<h4>Purpose</h4>Of the many suggested techniques, we used dorsal intercostal perforator artery flap (DIPAF) for the closure of myelomeningocele defects. This study compared the outcomes of primary closure and DIPAF in the closure of myelomeningoceles.<h4>Methods</h4>Data of 24 patients that underwent myelomeningocele surgery at a single institution between November 2015 and September 2019 were retrospectively reviewed.<h4>Results</h4>The primary closure group had 13 patients (54.17%) and the DIPAF group had 11 (45.83%). The mean age was 7.91 ± 13.27 days (1-60 days). Twelve patients were female and 12 were male. In 22 patients, the myelomeningocele sacs were in the lumbosacral region, while in 2, they were in the thoracolumbar region. The mean defect sizes were 14.20 ± 4.62 cm<sup>2</sup> and 18.44 ± 3.49 cm<sup>2</sup> in the primary closure and DIPAF groups, respectively. In each group, four patients had a kyphotic deformity. In the primary closure group, three patients had wound necrosis, two had wound dehiscence, and four had cerebrospinal fluid (CSF) leakage. In the DIPAF group, one patient had wound necrosis and one had CSF leakage. Significantly fewer complications related to the operation area were observed in the DIPAF group (p < 0.05). Increased defect size, kyphotic deformity, and presence of hydrocephalus were found to be risk factors for complications related to the operation area.<h4>Conclusion</h4>This surgical treatment protects neural tissue, prevent CSF leakage, and reduce central nervous system infection rates in myelomeningocele patients. Closure technique with the fasciocutaneous skin flap has more satisfying results than primary closure.
