A rare case surgery repair for pediatric sphenoethmoidal encephalocele with single-step transfrontobasal approach

Background: Basal encephalocele (BEC) is the rarest type of all encephaloceles. Several methods were used to close and repair the bony defect and prevent CSF leakage. Here we present a case of a 1-month-old pediatric patient who presented with a sphenoethmoidal basal encephalocele with a single transfrontobasal approach. Case Presentation: A female infant one-month-old with diagnosed large sphenoethmoid encephalocele (basal encephalocele). From the 3D CT scan reconstruction, we found a defect in the planum sellae and ethmoid region with a maximum line of 2.84 cm x 2.89 cm. We performed a transfrontobasal approach by using titanium mesh/plate. After follow-up, we did not find CSF leakage. Conclusion: Uncertainty persists on the best way to restore BEC. In this instance, we used single TBF approaches to seal and repair the basal encephalocele. There are no signs of infection or CSF leakage throughout the follow-up.
