Anterior trans-frontal endoscopic resection of third-ventricle colloid cyst: how I do it.

Background: The endoscopic technique has been recognised as a viable and safe alternative to microsurgery for the treatment of third-ventricle colloid cyst. However, the standard precoronal endoscopic approach does not always provide an adequate visualisation of the attachment of the cyst to the velum interpositum. Using a more anterior approach, it is easier to reach the roof of the cyst and its possible adherences with the tela choroidea.
Method: The authors describe step by step the anterior trans-frontal endoscopic approach for management of third ventricle colloid cyst.
Conclusions: The described approach has shown to be safe, quick and effective for the treatment of third-ventricle colloid cyst.
