Purpose: to determine the success rate of bilateral dacryocystorhinostomies (DCR) using simultaneous and asynchronous approach.
Methods: this retrospective study included patients who underwent bilateral external DCR between January 2010 and August 2015 at King Khaled Eye Specialist hospital. Postoperative success defined as absolute if no tearing bilaterally or partial if tearing in one side only was assessed by subjective (symptoms of tearing) and objective (fluorescein dye disappearance test - FDDT) methods. Statistical analysis was performed applying the Fisher exact test.
Results: of 57 patients undergoing DCR 32 (56%) had simultaneous surgeries on both sides while in 25 patients, the surgery was asynchronous. The median duration of follow up was 7 months. The absolute success and partial rate based on subjective method was 43/55 [(78.2% (67.3 – 89.1)]. Partial success was noted in 5/55 (9.1%).Seven (12.7%) patients persisted with tearing on both sides. The objective method (n = 40) showed similar results in patients undergoing simultaneous (71.9%) and asynchronous (80%) DCR (p=0.4).
Conclusions: bilateral DCR surgery is useful in patients who have bilateral symptoms of lacrimal obstruction due to blockage of tear ducts and gives promising outcomes. By performing the DCR simultaneously, the success rate is not compromised, and one can rehabilitate patient sooner.
