Botulinum toxin (Bo NT ) injections have been used to reduce muscle spasm in the presence of severe pelvic pain. However, while pubococcygeus is easily accessed vaginally, injection to obturator internus is more complex – with variation in operative technique and needle placement confounding the ability to assess outcomes. We describe a simplified technique for Bo NT injection to obturator internus using neurostimulation under ultrasound guidance.
