The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below.

The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling . Some regard them as a part of the sphincter ani externus. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed.

The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx.

The pelvic cavity of the true pelvis has the pelvic floor as its inferior border (and the pelvic brim as its superior border.) The perineum has the pelvic floor as its superior border.

Some sources do not consider “pelvic floor” and “pelvic diaphragm” to be identical, with the “diaphragm” consisting of only the levator ani and coccygeus, while the “floor” also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diaphragm. In practice, the two terms are often used interchangeably.

Inferiorly, the pelvic floor extends into the anal triangle.

Skin grafting is a surgical procedure that involves removing the skin from one area of the body and moving it, or transplanting it, to a different area of the body. This surgery may be done if a part of your body has lost its protective covering of skin due to burns, injury, or illness. Skin grafts are performed in a hospital. Most skin grafts are done using general anesthesia, which means you’ll be asleep throughout the procedure and won’t feel any pain.

An abscess is a collection of pus. Pus is a thick fluid that usually contains white blood cells, dead tissue and germs (bacteria). The usual cause of an abscess is an infection with bacteria. Certain bacteria are more likely to be 'pus-forming' as they make chemicals (toxins) that can damage the body's tissues.

A hematoma is a collection of blood outside of a blood vessel. There are several types of hematomas and they are often described based on their location. Examples of hematomas include subdural, spinal, under the finger or toenail bed (subungual), ear, and liver (hepatic). Some causes of hematomas are as pelvic bone fractures, fingernail injuries (subungual), bumps, passing blood clots, blood clot in the leg (DVT), blood cancers, and excessive alcohol use. Symptoms of hematomas depend upon their location and whether adjacent structures are affected by the inflammation and swelling associated with the bleeding and may include

If your ear is leaking pus, you may have a hole in your eardrum.Your eardrum is stretched across the inner end of your ear canal. It vibrates when sound waves reach it, so you can hear. A hole in your eardrum can be caused by an ear infection. Fluid builds up behind the eardrum. The pressure of the fluid can tear the eardrum. Some people get a hole in the eardrum for other reasons, like hearing a very loud noise. If this happens, the ear may get infected because germs (bacteria) get through the hole. Ear infections happen to adults and children, but they're more common in children. Some things can make you more likely to get an ear infection with discharge. They include getting lots of colds and coughs, living in overcrowded housing, and eating a poor-quality diet
