Gerald Curved 18cm — Endoscopic Pituitary Surgery

Gerald Curved 18cm — Endoscopic Pituitary Variant

The 18cm-labelled curved Gerald serves endoscopic transsphenoidal pituitary surgery — the modern approach that has displaced the transcranial approach for the majority of pituitary tumours. The curved tip lets the surgeon dissect within the sellar cavity at angles that clear the endoscope’s optical axis, and the 18cm length matches the working depth from the nostril to the sellar floor via the sphenoid sinus.

The endoscopic transsphenoidal corridor

Endoscopic transsphenoidal pituitary surgery accesses the sella through the nostril → middle turbinate displacement → posterior septum → sphenoid sinus → sellar floor → dura → tumour. The endoscope (0° or 30°) sits in the working corridor alongside the surgical instruments; the curved Gerald’s geometry lets it work in the cavity without crossing the endoscope’s field of view. Removing the tumour piecemeal under endoscopic vision requires this geometric clearance — straight instruments are limited to entering and exiting along a single axis.

Modern pituitary outcomes

Endoscopic transsphenoidal pituitary surgery achieves 80-90% gross-total resection of microadenomas and 50-70% gross-total resection of macroadenomas, with major-morbidity rates under 5% at experienced centres. The curved Gerald is one component of the instrument set enabling these outcomes.
