Giant invasive pituitary adenomas are rare tumors that have been reported to extensively involve the cranial base, as well as other intra- and extra-cranial structures, making surgical resection by traditional approaches impossible. We report two cases, each of a giant invasive adenoma involving the entire length of the clivus and adjacent structures that was resected via a transfacial approach with excellent results. Both tumors were in middle-aged men; one was nonsecreting, and the other secreted follicle-stimulating hormone alpha-subunit. Most previously reported giant invasive adenomas have been prolactinomas. Both tumors were resected via a transfacial approach that incorporated an osteoplastic maxillotomy with palatal division and a posterior pharyngeal incision that provided exposure from the suprasellar region to C2. Both of the patients received postoperative radiation and have done very well. Their cosmetic results were excellent. The complications included postoperative meningitis in one patient and a nasal voice in the other. The transfacial approach provides excellent access for this type of extensive midline tumor requiring resection from the suprasellar region down to the foramen magnum. |
