OBJECTIVE: Meningomyelocele is a common congenital neural tube defect. To reduce complications, we need early surgery and a multidisciplinary approach. In this study, we administered platelet-rich plasma (PRP) to babies with meningomyelocele following corrective surgery to minimize cerebrospinal fluid (CSF) leakage and accelerate the healing of the immature pouch tissue. We compared these with a control group that did not receive PRP. PATIENTS AND METHODS: Of the 40 babies who had surgery with the diagnosis of meningomyelocele, 20 patients received PRP after surgical repair, and 20 were followed up without PRP. In the PRP group, 10 of the 20 patients underwent primary defect repair, the other 10 underwent flap repair. In the group that did not receive PRP, primary closure was performed in 14 patients and flap closure in six. RESULTS: In the PRP group, CSF leakage occurred in one (5%) patient, and none developed meningitis. Partial skin necrosis occurred in three (15%) patients and wound dehiscence in three (15%) patients. In the group that did not receive PRP, CSF leakage occurred in nine (45%) patients, meningitis in seven (35%), partial skin necrosis in 13 (65%), and wound dehiscence in seven (35%) patients. The rate of CSF leakage and skin necrosis in the PRP group was significantly (p<0.05) lower than that in the PRP group. Furthermore, wound closure and healing were also improved in the PRP group. CONCLUSIONS: We have shown that PRP treatment of postoperative meningomyelocele infants facilitates healing and lowers the risk of CSF leakage, meningitis, and skin necrosis.
