Abstract
IntroductionAny disturbance to the normal ouVlow of tears through the nasolacrimal passage causes overflow known as epiphora. The clinical symptoms of epiphora range from mild dribble to the continuous ouVlow of tears. Watering of eyes caused by the nasolacrimal drainage obstruction is managed by surgery. One of the many surgeries to treat this is external dacryocystorhinostomy.ObjectiveThe objective of this study was to evaluate the success rate of external dacryocystorhinostomy as well as factors affecting it.MethodologyThis is a retrospective cross-sectional study, conducted in the Department of Ophthalmology, B. P. Koirala Institute of Health Sciences (BPKIHS), Dharan with the approval of Institutional Review Committee, BPKIHS. The medical records of patients who underwent external Dacryocystorhinostomy surgery from April 2011 to April 2016 at BPKIHS were retrospectively reviewed. Statistical analysis was performed using SPSS for windows, version 11.5 (SPSS Inc., Chicago, IL). Binary logistic regression models were used to investigate the association of the surgical outcome with various predicting variables.ResultsThe success rate of the external dacryocystorhinostomy was 78.09%. Factors studied were: age, with a range of 2-81 years; duration of symptoms with a range of 1-84 months; and gender of the patients. The intra-operative factors studied were use of silastic tube, types of flap, and osteotomy size. Among these factors, the duration of symptoms and osteotomy size had significant association with the outcome of the surgery p<0.05.ConclusionOur study yielded high success rate in patients with shorter duration of watering of eyes and larger osteotomy size during surgery. Hence, a larger osteotomy size and early intervention is recommended for better surgical outcome. Birat Journal of Health Sciences Vol.2/No.1/Issue 2/ Jan - April 2017, Page: 196-200
Highlights
Normal flow of tears from the eye to the nose is through the nasolacrimal passage
The pa ents included in the study were with the diagnosis of nasolacrimal duct obstruc on based on the history of watering of the eyes and the presence of regurgita on of fluid or mucopurulent discharge on pressure over the lacrimal sac (ROPLAS) and reflux of fluid on syringing of the lacrimal passage
The binary logis c regression was conducted to predict the successful outcome of an external DCR surgery using age, dura on of symptoms, gender, use of Silas c tube, type of flap surgery and osteotomy size
Summary
Normal flow of tears from the eye to the nose is through the nasolacrimal passage. Any disturbance to the normal ou low causes overflow of tears known as epiphora. Nasolacrimal duct obstruc on is successfully managed by a procedure known as external Dacryocystorhinosotmy (DCR). External DCR Technique introduced by To was later modified with suturing of the anterior and posterior lacrimal and nasal flaps by Dutemps and Bourget in 1921.1. External dacryocystorhinosotmy (DCR) ll today remains the gold standard technique for the management of nasolacrimal duct obstruc on. Since 1980, another technique of DCR surgery, Endoscopic endolaser DCR has been popularized as an alterna ve op on for the conven onal external DCR surgery.[2,3,4,5] Endolaser assisted DCR surgery was introduced by Massaro et al in 1990.6 Other techniques of DCR surgeries are transcanalicular laser dacryocystorhinostomy,[7] conjunc v odacryocy storhinostomy.[8]
