However, Anal uss, the normal thickness does not exceed 4 mm even in the elderly. However, the thickness measured ایرانی جدید ملایر در on the probes Anal uss, as larger probe diameters lead to thinning of the surrounding structures.
The intersphincteral space, with fibers of the corrugator muscle as a continuation of the rectal longitudinal muscle, is seen endosonographically as a thin hypoechoic layer containing hyperechoic connective-tissue septa, representing the border areas Anal uss the hypoechoic IAS and the first less echogenic layer in the EAS.
At this level, the ischioanal fossa, anococcygeal ligament, and coccyx can be visualized, provided that appropriate acoustic penetration is produced.

Prevalence of faecal Anal uss in adults aged 30 years or more in general population. The remaining muscles forming the levator ani muscle the coccygeus muscle, iliococcygeus muscle, and pubococcygeus muscle are identifiable with EUS only to a limited extent, but can be seen as an inhomogeneous, mostly hyperechoic layer with increasing cranial distance to the rectal wall.
The IAS can regularly be seen as a homogeneous hypoechoic layer with a thickness of mm, with no significant sex-dependent differences. Int J Colorectal Dis.

Comparison of transperineal and endoanal ultrasound in detecting residual obstetric anal sphincter injury. The pectinate line and the crypts are often not visible, Anal uss, mainly due to compression of the anal canal by the endorectal probe.

Endoanal Ultrasound scans are not usually performed during the first 3 months of pregnancy, Anal uss. The anal canal is generally 0. Adequate differentiation is possible in the hyperechoic border area between the ultrasound probe and the mucosa or the anal cutis : the hypoechoic, extremely thin mucosa, which often cannot be recognized as a defined layer, due to a lack of the muscularis and its very thin diameter; the hyperechoic submucosa and subcutis ; and the hypoechoic IAS, with the adjacent partly hypoechoic and partly hyperechoic intersphincteral space corresponding to the corrugator ani muscle, Anal uss.

It is important to appreciate that the hyperechoic structures are not directly imaged, but instead represent ultrasound artifacts indicating borderline areas behind which the real anatomical structures are imaged, such as the mucosa and muscularis propria—especially when older ultrasound equipment is used.
Anal uss for diagnosis and therapy. It is of great importance to understand that the shape and configuration of the EAS differs significantly between males and females. Ultrasound scans are also used to look for muscle damage or thinning. These include occasional minor discomfort, minor bleeding and, very rarely, perforation of the bowel wall.
