目的/假设探讨骨鼻泪管（NLD）下端开口与上颌窦前壁的解剖关系。研究设计解剖调查。方法采用高分辨率计算机断层扫描（HRCT）技术，对206例患者进行了骨性NLD下端及其与上颌窦前壁的关系的详细解剖研究。根据HRCT图像，将观察到的特征分类为融合型或分离型。此外，上颌窦前壁和内侧壁之间的角度被分类为前模式或侧模式。结果HRCT扫描显示NLD解剖融合型占40.05%，分离型占59.95%。上颌窦前壁与内侧壁夹角的前模式占64.1%，外侧模式占35.9%。在165例解剖融合中，15.8%的病例出现前角模式，84.2%的病例出现侧角模式。247例解剖分离中，97.2%为前型，2.8%为侧型。结论骨性NLD下端与上颌窦前壁的外科解剖表现出不同的关系。术前使用HRCT和了解特定类型的解剖特征可能有助于计划和实施成功的内窥镜下上颌骨内侧切除术。证据水平[j] .喉镜杂志，2019,29 (10):1030-1034
Objectives/Hypothesis To examine the anatomic relationships between the lower end opening into the inferior meatus of the bony nasolacrimal duct (NLD) and the anterior wall of the maxillary sinus. Study Design Anatomical investigation. Methods A total of 206 individuals were recruited for detailed anatomic investigation of the lower end of the bony NLD and their relation to the anterior wall of the maxillary sinus by high-resolution computed tomography (HRCT) imaging. The observed features were classified as either a fusion type or separation type, according to the HRCT images. Additionally, the angle between the anterior and medial wall of the maxillary sinus was classified as either an anterior mode or lateral mode. Results The NLD anatomical fusion type was found in 40.05% and the separation type in 59.95% of the HRCT imaging scans available. The anterior mode of angle between the anterior and medial wall of the maxillary sinus was present in 64.1% of the images, and the lateral mode in 35.9% of the images. In 165 cases of anatomical fusion, the anterior mode of angle was present in 15.8% and the lateral mode in 84.2% of cases. In 247 cases of anatomical separation, the anterior mode was present in 97.2% and the lateral mode in 2.8% of cases. Conclusions The surgical anatomy of the lower end of the bony NLD and anterior wall of the maxillary sinus displays varied relationships. Preoperative use of HRCT and an awareness of the particular type of anatomical feature present are likely to aid in planning and performing successful endoscopic medial maxillectomy.
