Endoscopic Laser Dacryocystorhinostomy / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Dacryocystorhinostomy is commonly performed through an external incision. Several transnasal approach were described earlier in this century but they failed to gain popularity probably because of difficult exposure. Whether the endoscopic laser dacryocystorhinostomy improved intranasal visualization and decreased intraoperative complications than external incision. MATERIALS AND METHODS: During recent 3 years, we performed endoscopic laser dacryocytorhinostomy about 10 cases at Joong Ang Gil Hospital. RESULTS: Success rate of revision groups (3 cases) was very good. CONCLUSION: Small-diameter endoscope with angled field of view provides excellent intranasal visualization. Endoscopic laser dacryocystorhinostomy avoids the possibility of pathologic scar formation and injury to the medial canthus. Endoscopic laser dacryocystorhinostomy appears to be the safe treatment especially for revision procedure.
