Purpose: A trend in large myelomeningocele defect repair involves soft tissue closure with muscle and fascial flap techniques to provide a durable, protective, and tension-free soft tissue covering. We propose that composite tissue closure yields superior outcomes regardless of defect size.
Methods: We present a retrospective review of our 15-year, single-institution experience using this approach. Our study includes 45 consecutive patients treated using combinations of muscle and fascia flaps for primary closure of a myelomeningocele defect.
Results: Lumbosacral fascia closures were used in 18 cases (40%) with paraspinous muscle closure and 12 cases (27%) without paraspinous closure. Fascial closure with bony pedicle periosteum and gluteal muscle and fascial closure were used in four cases (9%) each. Other techniques included latissimus dorsi flaps and combinations of these techniques. Postoperatively, none of our patients experienced a cerebrospinal fluid leak, and only one patient required reoperation for skin flap necrosis.
Conclusions: Objective measures show that universal application of flap techniques may lead to better outcomes for soft tissue closure during myelomeningocele repair.
