Description
Summary:The purpose of this study is to assess the long-term outcomes of modified transcanalicular diode laser dacryocystorhinostomy in a large cohort of patients affected by primary acquired nasolacrimal duct obstruction. This study, conducted from January 17 to June 2022, encompassed 141 patients (159 procedures) who underwent modified transcanalicular diode laser dacryocystorhinostomy (MT-DCR). The procedure employed an 810-nm diode laser. Patients were monitored for at least a year after the intervention. Anatomical success was determined by ostium patency upon irrigation, while functional success referred to epiphora resolution. Parameters studied included patient demographics, procedure duration, complications, and both anatomical and functional success. Statistical analysis was performed using the Statistical Package for the Social Sciences software, with results considered significant at a 95% confidence interval (p≤0.05). A total of 159 lacrimal drainage systems (141 patients: 112 women and 29 men) were included in this study. Among them, 18 underwent bilateral procedures. The average patient age was 58 years (range: 34-91 years), and the average surgical duration was 24 minutes (range: 18-35 minutes). One year after the surgery, MT-DCR exhibited anatomical and functional success rates of 84.9% (135/159) and 83% (132/159), respectively. MT-DCR achieved an anatomical success rate of 84.9%, reflecting an excellent outcome. However, further extensive studies with larger sample sizes and longer follow-up periods are necessary to substantiate these findings.
