阴茎冠状沟前缘、后缘及临床意义

Anterior and Posterior Lines of the Coronary Sulcus of the Penis and Their Value in Circumcision

目的:观察阴茎冠状沟的解剖特征并进行宽度测量,探讨其在包皮环切术中的应用价值。方法:对269例男性阴茎冠状沟宽度进行观察,本组年龄19～66岁,平均28岁。其中包皮过长137例,包茎11例,包皮环切术后31例(其中系包皮过长者30例,包茎者1例),包皮正常90例。在绷紧冠状沟黏膜状态下以游标卡尺测量冠状沟12点钟位处即背侧正中的宽度。比较冠状沟宽度在包茎、包皮过长和正常者之间的差异情况。结果:冠状沟黏膜相对平坦、光整、活动度小。冠状沟前缘多较模糊,冠状沟后缘一般较清晰、容易识别。冠状沟宽度值包皮过长组(4.32±3.44)mm,包茎组(4.06±2.68)mm,包皮正常组(4.22±3.06)mm,3组之间的差异不具有显著性(P>0.05)。结论:阴茎冠状沟的宽度在临床上应该得到重视;包皮环切术时宜以冠状沟后缘为标志进行内板切口的定位。

Objective： To explore the anatomical features and measure the width of the coronal sulcus of the penis. Methods： We observed the coronal sulcus of the penis in 269 males aged 19 -66 （mean 28） years. Among them, 137 had redundant prepuce, 11 had phimosis, 90 were normal men, and 30 had been circumcised for redundant prepuce and 1 for phimosis. The width of the suleus was measured with the vernier caliper at the 12 o＇cloek position, i. e. , the middle point of the dorsal. The results were compared among different groups. Results ： The mueosa of the suleus was relatively flat, smooth and not so active. Generally, the anterior line of the coronal suleus was indistinct, whereas the posterior line was clear and easy to be identified. The widths of the coronal suleus were （4.32 ± 3.44）, （4.06 ± 2.68） and （4.22 ± 3.06） mm in the redundant prepuce, phimosis and normal groups, with no statistically significant differences among the three （ P 〉 0. 05 ）. Conclusion ： Enough attention should be paid to the width of the coronal sulcus of the penis in clinical practice. The posterior line of the coronal suleus should be chosen as the positioning standard for inner incision in circumcision.
