Konjenital Nazolakrimal Kanal Tıkanıklıklarında Yeniden-problama Nedenlerinin Araştırılması

Abstract

Objective: It was aimed to show the factors leading to failure of first probing, necessitating second probing application.
 Materials and Methods: In this retrospective case series, patients diagnosed with congenital nasolacrimal duct obstruction (CNLDO) between January 2010 and December 2019 and treated with a nasolacrimal duct (NLD) probe were included. The files of patients diagnosed with CNLDO and treated with NLD probing between these years at XX University were reviewed. Patients characteristics including sex, age, consultation notes, operation records, re-probing number and existence of systemic disease were recorded.
 Results: A total of 110 patients were recruited into the study finally. The mean age of patients was 17.55±5.40 (9-34) months and 46 female (41.8%), 64 male (58.2%). While the ninety three patients (84.5%) showing improvement of symptoms after the first probing considered successful, 17 patients (15.5%) having smilar symptoms regarded failed probing. Grouping patients with age less than ≤18 months or more had similar success rates with regard to probing success (p=0.250). No difference in success rate was found for gender (p=0.953) and laterality (p=0.116). Local diseases (nasal cavity problems, canalicular narrowing, anatomical variation etc.) were detected in 14 patients, who have been planned for secondary probing.
 Conclusion: Our study is in congruity with other studies claiming no effect of sex, age or laterality on probing success. If first probing fails, a thorough management plan including also exploration and handling of reasons underlying the first failure should be implemented before second probing.
