Botulinum toxin type a (BOTOX) for refractory myofascial pelvic pain

摘要

The etiology of chronic pelvic pain is poorly understood. The condition is usually multifactorial; it has both physical and psychological components. Myofascial pain is a component of chronic pelvic pain. Management of myofascial pain is multidisciplinary and includes use of several different drugs, pelvic floor physical therapy/exercise, and trigger point injection of local anesthetic agents, steroids, botulinum toxin type A (Botox), and various other substances. A number of studies have shown that Botox improves pain symptoms resulting from muscle spasm in the head, neck, and back and other parts of the body. There are few data in the literature, however, on the effectiveness of Botox injection to the pelvic floor muscle (intralevator injection) in the treatment of myofascial pelvic pain.
