Conclusion LITT with septostomy should be considered a viable primary or adjunct treatment modality for SEGAs.This historical review presents the relevant data about the evolution of the surgical treatment of neonatal brachial plexus palsy. Starting with the first clinical description by Smellie in 1754, we will present the initial enthusiasm for the surgery followed by a lack of interest that lasted many years, the resurgence of interest in operative management in the 1970s, and the consolidation in the 1980s of surgery as the standard indication in cases of neonatal brachial plexus palsy without a functional spontaneous recovery.Background Myelomeningocele (MMC) is the most common and severe pathology of open spina bifida compatible with life. Its early closure is an urgent therapeutic objective to reduce the morbidity and mortality of neonates, being a surgical challenge with two major objectives (1) achieve closure of the dural cerebrum-spinal fluid fistula and (2) ensure a stable and durable soft tissue coverage. The use of fasciocutaneous flaps in keystone design is shown as a safe and stable surgical option with excellent aesthetic results in patients with MMC and who presented failed primary closures. Methods Two clinical cases of fasciocutaneous flaps in keystone design were described as a coverage option in patients with lumbosacral MMC, in whom the primary closure was unsuccessful and required a safe coverage as a priority. Results Successful coverage of the lumbosacral defect was performed using keystone flaps in neonatal patients with MMC and previous manipulation of the soft tissues when attempting primary closure, but they have had dehiscence of the wound, with a large area of lumbosacral defect and sizeable defect/back ratio. Conclusions The use of keystone flaps is a useful, accessible, and versatile techniq
