Trans-eyebrow supraorbital keyhole approach for suprasellar and intra-suprasellar Rathke cleft cysts: the experience of 16 cases and a literature review.

For the treatment of purely suprasellar and some intra-suprasellar RCCs with most of the pituitary occupying the sellar floor, the endoscopic TSKA has the advantage of the minimal invasiveness, excellent visualization of the intrasellar compartment, no additional damage to the underlying pituitary gland, and no risk of CSF leakage. TDI or DI is relative commonly found in treatment of these RCCs. During surgery, care should be taken to avoid damage to the surrounding structures, including the pituitary stalk.
