To analyse the radiological features of the bony nasolacrimal duct before and after functional endoscopic sinus surgery, and document the incidence of surgically induced dehiscence.
A retrospective case series analysis was conducted of 63 consecutive patients who underwent uncinectomy as a part of 118 functional endoscopic sinus surgical procedures. All patients underwent pre- and post-operative computed tomography scans. Axial computed tomography images at the level of maxillary sinus were evaluated for the presence of bony nasolacrimal duct dehiscence, osteitis and completeness of uncinectomy.
The rate of nasolacrimal duct dehiscence prior to surgery was 6.8 per cent (8 out of 118 cases). Nasolacrimal duct dehiscence as a consequence of surgery was observed in 3.3 per cent of cases (4 out of 118), with a further 4.2 per cent (5 out of 118) showing post-operative reactive bony change of the nasolacrimal duct in the absence of dehiscence.
The incidence of nasolacrimal duct injury observed was much lower than that previously reported in the literature.
分析功能性鼻内镜鼻窦手术前后鼻泪管骨质的影像学特征，并记录手术引起的鼻泪管骨质缺损的发生率。
对连续63例患者进行回顾性病例系列分析，这些患者均接受了钩突切除术，该手术是118例功能性鼻内镜鼻窦手术的一部分。所有患者均接受了术前和术后的计算机断层扫描。对上颌窦水平的轴向计算机断层扫描图像进行评估，以确定是否存在鼻泪管骨质缺损、骨炎以及钩突切除术的完整性。
手术前鼻泪管骨质缺损的发生率为6.8%（118例中有8例）。手术导致的鼻泪管骨质缺损发生率为3.3%（118例中有4例），另有4.2%（118例中有5例）在无骨质缺损的情况下出现了鼻泪管术后反应性骨质改变。
观察到的鼻泪管损伤发生率远低于先前文献报道的发生率。
