목적 : To report the outcomes of transcanalicular diode laser-assisted revision surgery for failed dacryocystorhinostomy (DCR) with/without distal or common canalicular obstruction.
방법 : The medical records and recorded videos of consecutive transcanalicular diode laser-assisted revision surgeries performed for failed dacryocystorhinostomy between May 2011 and May 2015 were reviewed. Cases of unavailability of video and cases lost to follow-up after surgery were excluded from the study. With respect to the level of obstruction, lacrimal drainage systems were divided into Group 1 (obstruction at the level of the ostium) and Group 2 (obstruction at the level of the distal or common canaliculus). Data associated with anatomical and functional success were analyzed.
결과 : Revision DCR surgeries were performed on 68 patients during the study period. Transcanalicular diode laser-assisted revision surgeries were performed on 48 eyes of 39 patients. Mean follow-up period after revision surgery was 13.3 ± 12.6 months. Overall anatomical success rate was 83.3% (40/48) and functional success rate was 68.8% (33/48). Anatomical success rates and functional success rates in the two groups showed no significant difference [80.0% (24/30) vs. 86.7% (13/15), p=0.699; 70.0% (21/30) vs. 66.7% (10/15), p=1.000, respectively].
결론 : Transcanalicular diode laser-assisted revision surgery may be an alternative technique for failed dacryocystorhinostomy. Distal or common canalicular obstruction did not affect the outcomes of revision surgeries.
