Abstract

Objective

To determine the incidence of nasolacrimal duct injury after functional endoscopic sinus surgery radiologically, using computed tomography.

Methods

Fifty patients of either sex who underwent functional endoscopic sinus surgery were evaluated for nasolacrimal duct injury by computed tomography. Computed tomography was conducted pre-operatively, and post-operatively at the end of four weeks, and nasolacrimal duct injury was analysed.

Results

The prevalence of nasolacrimal duct injury dehiscence was 1.16 per cent, with a similar incidence of 1.16 per cent for nasolacrimal duct injury post-operatively. However, no cases of symptomatic nasolacrimal duct injury were recorded.

Conclusion

Computed tomography scan is an effective, non-invasive method to evaluate nasolacrimal duct injury following functional endoscopic sinus surgery, in accordance with evidence-based medicine.
