Chronic inflammation in the lacrimal sac may lead to thickening of the surrounding bony tissues. This study aimed to assess the thickness of lacrimal bone surrounding the lacrimal sac, and the thickness of maxilla, based on the presence of purulent secretion in the lacrimal sac in patients who underwent EDCR.
Lacrimal bone thickness and the maximum and midpoint maxillary bone thickness of 70 patients (mean age of 49.07 years) who underwent EDCR, were assessed along 3 planes (upper, middle, and lower) using CT of the paranasal sinus. The patients were divided into 2 groups: the 1 who had purulent secretion in the lacrimal sac during the intraoperative period (Group 1) and another who did not have purulent secretion (Group 2).
No significant difference was detected between the 2 groups in terms of maximum and midpoint maxillary bone thickness. The increase in the thickness of lacrimal bone in Group 1 was statistically significant in all the 3 planes as compared to that in Group 2. Cutoff values for the thickness of the upper, middle, and lower plane of lacrimal bone were detected to be 0.710 mm, 0.685 mm, and 0.675 mm, respectively.
The presence of purulent secretion in the lacrimal sac, along with the detected increase in the thickness of the lacrimal bone, as assessed by CT, offers an insight on the lacrimal sac before the surgery.
泪囊慢性炎症可能导致周围骨质增厚。本研究旨在基于接受泪囊鼻腔吻合术（EDCR）患者泪囊内脓性分泌物的情况，评估泪囊周围泪骨的厚度以及上颌骨的厚度。
对70例接受EDCR的患者（平均年龄49.07岁），使用鼻窦CT沿三个平面（上、中、下）评估泪骨厚度以及上颌骨的最大厚度和中点厚度。患者分为两组：术中泪囊有脓性分泌物的患者为第一组（组1），无脓性分泌物的患者为另一组（组2）。
两组在上颌骨最大厚度和中点厚度方面未检测到显著差异。与组2相比，组1泪骨厚度在所有三个平面上的增加具有统计学意义。泪骨上、中、下平面厚度的截断值分别检测为0.710毫米、0.685毫米和0.675毫米。
泪囊内脓性分泌物的存在，以及通过CT评估发现的泪骨厚度增加，为手术前了解泪囊情况提供了线索。
