cen·tral ten·don of per·i·ne·um

[TA]
the fibromuscular mass between the anal canal and the urogenital diaphragm in the median plane onto which several perineal muscles insert (bulbospongiosus, external anal sphincter, superficial, and deep transverse perineal muscles); midline episiotomies extend into this structure.

perineal body

Etymology: Gk, perineos, perineum; AS, bodig
a mass of tissue composed of muscle and fascia between the vagina and rectum in females and between the scrotum and rectum in males.

perineal body

A pyramidal fibromuscular mass which is intimately linked to the integrity of the pubic floor, especially in females, the rupture of which during vaginal delivery predisposes women to uterine, rectal and bladder prolapse. It is located at the midline of the perineum, at the junction between the urogenital triangle and the anal triangle.

perineal

pertaining to the perineum.

perineal body
central tendon of the perineum. The fibromuscular mass in the median plane of the perineum where the bulbospongiosus and external anal sphincter muscles, and the levator ani and transverse perineal muscles attach.
perineal fistula
see perianal fistula.
Gelpi perineal retractor
a small self-retaining tissue retractor.
perineal hernia
a defect in the pelvic diaphragm that permits deviation of the rectum and protrusion of pelvic fat and abdominal contents, particularly the prostate and urinary bladder. Clinical signs include a uni- or bilateral ventrolateral perianal swelling with constipation or straining. Seen most often in middle-aged, male dogs, but occurs rarely in females and in cats.
perineal laceration
laceration of the perineal area such as by the birth of a foal. Three degrees of severity are recognized. First degree laceration is when only the mucosa of the vulva and vagina are involved. Second degree is when the submucosa and muscularis layers of the vulva, the anal sphincter and the perineal body are involved. Third degree is when there is also tearing through the rectovaginal septum, the muscles of the vagina and rectum, and the perineal body.
perineal reconstruction
various surgical techniques are used to repair perineal lacerations. It is necessary to reconstruct the rectal floor and vaginal roof.
perineal reflex
stimulation of the perineum causes contraction of the anal sphincter and flexion of the tail. It is a test of the integrity of the caudal spinal segments and the pudendal nerve. Called also the anal reflex.
perineal sling
a surgical technique that uses a fascial strip under the urethra to increase resistance to urine flow in the treatment of urinary incontinence.

Perineal body defects are often found in patients who have an enlarged vaginal introitus or a history of straining or prior episiotomy, for instance, and addressing these defects is a key part of posterior wall repair that is too often neglected.
I also often perform a perineorrhaphy to repair the perineal body and help with vaginal support.
But from the viewpoint of a vaginal and pelvic reconstructive surgeon, he embodied a major misconception in his statement, "The perineal membrane and perineal body are not very crucial for pelvic organ support.
Identify the rectovaginal septum and attach it to the medial fascia of the levator ani and reconstructed perineal body with permanent, nonabsorbable sutures.
The pubocervical fascia fuses with the perineal membrane and the rectovaginal septum merges with the perineal body inferiorly.
Moreover, the single incision allows access to anal sphincter muscles and the perineal muscles for a perineoplasty, which improves support and thickness of the perineal body.
This means repairing both the external and internal sphincter, reconstructing the perineum, and attaching the rectovaginal septum to the perineal body.
LOUIS -- Proper reconstruction of the perineal body is a key component of successful vaginal prolapse repair, so a clear understanding of its anatomy is imperative, Dr.
