Long-TemM Results in Transcanalicular Laser and External Dacryocystorhinostomy

Abstract

This study was an examination of the long-term results of transcanalicular laser (TCL) and external (EX) dacryocystorhinostomy (DCR). Methods: Patients who had undergone TCL-DCR or EX-DCR between 2009 and 2013 were invited for long-term follow-up in 2019. All of the patients who responded had an ophthalmic examination and were assessed using lacrimal irrigation. An intranasal evaluation was performed when the irrigation test had non-patent results. TCL procedures were performed with a diode laser (980 nm). Ostium cleansing with a suction unit and a nasal endoscope was performed in the first week. In EX-DCR procedures, an anterior flap was created and tented to the orbicularis oculi muscle. A silicon tube was implanted in both methods and removed at 4-6 months. Results: A total of 74 EX-DCR patients were assessed. The lacrimal irrigation test was negative in 5 cases. The functional success rate was 93.2% with a follow-up of 8 years. A total of 63 patients who had undergone TCL-DCR were evaluated and the irrigation test was negative in 9 patients. The functional success rate was 85.7% with a follow-up of 7 years. The difference in the success rate was statistically insignificant with a p value of 0.09. Conclusion:The long-term success rates of both EX-DCR and TCL-DCR were high.

Transcanalicular Multidiode Laser Versus External Dacryocystorhinostomy in the Treatment of Acquired Nasolacrimal Duct Obstruction

“…Recently, few studies compared the outcomes of TCLDCR and EXDCR procedures for the treatment of nasolacrimal duct obstructions ( 12 - 15 ). Yener et al ( 15 ) revealed that the functional success rate was 93.2% in EXDCR with a follow-up of 8 years and 85.7% TCLDCR with a follow-up of 7 years. The difference in the success rate was not statistically significant.…”

“…Although TCLDCR has been demonstrated to be a safe and effective method in the treatment of nasolacrimal duct obstruction, there are few studies comparing the outcomes of TCLDCR and EXDCR ( 12 - 15 ). Therefore, in the present study, we aimed to compare the results of TCLDCR and EXDCR in the treatment of patients with acquired nasolacrimal duct obstruction.…”

Success and complications of endoscopic laser dacryocystorhinostomy vs. external dacryocystorhinostomy: A systematic review and meta-analysis

“…The success rates of these procedures as reported in the literature vary from 80–95%, 63.3–90.1%, and 57–100%, respectively. [ 1 - 3 ] Although transcutaneous external dacryocystorhinostomy (ExDCR) is still regarded as the gold standard among all, a few studies have shown superior results with the endonasal approach. [ 4 , 5 ] According to a Cochrane database systematic review in 2017, there is little or no difference in success rates between mechanical endonasal DCR and external DCR.…”
