Abstract

BACKGROUND: Improved intranasal visualization with endoscope allowed easy identification and opening of the lacrimal sac, without need for skin incision.
OBJECTIVES
We studied and described the endoscopic dacryocystorhinostomy which has success rates comparable to those obtained by external approach.
MATERIALS AND METHODS
Endoscopic dacrycystorhinostomy has been used for the treatment of nasolacrimal duct obstruction in 17 patients. The nasolacrimal apparatus related to the lateral nasal wall was approached using endoscopic technique. And bicanalicular nasal silicone tubes were placed during surgery in all cases.
RESULTS
In our cases, it appears that lacrimal obstruction is related with congenital, idiopathic, facial trauma and other nasal or paranasal sinus diseases. Epiphora was relieved in 15 patients (88.2%), with a followup of 6 to 9 months. The causes of failure were granulation formation and obstruction of opening of lacrimal sac in 2 patients.
CONCLUSION
Endoscopic dacryocystorhinostomy appear to be a safe and effective procedure which should be considered as an alternative to external dacryocystorhinostomy for the surgical treatment of nasolacrimal duct obstruction.
