Abstract
Introduction: Dacryocystorhinostomy (DCR) is the mainstay management of choice for Chronic Dacryocystitis. External DCR is the standard treatment procedure of choice. In the recent past it has been observed that endoscopic DCR is growing as an equally successful substitute for the management of chronic acquired naso-lacrimal duct obstruction.
Aims: This study intends to compare the final result of surgical management of acquired naso-lacrimal duct obstruction between external DCR and endoscopic endonasal DCR.
Method: This is an observational study. This study was carried out in the Ophthalmology department and Otorhinolaryngology department, Burdwan Medical College and Hospital from October 2013 to September 2014. Total 60 patients were included for DCR operation. Out of which 30 patients underwent endoscopic endonasal DCR in the department of otorhinolaryngology and 30 patients underwent external DCR in the department of ophthalmology. Data were collected and analyzed on the basis of ocular examination, lacrimal pathway, postoperative complications and finally surgical outcome. Resolution of patient’s symptoms and patency of lacrimal drainage system were used to define as successful surgical out come. Postoperatively persistent of symptoms and non patency of the lacrimal pathway were used to define as failure. Statistical analysis was done with the help of Statistical software Epi Info Version 7.
