BACKGROUND:

A paradigm shift toward less radicality in the treatment of craniopharyngioma (CP) has increasingly gained recognition. In selected patients, a less invasive approach aiming at cyst decompression may be suitable.

OBJECTIVE:

To present our experience with the endoscopic transcortical-transventricular approach (ETTA) for the treatment of CP located in the third ventricle, describe our surgical technique, and explore the results reported in the literature.

METHODS:

Data for third ventricular CPs treated using ETTA in 2 tertiary medical centers between 2006 and 2020 were retrospectively reviewed. Cystic, mixed lesion, new, and recurrent cases were included. ETTA aimed at cyst fenestration, subtotal or partial tumor resection, managing the hydrocephalus, or a combination of these modalities. Fractionated radiotherapy (RT) was performed (54 Gy in 30 fractions).

RESULTS:

The described approach was …
