Effectiveness depends on a watertight closure; however, there are challenges to achieving such. Often, a separate, watertight dural closure is difficult due to the thinness and fragility of the dural membrane. This video demonstrates the approach utilizing a previously described myofascial rotation of the bilateral paraspinal muscles to construct a robust closure even without the need for a separate dural closure or patch reinforcement. This method has been associated with improved primary closure rates and fewer postnatal procedures.

Single- and two-layer fetoscopic closure techniques have been described but there is concern for the ability to achieve watertight closure. Watertight closure is critical for preventing postoperative complications, particularly cerebrospinal fluid leakage and wound dehiscence.
