How I do it: The expanded trans/supraorbital approach for large space-occupying lesions of the anterior fossa.

Background: The supraorbital rim often interferes with the required upward movement of the instruments for resection of large frontal-lobe tumours through a classic supraorbital craniotomy. Here, we present the expanded trans/supraorbital approach to overcome these limitations.

Methods: After an eyebrow skin incision, a one-piece bone flap was created incorporating the orbital rim and roof.
