Median Raphe Cyst of the Perineum

Here, we present a protocol to treat patients diagnosed with an epididymal cyst using microscopic cyst resection. Based on microscopic manipulation, a largely improved visualization of the subtle tissue structures of the epididymis was obtained, so the cyst could be clearly dissected apart and completely removed...

Besides mean, the median is a widely used measure of central tendency. Typically, median is defined as the central or middle value of a data set, measured by arranging the data elements in an increasing or decreasing order. Since this middle value is not affected by the precise numerical values of the outliers or fluctuations, it is insensitive to them. Hence, in cases where a data set may have outliers or the extreme values are not known, the median is a better measure of the central tendency...

This protocol details a minimally invasive endoscopic technique for the removal of third ventricular colloid cysts. It provides a comprehensive overview of preoperative preparations, surgical steps, and postoperative outcomes, emphasizing reduced recovery time, minimal complications, and total cyst removal. This approach is a safe and effective alternative to traditional...

In general, the sign test serves as a nonparametric method to test hypotheses about the median of a single population when the data does not follow a known distribution. This simplicity makes it particularly useful for small sample sizes or when the assumptions of parametric tests cannot be met. The process begins with identifying a null hypothesis, typically stating that the population median equals a specific value. The alternative hypothesis could be that the median is either not equal to,...

The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

We present a surgical approach to treat posterior cruciate ligament cysts by an arthroscopic double posteromedial...
