摘 要:目的应用超声和解剖对照的方法 ,对闭孔内肌进行超声识别,以期为男性闭孔内肌的影像学检查提供一种有效的新方法。方法先对10具防腐尸体进行解剖,了解闭孔内肌位置、形态、结构及周围的毗邻关系,然后对一例新鲜男性成人尸体进行经直肠超声检查,观察闭孔内肌声像图表现,测量其厚度,在超声引导下对疑似闭孔内肌的肌肉进行穿刺定位,解剖后确认。结果经解剖证实,超声所定位的肌肉为闭孔内肌,声像图表现为两头稍尖,中央略膨隆的纺锤形。超声测量闲孔内肌的平均厚度,右侧:13.6mm,左侧:13.7 mm。新鲜标本防腐处理后耻骨直肠肌的平均厚度为,右侧:13.16 mm,左侧:13.17 mm。结论采用经直肠超声对男性闭孔内肌进行识别和观察,是影像学的一种新手段。Objective To study the appearance of the normal male obturator internus using transrectal ultrasound compared with anatomy examinations to advance the knowledge of the male android pelvis muscle and to provide a new imaging method to observe the normal male obturator internus. Methods Ten formalin fixed cadavers were dissected to examine the appearances and structures of the obturator internus and its relationship with the peripheral organs. The obturator internus were also observed in a fresh male cadaver using transrectal ultrasound. In a fresh male cadaver, the obturator internus were located by transrectal sonography, the muscle was confirmed by anatomy, and the thickness was measured. Results The ultrasonographic observations of the location of the obturator internus were confirmed by anatomy for the fresh cadaver. The visible fusiform sonogram was observed in the sonographic image. The right and left obturator internus thickness measurements were 13.6 and 13.7 mm by sonographic image, respectively, while in formalin-fixed fresh cadaver the measurements were 13.16 and 13.17 ram, respectively. Conclusion Using transrectal ultrasound to recognize and observe the obturator internus is a new imaging method.
