BACKGROUND: Transsphenoidal surgery (TSS) is the main method to remove pituitary neuroendocrine tumor (PitNET), but large or multi-lobulated one is still challenging.
OBJECTIVE: The less invasive simultaneous combined keyhole mini-transcranial approach and standard transsphenoidal approach was used to remove multi-lobulated or hourglass-shaped non-functioning PitNET to avoid the specific complications related to extended TSS.
METHODS: Twenty-one patients of large multi-lobulated or hourglass-shaped PitNET (6 patients were recurrent cases after TSS or transcranial approach) were treated by this simultaneous combined approach. The supraorbital or midline keyhole approach was performed under the operating microscope so that the fine arteries feeding optic apparatus were dissected from the tumor capsule safely and securely and the suprasellar part of the tumor was removed in the extra-capsular fashion in combination with transsphenoidal approach.
RESULTS: Visual function improved after the surgery in 14 (74 %) of 19 patients with preoperative disturbance of the visual fields. Four patients (19 %) developed postoperative deterioration of pituitary endocrine functions requiring permanent hormonal replacement. One patient (4.2 %) suffered cortical laminar necrosis without permanent disorders and another patient (4.2 %) suffered cerebrospinal fluid rhinorrhea but neither was permanent. Postoperative computed tomography detected no subarachnoid hemorrhage in any patient. Gross total removal was achieved in 15 patients (71 %). Five patients (24 %) with subtotal removal and one patient (4.2 %) with partial removal had lateral tumor extension with Knosp classification 3 or 4.
CONCLUSION: The combined method is an effective treatment option to remove complex PitNET safely and securely with dissecting fine arteries on the tumor capsule.
