Dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization

Objective To evaluate the clinical effect of dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization. Methods The retrospective comparative study was used to analyze 120 patients with chronic dacryocystitis in our hospital from June, 2012 to May, 2016, of whom 60 patients were treated with traditional dacryocystorhinostomy, and 60 patients were treated with dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization. Half year after the operation the patients were re-examined for the patency of their lacrimal passages and postoperative complication. The disappearance of tearing and the unobstructed patency of the lacrimal passages were set as the standard of a successful operation. The statistically analyzing was performed. Results Six months after operation, the success rate of dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization was 93.3%, the success rate of traditional dacryocystorhinostomy was 90.0%, without statistical difference between two types of operation (P>0.05). The skin scar formation rate in dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization was 0, while 100% in traditional dacryocystorhinostomy, with statistical significant difference (P=0.00). The success rate of two-stage operation was 100% after dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization for recurrence, while 16.7% after traditional dacryocystorhinostomy, the difference is of statistical significance (P=0.048). Conclusions Dacryocystorhinostomy under nasal endoscope combined with lacrimal duct catheterization is not only reliable, effective method for treating chronic dacryocystitis, but also with less iatrogenic trauma, and no scar.
