OBJECT An optimal entry point for endoscopic third ventriculostomy (ETV) helps protect critical structures from undue manipulation. A commonly accepted ideal entry point is 3 cm from the midline and 1 cm anterior to the coronal suture. The authors of this study reexamine this ideal entry point. METHODS Trajectory views from MR images or CT scans used for cranial image guidance in 53 patients (age range 3-85 years) who had undergone ETV were retrospectively evaluated. The trajectory from the… CONTINUE READING
