an endoscope is inserted into the nasal cavity to the lacrimal sac through the lacrimal duct to identify and confirm the nature of the obstruction. Once the obstruction is identified, the nasal mucous membrane is incised and removed, to allow for the creation of a window on the lacrimal sac and upper nasolacrimal duct.
A portion of the lacrimal and maxilla bone is removed and a vertical incision is made in the lacrimal sac and nasolacrimal duct using a blade. Silicone tubes can be inserted to aid long-term potency of the nasal passages.
Complications may arise in the following cases:
It provides best results without any external scar and corrects the associated nasal pathology. The healing is smooth.
