目的：采用CT三维成像技术重建肌耻骨孔,研究腹股沟疝病人解剖数据。方法：采集2019年3月至2019年12月我院90例腹股沟疝病人的术前CT图像。其中斜疝79例,直疝9例,股疝2例。CT图像导入软件行三维重建。测量重建后肌耻骨孔的解剖数据,比较年龄、性别和体质量指数分组后的差异。结果：肌耻骨孔的平均总宽度为（7.67±0.75） cm,长度（7.34±0.38） cm,上缘长度（5.79±0.79） cm,下缘长度（6.57±0.50） cm,上下两区夹角（120.10±9.36）°。男女分组间的总宽度、长度和上缘长度差异有统计学意义（P<0.05）。年龄分组的上缘长度差异有统计学意义（P<0.05）。体质量指数分组的上下两区夹角差异有统计学意义（P<0.05）。结论：采用CT三维成像技术测量肌耻骨孔可行。采集的肌耻骨孔数据可指导不同年龄、性别以及体质量指数腹股沟疝手术病人的补片制作。

Objective To study myopectineal orifice anatomy of the patients with inguinal groin hernia using three-dimensional imaging technology after reconstructing of myopectineal orifice. Methods Preoperative CT images of 90 patients with inguinal hernia including 79 cases with indirect, 9 cases with direct and 2 cases with femoral were collected in our hospital from March 2019 to December 2019. The data of CT imaging were imported into software for three-dimensional reconstruction. The data of myopectineal orifice anatomy after reconstruction were measured and compared after grouping of age, gender and body mass index. Results The mean total width of myopectineal orifice was(7.67±0.75) cm, length (7.34±0.38) cm, length of upper edge(5.79±0.79) cm, length of lower edge(6.57±0.50) cm, and the upper lower angle (120.10±9.36) °. Difference in total width, length, and upper edge length was statistically significant between male group and female group (P<0.05). There was difference in upper edge length between adult group and old group (P<0.05) and in upper lower angle between body mass index low group and high group (P<0.05). Conclusions Three-dimensional CT ima-ging technology could be feasible to measure the morphology of myopectineal orifice. The data of myopectineal orifice collected in this study would be used to direct prosthetic mesh of inguinal hernia according to different age, gender and body mass index.
