To determine the incidence of nasolacrimal duct injury after functional endoscopic sinus surgery radiologically, using computed tomography.
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.
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.
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.
通过计算机断层扫描(CT)评估功能性内窥镜鼻窦手术后鼻泪管损伤的发生率。
对 50 名接受功能性内窥镜鼻窦手术的患者进行 CT 检查,以评估鼻泪管损伤情况。术前和术后 4 周时进行 CT 检查,并对鼻泪管损伤进行分析。
鼻泪管损伤裂开的发生率为 1.16%,术后鼻泪管损伤的发生率也相似,为 1.16%。然而,没有记录到有症状的鼻泪管损伤病例。
根据循证医学,CT 扫描是一种有效、非侵入性的评估功能性内窥镜鼻窦手术后鼻泪管损伤的方法。
