%X <B>OBJECTIVE: </B>Myelomeningocele (MMC) is a prevalent neural tube closure defect often associated with hydrocephalus, necessitating surgical intervention in a significant proportion of cases. While ventriculoperitoneal shunting (VPS) has been a standard treatment approach, endoscopic third ventriculostomy (ETV) has emerged as a promising alternative. However, factors influencing the success of ETV in MMC patients remain uncertain. This retrospective observational study aimed to identify clinical and radiological factors correlating with a higher success rate of ETV in MMC patients.<BR><B>METHODS: </B>Medical records of MMC patients who underwent ETV at a tertiary care center between 2015 and 2021 were reviewed. Demographic, clinical, and radiological data were analyzed. ETV success was defined as the absence of further hydrocephalus treatment during follow-up.<BR><B>RESULTS: </B>Of 131 MMC patients, 21 met inclusion criteria and underwent ETV. The overall success rate of ETV was 57.1%, with a six-month success rate of 61.9%. Age ≤ 6 months was significantly associated with lower ETV success (25%) compared to older patients (76.9%) (OR: 0.1; 95% CI 0.005-2.006; p = 0.019). Radiological factors, including posterior fossa dimensions and linear indices, did not exhibit statistically significant associations with ETV success.<BR><B>CONCLUSIONS: </B>Age emerged as a significant factor affecting ETV success in MMC patients, with younger patients exhibiting lower success rates. Radiological variables did not significantly influence ETV outcomes in this study. Identifying predictors of ETV success in MMC patients is crucial for optimizing treatment strategies and improving patient outcomes.
