Purpose Meningomyelocele is a serious pathology that requires immediate surgical treatment. Its management is difficult due to accompanying other pathologies and hydrocephalus. Shunt timing is still controversial. Therefore, this study retrospectively assessed 80 patients in order to improve the shunt timing and management of patients with meningomyelocele. Methods A total of 80 patients were followed up for 18–48 (average, 23) months. Patients were analyzed for the following variables: delivery method and time, head circumference monitoring, shunt timing, complication rates of patients who underwent shunting, during the early or follow-up period, accompanying pathologies, size, and localization of lesion. Results Patients including 46 males and 34 females have been operated. In 40% of patients, the accompanying pathology was determined. Approximately 85% of patients had hydrocephalus, and a ventriculoperitoneal shunt was placed on 36 symptomatic and 22 patients with hydrocephalus that developed during the follow-up. Differences in shunt-related and general complications were not significant between patients who underwent shunt placement during the same session and patients who underwent shunt placement during the follow-up. However, the incidence of cerebrospinal fluid fistula formation from the wound in patients who underwent shunt placement during the same session was significantly lower than those who underwent shunt placement during follow-up. Conclusions Immediate surgery (within the first 48 h) provides positive results, which is consistent with the existing literature. According to the logistic regression analysis, the placement of the meningomyelocele sac in the lumbosacral region is decisive in shunt insertion. Placing the shunt in the same session for patients with hydrocephalus and later for patients who developed hydrocephalus during the follow-up is recommended as a favorable treatment.
