title: Our experience with transcanalicular laser-assisted endoscopic dacryocystorhinostomy (TCLADCR) in patients of chronic dacryocystitis with deviated nasal septum.
abstract: The purpose of this study is to study the operative difficulties and success rate of transcanalicular laser-assisted endoscopic dacryocystorhinostomy in patients of chronic dacryocystitis with deviated nasal septum (DNS). A prospective interventional clinical study of 36 consecutive patients suffering from chronic dacryocystitis with nasolacrimal duct obstruction with DNS undergoing primary TCLADCR from March to June 2011 was carried out. Diode laser was used to create a 16-mm(2) ostium which was enlarged to 64 mm(2) using Blakesley's forceps. Success was defined as anatomical patency and absence of symptoms at 12 months of follow-up. Out of the 36 patients, 25 were females with ages 20-72 years, and 19 were left sided. There were 12 high, 12 mid and 12 basal DNS towards the side of surgery, mild to moderate in severity. Intraoperatively there was difficulty in visualising the aiming beam in the nose, tedious manipulation of endoscope and excessive bleeding in 3 patients. Increased bleeding and failures were significantly higher in high DNS (Fisher exact test-2 tailed: 0.0045). The procedure was successful in 94.4 % cases with average ostium size of 21.94 mm(2) at 12 months and no statistically significant difference in success rates between mild and moderate DNS (Fisher exact test-2 tailed: 1.000). Also there was no difference in the complication rate between mild and moderate DNS (Fisher exact test-2 tailed: 0.0841). TCLADCR is an effective procedure in patients with mild to moderate mid and basal DNS and obviates the need for multiple procedures and a cutaneous scar.
