External Dacryocystorhinostomy: New Dimension in Developing World

Over the last few years the study of chronic dacryocystitis is an interesting subject in clinical ophthalmology, because it being the common clinical entity encountered in routine ophthalmic practice. Surgical management of nasolacrimal duct obstruction involves the creation of a new pathway for tear flow from the lacrimal sac directly into the nose, bypassing the nasolacrimal duct this procedure, called Dacryocystorhinostomy (DCR).Comparing Endoscopic DCR ,External Dacryocystorhinostomy may be successfully performed even in small hospitals and is still gold standard procedure . The main advantage of external DCR is visualization of the anatomy, allowing precise removal of bone in the lacrimal sac fossa, and accurate suture-fixated anastomosis of the nasal mucosa and lacrimal sac. In Nasolacrimal duct obstruction population ,symptom bothers patient significantly and successful DCR surgery has a positive effect on the patient physical and psychological well being. In view of low percentage of cases who complained of marked scarring, thus scarring should not be the main ground for deciding the approach to DCR surgery, even in young cosmetically conscious patients.
