OBJECTIVE: Sacral @entity12786 are rare causes of sciatic and sacrococcygeal @entity51 . Although several microsurgical treatments have been described, the optimal treatment has yet to be determined. We describe our initial experience with symptomatic lesions combining 1) cyst fenestration and imbrication and 2) filling the epidural space using vascularized paraspinous @entity121 rotated into the cystic cavity. METHODS: We retrospectively reviewed all consecutive cases of symptomatic @entity12786 treated with microsurgery at our institution between 2003 and 2011. The main outcome measure was self-reported symptom relief. Postoperative imaging, surgical complications, and subsequent treatments were also recorded. RESULTS: Thirty-five @entity1 were treated. Mean age was 52 years. All @entity1 presented with a chief complaint of @entity158 . The mean cyst size was 3.6 cm (largest diameter). Follow-up beyond the initial hospital stay was available in 86% (median 8 months). Ninety-three percent reported improvement in @entity158 at some point during the postoperative course but 50% of those developed recurrent @entity2531 . Postoperative imaging was available in 69% of the @entity1 in whom 92% showed complete obliteration (25%) or reduction in cyst size (67%). CONCLUSIONS: The combination of microsurgical cyst fenestration and the use of vascularized muscle pedicle flaps to fill the cystic cavity and the epidural space results in obliteration or reduction in size of the majority of cysts and is associated with initial improvement in @entity158 in most @entity1 . However, delayed recurrence of @entity158 was common with this technique.
