This study examined the outcome of direct visualization endonasal DCR, performed by young surgeons and residents.Methods: A retrospective case series of 75 consecutive endonasal DCRs performed under direct visualization from July 2002 to July 2004 were reviewed. Surgery was performed by surgeons and residents who had received no special training in the procedure. Full success was defined as no symptoms of tearing after surgery and anatomical patency with fluorescein flow on nasal endoscopy or patency to lacrimal syringing. Partial success was defined as a tearing decrease compared with prior to surgery and with anatomical patency, and failure was defined as no significant improvement in persistent tearing. The average follow-up duration was 26.83 ± 16.26 (range 6–55) months.Results: Seventy-five DCRs were performed on 63 patients (four male, 59 female) of mean age 49.44 ± 16.63 (range 21–85) years. The surgery was successful in 54/75 eyes (72%), 37/54 eyes (68.5%), and 30/42 eyes (71.4%) at 6, 12, and 24 months, respectively. Partial success was achieved in 13/75 (17.3%), 9/54 (16.7%), and 9/42 (21.4%), and the failure rates were 10.7%, 14.8%, and 7.1% at 6, 12, and 24 months, respectively. The overall functional success with this technique was 74.7% and the overall anatomical patency was 92.0%. There were no serious complications arising from the surgery; three minor complications were documented, ie, an incorrectly placed silicone tube in the lower canaliculus, tube prolapse, and postoperative bleeding which needed nasal packing and eventually a developed retention cyst in the nasal cavity.Conclusion: Endonasal DCR under direct visualization is a simple technique with minimal complications and a low learning curve, without the necessity for expensive instruments.Keywords: endonasal DCR, dacryocystorhinostomy, lacrimal surgery, nasolacrimal duct obstructionPreechawai PDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2012, Iss default, Pp 1297-1301 (2012)
